This is WIP

Status

Install

• Download nemo-armv7hl-pandaboard-rnd.ks
• build image with:

mic cr raw nemo-armv7hl-pandaboard-rnd.ks --outdir=tmp/ --tokenmap=MER_RELEASE:latest,NEMO_RELEASE:latest,FLAVOUR:devel --arch=armv7hl --pkgmgr=zyp

Solved issues

• OpenGL app crash with SGX: launching an app works first time, but all subsequent attempts fail. Same cause: https://bugs.launchpad.net/linaro-ubuntu/+bug/1034178
• Full Nemo installation, after lock screen comes up, fails with:

Xorg invoked oom-killer: gfp_mask=0x44d0, order=2, oom_adj=0, oom_score_adj=0
full log: http://pastie.org/5668605

Less important:

• Moving mouse too early in in Xorg's boot, renders it unmovable - reconnect the cable
• 15/1/2013 FIXED: When mouse cursor is shown, any animation is flickering when mouse is moving
• 11/1/2013 WORKAROUNDED: Impossible to launch qmlcalc twice (or flickr-qml thrice), this what's spat (and qmlcalc dies):

[  121.403869] omapdrm omapdrm.0: already a pending flip

• 11/1/2013 FIXED: Currently, launching any OpenGL app (tested with flickr-qml, qmlcalc and duicontrolpanel) from within lipstick kills Xorg while applauncherd is boosting it for Qt+GLES. Fix: http://www.hastebin.com/notadehohi.coffee

Progress log (newest first)

• 15/1/2013 (sledge) OpenGL app crash with SGX: Jake9xx gave a tmp workaround http://pastie.org/5669270 , but it does not work
• 11/1/2013 (sledge) OpenGL app crash with SGX: looking into qmlcalc launch issues. flickr-qml also spits same old

[   54.713897] flickr-qml (214): /proc/214/oom_adj is deprecated, please use /proc/214/oom_score_adj instead.

and now also

[   57.826049] omapdrm omapdrm.0: already a pending flip

but does not crash. Xorg does not crash either (thanks to the previous fix)

qmlcalc also spits oom and "already a pending flip" however crashes (after first successful launch though!), more clues from the app booster stage:

Jan 11 16:56:28 localhost lipstick[201]: Found EGL_KHR_image_pixmap & GL_OES_EGL_image extensions (preferred method)!
Jan 11 16:56:28 localhost lipstick[201]: virtual WindowInfo::~WindowInfo() Destroyed windwo for  6291601
Jan 11 16:56:29 localhost mcompositor[200]: PVR:(Error): ReleaseImageFromTexture: Unsupported pixel format [207, /eglimage.c] (x3 times repeated)
Jan 11 16:56:29 localhost applauncherd[199]: Boosted process (pid=212) was terminated due to signal 11
Jan 11 16:56:29 localhost invoker[264]: error: Can't send signal 11 to application [212]: No such process

• 11/1/2013 (sledge) TODO: what causes out of memory? Reduce full Nemo installation package-by-package, irrelevant (GSM-related etc) ones first
  • Apparently, having on top of minimal-lipstick installed meegotouch-systemui (with its deps), it's triggering OOM (itself or one of its deps: connman-qt contextkit-plugin-cellular contextkit-plugin-connman libiodata libiphb libqmlog qmsystem timed tzdata-timed)

Installation

Full Nemo install is not working. In most boots it ends up running out of memory: Xorg rapidly increasing in memory usage, reaching 800MB in ~5seconds, and everything dies.

minimal-lipstick

A reduced Nemo installation, which works:

• mic create this: mer-minimal-lipstick-pandaboard-armv7hl.ks
  • It will load minimal lipstick, which works fine and accelerated and smooth! (Don't be offput by black/transparent lockscreen).
  • It's kernel: linux-ti-omap4-3.4.0; pvr-omap4-1.9.0.5.1.1; xorg-video-omap-git-a6b36b367b1b917d843cd2bc504ae8c466d5a29f (with the Xorg avoid crash patch http://www.hastebin.com/notadehohi.coffee )
