E-sata, solid, and udisks (part 2)

In my first post about e-sata, solid and udisks I wrote about how to hack udisks to inform solid that a disk attached to a specified sata port is actually a removable disk. Udisks-1.0.3 includes a modified patch that allows to do that without applying the patch ourselves. We still need to add the udev rule to indicate which sata port is to be considered "non system internal". The udev rules is slightly diferent from the one I wrote about in my last Solid post:

File /etc/udev/rules.d/99-esata.rules

DEVPATH=="/devices/pci0000:00/0000:00:1f.2/host4/*", ENV{UDISKS_SYSTEM_INTERNAL}="0"

Change the DEVPATH to match your e-sata port. You can find it using the command:

Code

evolucao ~ # find /sys/devices/ -name sdb /sys/devices/pci0000:00/0000:00:1f.2/host4/target4:0:0/4:0:0:0/block/sdb

Then reload udev rules after creating/editing the file above: udevadm control --reload-rules

Now the bad news: udisks includes several attributes to a disk, among then are "system internal" and "removable". Removable means removable media (like optical discs, card readers, etc). System internal means the device is "fixed" to the computer, it cannot be removed without turning the computer off, like sata disks. E-sata is in between those two, for sure it is not system internal and technically it is not removable media according to udisks criteria too.

Currently Solid uses udisks' eject command to eject e-sata disks but since an e-sata disk is not removable media and the disk has not actually been removed (detached from the e-sata port) udisks signals that a new disk is available and kded remounts the disk right after the eject command succeeds (bug #277517).


We could use udisks' detach command instead of eject, but udisks seems to refuse to use it with devices with removable flag set to false, which is the case for e-sata disks. Anyway, sometimes we just want to unmount the partition but not turn the disk off, in that case udisks' detach command is inadequate since you will need to turn the disk off and on to use it again.

I think:  1. Solid should stop using udisks' eject command for e-sata partitions (/dev/sdb1, /dev/sdb2, etc) and use the umount command instead. 2. For the entire e-sata disk (/dev/sdb) we should use udisks' detach command, but that will only work when 3. someone fixes udisks to allow executing the detach command for all non system internal devices and not only for the removable ones.

We can do #1 right now. #2 requires some GUI to call the detach command, something that can be used in device notifier plasmoid. #3 is upstream bug :-/

When I have more time I will try to solve this, but for now I am busy and with a dead line approaching, so if someone wants to take the task to fix this problem feel free to do it.

E-sata, solid, and udisks

Last year I wrote about how to hack hal to recognise disks attached to an e-sata port as removable. Now that udisks is the default disk manager in Solid I will explain how to hack udisks to do the same:

1. The hal hack is just a xml file that overrides disk's removable flag. With udisks things are a bit more complicated. I had to apply this patch to udisks and recompile it. The patch adds the flag UDISKS_FORCE_SYSTEM_INTERNAL, which lets us mark the disk as internal or external (AKA removable).
2. Restart udisks. Just kill it and it will restart automatically: killall udisks-daemon # as root
3. After that we need to add an udev rule which will actually mark the disk as removable:

File /etc/udev/rules.d/99-esata.rules

DEVPATH=="/devices/pci0000:00/0000:00:1f.2/host4/*", ENV{UDISKS_FORCE_SYSTEM_INTERNAL}="0"

Change the DEVPATH to match your e-sata port. You can find it using the command:

Code

evolucao ~ # find /sys/devices/ -name sdb /sys/devices/pci0000:00/0000:00:1f.2/host4/target4:0:0/4:0:0:0/block/sdb

4. Reload udev rules: udevadm control --reload-rules

That is it :-)

There is already a bug entry about the e-sata problem in udisks' bugzilla. In fact, I found the UDISKS_FORCE_SYSTEM_INTERNAL patch in that bug entry.

E-sata and Solid

Some days ago a guy asked in the kde-hardware-devel mailing list how to make disks connected to an e-sata port to behave like removable disk in KDE. I have a notebook (Sager np7652) with one e-sata port and had this problem too, but have never tried to fix that, until now. I think what I have found can help other people too so I am writing this post.

