MSM/QSD hardware adaptation

This page was inspired by this link http://www.android-devs.com/?p=152 which has instructions to run Debian natively on the Google Nexus One handset. With a number of vendors shipping kernel source with MSM/QSD hardware this gives the possibility of running MeeGo on these platforms. As usual open drivers will be key to success.

This port is not a work in progress and not meant for end user installation. The following details are for MSM/QSD porting effort and no end user images are available.

See details of how to start developing for your device here, http://android.modaco.com/category/363/device-specific/

Nexus One

Initial Port

basic msm_fb with mesa

The picture above was taken with the 18.09.10 daily trunk handset UX, mesa packages added to provide swrast-DRI, ELG and GLESv2. Kernel is a stock google 2.6.32 msm kernel. Touch is working but needs rotating.

libEGL and libGLESv2

As we know vanilla X and software GLES works but we need hardware libEGL and libGLESv2 for better performance.

I pulled libEGL.so, libGLESv2.so and libGLESv1_CM.so from my Nexus /system/lib along with the supporting /system/lib/egl files lib***_adreno200.so as the system/lib files are just stubs into the lib/egl files.

After booting .xsession_errors reported liblog.so not found when loading mcompositor. pulled that from Nexus.

libcutils.so was not found next then 'libc.so ELF version does not match current version' was reported. The libc.so in /usr/lib was a pointer to /lib so I just copied the /lib file to /usr/lib.

Now libutils.so and libz.so were not found and were pulled from the nexus.

Now here is the kicker, 'undefined Symbol __sF' in libc.

This is because the Android libs I pulled have been built with Bionic libc and I cannot use that as that would break the rest of MeeGo.

So the question is can we arrange for bionic and glibc to coexist or is this the end of the road?

After talking to a few guys on xda I think this avenue is closed - unless you know better. http://forum.xda-developers.com/showthread.php?t=764255&page=6

UPDATE : http://www.imxdev.org/wiki/index.php?title=All_Boards_3D_Graphics, it seems the mx51 has the same GPU

Just had this email in from Jordan Crouse at code Auroroa when I asked if the drivers above were the best to use on the Nexus :(

You have the correct X driver and kernel driver.   That should give you some limited blit acceleration on on the Nexus One for 2D rendering.
Unfortunately, the parts you really need are the proprietary 3D drivers, and those are not available anywhere.  Without those, you'll be stuck
with software 3D for the long haul.  Sorry.

Such a shame (vgrade)

Dell Streak

From smoku on #meego-arm

• Kernel
  • Streak Kernel Release from Dell - http://opensource.dell.com/releases/streak/
  • Kernel fixed for building for normal Linux distribution - http://gitorious.org/streak/kernel
  • kernel-streak RPM package - http://download.obs.maemo.org/home:/smoku/MeeGo_current/

• InitRD
  • File:Initrd.cpio.gz - INITial RamDisk booting Linux from /dev/mmcblk1p2

To create boot.img using this image use mkbootimg binary from Android Froyo Google tree:

 ./mkbootimg --kernel $KERNELIMAGE --ramdisk initrd.cpio.gz --base 0x20000000 -o boot.img

MSM XOrg driver

• MSM framebuffer driver is not working with X.Org fbdev driver. (Needs kernel thread patch to flush framebuffer data to display)
• MSM X.Org driver
  • xorg-x11-drv-msm RPM package - http://download.obs.maemo.org/home:/smoku/MeeGo_current/armv7l/

BlueTooth

Qualcomm BTS BlueTooth device is connected using USB UART which device is accessible as /dev/ttyS1. It requires firmware to be loaded before using. The hciattach was theoretically patched to allow Qualcomm firmware loading. But it does not work on Streak. The hciattach just timeouts.

 # modprobe hci_uart
 # hciattach ttyS1 qualcomm

HTC Desire

Using a modified version of the N900 Acceptance Image.

• Charging works (and the charging symbol moves), Battery Status doesn't show though when the charger is out.
• adbd works

-Termana

GPRS

Note: This procedure should work for all MSM and QSD based devices, HOWEVER I have only tested it on the Desire - Termana

The Desire's modem can be communicated with through two dev nodes - /dev/smd0 and /dev/qmi0.

/dev/smd0 is the main part and communicates using AT commands plus additional proprietary non-standard Qualcomm AT commands.

/dev/qmi0 is the second part and it communicates using a proprietary Qualcomm protocol.

Replace /etc/ofono/modem.conf with this: http://dl.dropbox.com/u/13630837/modem.conf

Then you can use the following commands to bring up a data connection on MeeGo:

echo -e "AT+CGDCONT=1,\"IP\",\"APNHERE\",\"\",0,0\r" > /dev/smd0

echo -e 'ATD*99***1#\r' > /dev/smd0

echo -n 'up:APNHERE "" ""' > /dev/qmi0

dhclient rmnet0
