Solving issues in NetBSD

ACPI sub-system

The Lenovo IdeaPad S10-3t does not power off

There seem to be issues with the ACPI sub-system, the most obvious one while attempting to turn off the computer:

# shutdown -p now

which simply doesn't work. The kernel mentions "acpi0: entering state 5" and then locks.

The issue is apparently broader, with "envstat -r" being, at best, extremely slow.

Booting

The system is unstable when booting with genfb

Up until 6.0_BETA booting with genfb (either with or without a splash screen) was very unreliable, and X not starting at all. Since shortly before the netbsd-6 branch it seems to work properly.

However:

• the colours and/or the logo are usually wrong or corrupted;
• not every colour depth seems supported on every graphics card;
• the kernel sometimes still outputs some text before enabling the splash screen.
  

Graphics sub-system

The graphics card on the Lenovo IdeaPad S10-3t is not accelerated

This problem is currently being addressed by Gregoire Sutre, on his netbsd-drmgem branch on github: https://github.com/gsutre/netbsd-drmgem.

Software acceleration is buggy with modular-xorg-server

Using modular-xorg-server with the "vesa" driver (while the accelerated Intel driver gets fixed) is barely usable, as windows are not fully drawn correctly. Running xterm with anti-aliased fonts is an easy way to reproduce the issue.

It seems to be related to acceleration issues rather than a specific video driver, maybe when no DRI driver could be loaded. I have yet to determine if both EXA and XAA exhibit the issue.

Also noteworthy is the requirement for the Xorg executable to be linked with libpthread for the DRI modules to load correctly.

Multimedia support

The sound card on the Lenovo IdeaPad S10-3t does not work

The sound card on the Lenovo IdeaPad S10-3t fails to attach correctly, with the following error:

hdaudio0 at pci0 dev 27 function 0: HD Audio Controller
hdaudio0: interrupting at ioapic0 pin 22
hdaudio0: timeout stopping RIRB
hdaudio0: couldn't reset because RIRB is busy
hdaudio0: device driver failed to attach

The root cause of this problem is currently unknown.

The webcam on the Lenovo IdeaPad S10-3t does not work

The webcam on the Lenovo IdeaPad S10-3t is detected and should be functional, however reading it with mplayer locks the machine with a 6.0_BETA kernel:

$ mplayer -tv driver=v4l2 tv://

Touchscreen

The wstablet framework must be updated (and merged)

The wstablet framework was being worked on as part of a Google Summer of Code project in August 2008, see http://netbsd-soc.sourceforge.net/projects/wscons/.

Unfortunately, it seems that the results of this project have not been merged to NetBSD, nor significant enough to be useful for touchscreen integration here. This issue is therefore closed.

The touchscreen on the Lenovo IdeaPad S10-3t is not supported

This is no longer an issue, as:

• the uts(4) driver was written, submitted and integrated upstream (PR/45850)
• the xf86-input-mouse driver was patched for supporting absolute coordinates (PR/45853)
  
• the tpcalib and wscons framework was debugged and extended (PR/45872)

• no longer require root privileges for calibrating the screen;
  
• automate calibration when changing screen sizes.
  

Wireless support

The wireless card on the Lenovo IdeaPad S10-3t is not supported

The Lenovo IdeaPad S10-3t has an Atheros wireless card, which fails to attach with the following error:

ath0 at pci2 dev 0 function 0: Atheros 9285
ath0: interrupting at ioapic0 pin 17
ath0: unable to attach hardware; HAL status 3

The root cause of this problem has not been identified yet.