After some tries I found a way to tell hald that my disks' partitions come from a removable disk. That works but have an inconvinience, I needed to create one configuration file per partition. Some more tries and finally I got to configure hald to treat all disks connected to my e-sata controller as removable:

1. Add this file to your system:
   
   

   File /etc/hal/fdi/policy/40-e-sata.fdi

   <?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- --> <deviceinfo version="0.2"> <device> <match key="linux.sysfs_path" contains="/sys/devices/pci0000:00/0000:00:1f.2/host4/"> <merge key="volume.ignore" type="bool">false</merge> <merge key="@block.storage_device:storage.removable" type="bool">true</merge> </match> </device> </deviceinfo>

2. Change the contains part to match your e-sata controller's. You can find it using the command:
   

   Code

   evolucao ~ # find /sys/devices/ -name sdb /sys/devices/pci0000:00/0000:00:1f.2/host4/target4:0:0/4:0:0:0/block/sdb

3. Restart hald: /etc/init.d/hald restart
4. That's it :-)

The strange thing is that the file /sys/class/block/sdb/removable contains 0, it should contains 1 since the disk is removable. Maybe it is a kernel bug.

Hal is deprecated for some years now, KDE SC, more precisely Solid, is the only desktop/library that uses it extensively. When we, Solid metal-workers, finish Solid transition to udisk and upower probably hal is gonna vanish for ever.

In less than two weeks there will a Solid Sprint in Madri (Spain), I will be there :-), and we are going to discuss how far we are from the end of this transition. Honestly I like hal, it is flexible from users point of view. I have never used udisk and I do not know if it possible to workaround a problem in the kernel such as this one about disks connected to a e-sata controller using udisk. I hope it is.

Hotkey buttons and udev

As many notebooks out there mine has some hotkey buttons for (de)activate the wifi card, bluetooth controller, webcam, etc. With the buttons sometimes the notebook also has leds to indicate which hardware is activated at the moment, unfortunately my notebook only has leds for wifi and bluetooth, not for the webcam. More unfortunately yet the leds for wifi and bluetooth is the same led but with different color to indicate when only one of them are activated, but I must say Clevo, the manufacturer of my notebooks' barebone, did not make a good choice selecting the colors orange and green :-( It is very difficult to distinguish between the states wifi on / bluetooth off and wifi off / bluetooth on. Even the state wifi on / bluetooth on is not easy to notice. To minimize that problem I created some udev rules and some scripts to open a KDE notification dialog every time they are activated or deactivated. Everybody in Linux "world" must have heard of udev, the system daemon which receives events from the kernel and run programs or scripts based on rules storared in /etc/udev/rules.d or /lib/udev/rules.d. In my case I added my rules to /etc/udev/rules.d:

File /etc/udev/rules.d/50-lvs-rfkill.rules

SUBSYSTEM=="rfkill", RUN+="lvs-rfkill.sh"

File /etc/udev/rules.d/50-lvs-webcam.rules

# Change the idProduct and idVendor attributes to your camera's. # Use lsusb to find them. SUBSYSTEM=="video4linux", ATTRS{idProduct}=="0343", ATTRS{idVendor}=="5986", RUN+="lvs-webcam.sh"

Then run this to reload the rules:

Reload udev rules

udevadm control --reload-rules

Now we need to create the scripts lvs-rfkill.sh and lvs-webcam.sh and give execution permission to them (chmod 755):

File /lib/udev/lvs-rfkill.sh

#!/bin/sh find_display() { if [ -r "/proc/$1/environ" ] then perl -ne 'if ( /DISPLAY=([^:]+){0,1}(:\d+)(.\d+){0,1}/ ) { print "$1$2$3\n"; }' < /proc/$1/environ fi return 0 } user_loop() { OLD_DISPLAY=$DISPLAY ps -C kwrapper -C kwrapper4 h -o pid,user | while read pid user do grep -q ksmserver /proc/$pid/cmdline &> /dev/null || continue export DISPLAY=$(find_display $pid) su - $user -c "$1" done export DISPLAY=$OLD_DISPLAY unset OLD_DISPLAY sleep 1 } title= msg= case $RFKILL_TYPE in wlan) title="Wireless" case $ACTION in add|change) case $RFKILL_STATE in 0) msg="Wireless disabled" ;; 1) msg="Wireless enabled" ;; 2) msg="Wireless disabled by hardware" ;; esac ;; remove) msg="Wireless disabled" ;; esac ;; bluetooth) title="Bluetooth" case $ACTION in add) msg="Bluetooth enabled" echo 1 > /sys/$DEVPATH/state ;; remove) msg="Bluetooth disabled" ;; esac ;; esac if [ "$msg" != "" ] then user_loop "$(ls /usr/kde/*/bin/kdialog | tail -n 1) \ --title \"$title\" --passivepopup \"$msg\" 3" fi

File /lib/udev/lvs-webcam.sh

#!/bin/sh find_display() { if [ -r "/proc/$1/environ" ] then perl -ne 'if ( /DISPLAY=([^:]+){0,1}(:\d+)(.\d+){0,1}/ ) { print "$1$2$3\n"; }' < /proc/$1/environ fi return 0 } user_loop() { OLD_DISPLAY=$DISPLAY ps -C kwrapper -C kwrapper4 h -o pid,user | while read pid user do grep -q ksmserver /proc/$pid/cmdline &> /dev/null || continue export DISPLAY=$(find_display $pid) su - $user -c "$1" done export DISPLAY=$OLD_DISPLAY unset OLD_DISPLAY sleep 1 } title="Webcam" msg="Webcam" case $ACTION in add) msg="$msg enabled" ;; remove) msg="$msg disabled" ;; esac user_loop "$(ls /usr/kde/*/bin/kdialog | tail -n 1) \ --title \"$title\" --passivepopup \"$msg\" 3"

Now every time you turn wifi/bluetooth/webcam on/off a notification will appear near KDE's notification tray icon:

Sager NP7652: finally

Yesterday, I finally got my Sager NP7652 laptop (Clevo W765CUH barebone) in my hands. The LCD was replaced and there is no dead pixels (so far). I copied my Gentoo installation from my old Acer Ferrari 4005 to it to avoid the loooooong process of installing Gentoo from the begining, also because my Internet connection is slow and it would take almost a week to download the source code for all ebuilds. The configuration (click on the image to see it completely):

ACPI

Battery

/proc/acpi/battery/BAT0/state does not show the "present rate", which prevents KDE's powerdevil to measure how much remaining time I still have. I had this problem with my Acer Ferrari 4005 too, a BIOS update solved the problem that time. Unfortunately Sager has discontinued this laptop, which was released less than six months ago, those notebook sellers must be kidding to discontinue a notebook so fast. So until I find a BIOS update to solve this problem I am using the kernel's CONFIG_ACPI_CUSTOM_DSDT feature to replace the BIOS's DSDT by one I have edited by hand. To use the new DSDT:

1. Download it
2. Enable  CONFIG_ACPI_CUSTOM_DSDT: make menu_config -> Power management and ACPI options -> ACPI (Advanced Configuration and Power Interface) Support -> Custom DSDT Table file to include. Select the downloaded file.
3. Compile and install the new kernel.
4. Reboot, that is it.

Here is the diff of the original DSDT.

Fans

The fans run at full speed since kernel boots up, but if you press the third hot key button (the one with a M surrounded by an elipse) the fans run quietly, this is called "silent mode". If you press it again the fans run at full speed again. OBS: the processor will *not* run at full power when in silent mode. OBS2: when using ATI proprietary drivers (ati-drivers ebuild) instead of the opensource drivers (xf86-video-ati ebuild) the fans run quietly.

Speedstep

Driver: acpi-cpufreq.ko.

I tried to use phc-intel to undervolt the CPU C-states but it did not work as expected. It seems this Core i7 620m CPU recognise the undervolt and automatically reduces CPU performance instead of allowing it to crash. Do not worry, the crash is part of the tweaking process to get the voltage values to configure the phc-intel module. I tried all values from 20 mW to 1 mV at 2667 MHz clock and the CPU did not crash but the performance decreased when compiling the kernel. Since this CPU has turbo mode capability I guess it is it that is automatically decreasing CPU performance to avoid the crash. The clock stayed at 2667 MHz, but compiling the kernel was much more slower using 1 mV than with 20 mW.

Suspend to Disk

I am using TuxOnIce for suspend to disk. To install it:

• Apply the patch against the kernel.
• Enable it  make menu_config -> Power management and ACPI options ->Enhanced Hibernation (TuxOnIce) -> File Allocator, Swap Allocator (if you have a swap partition), Userspace User Interface support and install the new kernel.
• Install pm-utils ebuild/package: emerge -v pm-utils
• Edit /etc/pm/config.d/gentoo and change the line with SLEEP_MODULE to SLEEP_MODULE="tuxonice". Now KDE's powerdevil plasmoid will use TuxOnIce to hibernate.

Sometimes some programs setfaults after resume (if one of them is the init program then system will crash). If I clean the swap space up (swapoff -a; swapon -a) before suspending then there is no segfault but that is damn slow if there several hundreds of MB in the swap file. Well, I tried a different approach and created a dedicated hibernate file that seems to also fix the problem and is pretty fast too, so do:

Configure Tux On Ice

# echo "TuxOnIce" > /hibernation-file # dd if=/dev/zero bs=1M count=2048 >> /hibernation-file # echo /hibernation-file > /sys/power/tuxonice/file/target # cat /sys/power/tuxonice/resume UUID=ea1d2e190cfe4901ac80645f47046980:0x56f8000

Change the resume kernel parameter to the new inode location:

Kernel parameter

resume=/dev/sda6:0x56f8000

Add the line below to /etc/hibernate/common.conf

/etc/hibernate/common.conf

ProcSetting file/target /hibernation-file

Bluetooth

Cambridge Silicon Radio bluetooth controller, driver: btusb.ko.

Card Reader

JMicron SD/MS Host controllers, Secure Digital driver: sdhci-pci.ko, Memory Stick driver: jmb38x_ms.ko. Tested with SD and MS PRO Duo cards. Not tested but should work as well: MS, MS PRO, MS Duo, Mini-SD, MMC and RS cards.

DVD Burning

Works as expected, at least when burning an iso image to a DVD-r media (8x speed).

Finger Print Reader

Works with fingerprint-gui 1.04, just execute the command below to avoid the error message "ABSOpen() failed -1086 (An internal error occurred (pt: tfmerr -1086).)":

mkdir -m700 /var/upek_data/

Hot Key Buttons

All buttons working:

1. E-mail.
2. Internet (Web Browser).
3. Toggle Silient Mode (for power saving). When enabled, Silent Mode will reduce fan noise and save power consumption. Note this may reduce computer performance.

I have configured udev to make show a KDE notification when the wifi, bluetooth or webcam is activated / desactivated. You can do the same for the silent hot key button using khotkey section in KDE's systemsettings, no need to go for udev.

Modem

Does not work yet: Re: AW: agere softmodem HDA + Intel Ibex Peak High Definition Audio

Sata and e-Sata

Intel Ibex Peak 4 port SATA AHCI controller, driver ahci.ko. To compile the driver: make menu config -> Device Drivers ->  Serial ATA and Parallel ATA drivers ->  AHCI SATA support

This is what I do before switching my e-Sata HD off:

1. umount all partitions.
2. echo 1 > /sys/block/sdb/device/delete

When issuing the last command the following lines appears in dmesg:

[40049.014691] sd 4:0:0:0: [sdb] Synchronizing SCSI cache
[40049.014851] sd 4:0:0:0: [sdb] Stopping disk
[40049.341191] ata5.00: disabled



You configure hald and udisks to thread "e-sata" disks as removable. Udisks is the default disk manager in KDE SC 4.6.x, so it is preferable.

Sound Card

Intel Ibex Peak HDA sound card, driver: snd-hda-intel.ko. Playback and internal microphone tested with Skype, all working. I moved my old /etc/asound.conf to /etc/asound.ferrari, it is not needed anymore because this sound card multiplex audio streamings without dmix alsa plugin. I do not have any s/pdif receiver so I cannot test it.

Just a side note: when the power save mode is enabled (echo 1 > /sys/module/snd_hda_intel/parameters/power_save) every time you change the volumes with a mixer or some program starts to play something there is a short crack sound in the speakers. It sounds even when all volume channels are mute or using earphone. That is annoying, so I prefer to disable the power save mode (echo 0 > /sys/module/snd_hda_intel/parameters/power_save).

USB

Intel Ibex Peak EHCI controller, drivers: ehci-hcd.ko and uhci-hcd.ko.

Video

ATI HD4570 video card, driver: xf86-video-ati-6.13.0, firmware: radeon-ucode-20100408. Working with KMS+DRI2, Googleearth and Kwin's composite effects work together too!!!. To use the firmware enable make menuconfig -> Device Drivers -> Generic Driver Options -> Include in-kernel firmware blobs in kernel binary. Then type "radeon/R700_rlc.bin" in "External firmware blobs to build into the kernel binary", copy /lib/firmware/radeon/R700_rlc.bin to /usr/src/linux/firmware/radeon/ and compile the kernel.

Relevant ebuilds (packages) I am using:

• kernel 2.6.33.4
• xf86-video-ati-6.13.0
• radeon-ucode-20100408
• xorg-server-1.8.1-r1
• mesa-7.8.2
• libdrm-2.4.19

Proprietary Driver (fglrx.ko)

Using ati-drivers ebuild brings one big advantage: the GPU runs cooler and the fans run quieter (as quiet as in Windows 7). I think it also helps with battery time, but I have not measure it. That only works as long as Xorg is running, if you to go the console (Ctrl+Alt+F1) the GPU fans start to run at full speed. Going back to Xorg makes them run quiter again. The 3D performance is noticeably better with ati-drivers.

One disadvantage in using ati-drivers is that you have to disable KMS (kernel modsetting) and the radeon kernel module. Otherwise the LCD gets blank when Xorg starts and you will have to restart the notebook to restore the video card to the correct state. Using composite (3D effects) while playing movies usually makes the movie flicker. To solve that problem DRI2 and KMS were created but since we cannot use KMS with ati-drivers I thought I would have to disable the 3D effects when using mplayer. Fortunately there is no flicker :-). In my old notebook (Ferrari 4005, ATI x700 card) the flickering is very annoying. I still own the Ferrari 4005, anyone here wants to buy a Ferrari notebook? :-) The battery still holds 72% of the original manufacturer capacity (around 3400 mAh) and everything works in Linux, accept the svideo port and the card reader, which does not read SD cards anymore, but reads Memory Stick (weird, hugh?) It comes with a bluetooth mouse too.

Unfortunately several important aticonfig commands do not work with this card:

evolucao ~ # aticonfig --adapter=0 --od-getclocks --od-gettemperature Adapter 0 - ATI Mobility Radeon HD 4500 Series Core (MHz) Memory (MHz) Current Clocks : 680 500 Current Peak : 680 500 Configurable Peak Range : [680-680] [500-500] GPU load : 0% ERROR - Get temperature failed for Adapter 0 - ATI Mobility Radeon HD 4500 Series

GPU load always stays at 0% and the thermal sensors are not compatible with aticonfig. Everest in Windows 7 is able to get the GPU temperature. As you can also notice the GPU and Memory clocks cannot be changed.

VGA Port

Works as expected. KDE has this beautiful and effecient kcm module to configure multiple monitors and it works great with the ATI HD4570:

HDMI Port

Work as expected (both video and audio). You need to configure /etc/asound.conf to route audio to the sound card that the video card (ati 4570) registers or use pulseaudio.

Webcam

BisonCam NB Pro webcam, driver: uvcvideo.ko. To compile the driver: make menu config -> Device Drivers -> Multimedia support -> Video capture adapters -> V4L USB devices -> USB Video Class (UVC)

Wired Ethernet

JMicron JMC250 gigabit ethernet PCI-e, driver jme.ko. To compile the driver: make menu config -> Device Drivers -> Network device support ->  Ethernet (1000 Mbit) ->  JMicron(R) PCI-Express Gigabit Ethernet support

Wireless

Intel WiFi Link 6000, driver: iwlagn.ko, firmware: iwl6000-ucode-9.193.4.1.

Gentoo Specific

In /etc/make.conf:

• CHOST="x86_64-pc-linux-gnu"
• CFLAGS="-O2 -march=core2 -pipe -fomit-frame-pointer -msse3 -msse4 -mcx16 -mpopcnt -msahf"
• LDFLAGS="${LDFLAGS} -Wl,-O1"
• VIDEO_CARDS="vesa radeon"
• ALSA_CARDS="snd-hda-intel usb-audio"

Symbolic link: /etc/make.profile -> ../usr/portage/profiles/default/linux/amd64/10.0/desktop/kde . It is ironic the fact that Gentoo use amd64 profile for an Intel processor.

File /etc/modules.autoload.d/kernel-2.6

microcode # for updating CPU's microcode acpi-cpufreq # for CPU frequency scaling cdc-acm # for my 3G modem fglrx # for the video card vboxdrv # for VirtualBox vboxnetflt # idem vboxnetadp # idem

All other drivers are automaticaly loaded by udev during boot initialization. Except for fglrx.ko and the three VirtualBox drivers (vboxdrv.ko, vboxnetflt.ko, vboxnetadp.ko) all other drivers are included in the vanilla Linux kernel. fglrx.ko is compiled by the x11-drivers/ati-drivers ebuild and the three VirtualBox drivers are compiled by the app-emulation/virtualbox-modules ebuild

Sager NP7652

My new notebook/laptop has arrived yesterday, unfortunately with one stuck pixel :-((((((((((((((((((((((((((((((((((((((((((((((((((((((( I have searched for ways to fix it, tried some things and it seems to be fixed now. The notebook is turned off now and I am using my old notebook (Acer Ferrari 4005). Honestly, I am with fear to turn the notebook on and see the dead pixel revived from the dead (or it would be from the living :-/). When I feel more relieved for solving this problem once and for all I will write a review/howto about how Gentoo Linux run on it. Update: as I feared when I turn the notebook on the stuck pixel is there again :-((((((((((((((((((((((((((((((((( Update2: today I have left the notebook to be sent back to Sager to replace the LCD, I do not stand that bright/stuck pixel. Let's see if Sager support is better than their quality control.

Meu novo notebook/laptop chegou ontem, infelizmente, com um stuck pixel :-((((((((((((((((((((((((((((((((((((((((((((((((((((((( Fiquei um tempão procurando maneiras para corrigí-o, tentei algumas coisas e parece estar consertado agora. O notebook está desligado agora e estou usando meu antigo notebook (Acer Ferrari 4005). Honestamente, estou com medo de ligar o notebook e ver o dead pixel ressuscitado dentre os mortos (ou seria dentre os vivos :-/). Quanto estiver mais aliviado em resolver esse problema de uma vez por todas vou escrever uma avaliação/howto sobre como o Gentoo Linux roda nele. Atualização: como eu temia quanto eu ligo o notebook o stuck pixel está lá novamente :-(((((((((((((((((((((((((((((((((( Atualização 2: hoje eu dexei o notebook para ser enviado de volta para a Sager para trocar o LCD, eu não suporto aquele pixel brilhante. Vamos ver se o suporte da Sager é melhor do que o controle de qualidade deles.

Future Acquisition / Futura Aquisição: SAGER NP7652

Very interesting this new Sager NP7652 notebook. It has almost all those things I like in my current notebook (Acer Ferrari 4005) and very good price. The only things I would lose compared to F4005 would be: one less USB port, one less speed button, no expansion port, no DVI, no S-video, no infra-red and no fireware ports. Well, I would only miss the USB and S-video ports, the other ones are not that usefull anyway (I have never used the expansion and firewire ports, and have used the DVI and infra-red only for testing). I just would like to have the option to buy faster memory (1066 MHz is good, but I would like to buy 1333 MHz instead). In the future I will probably buy a USB 3.0 express card to have two more USB ports. More info about this notebook, including videos and benchmarks.

Muito interessante este novo notebook Sager NP7652. Ele tem quase todas as coisas que eu gosto no meu notebook atual (Acer Ferrari 4005) e um ótimo preco. As únicas coisas que eu perderia comparado com o F4005 seriam: uma porta USB a menos, um botão de atalho a menos e portas de expansão, DVI, S-video, infra-vermelho e firewire. Bem, I sentiria falta das portas USB e S-vide, as outras nem tanto (nunca usei as portas de expansão e firewire, e só usei DVI e infra-vermelho para testes). Gostaria de ter a opção de comprar memórias mais rápidas (1066 MHz é bom mas gostaria de comprar 1333 MHz). No futuro devo comprar um cartão express USB 3.0 para ter duas portas USB a mais.
