Compiling weston

Hi,

This probably has been discussed before, but I couldn't find anything from archives or from google other than it seems some have gotten this working.

I'm compiling Weston/wayland based system for imx6q-sdb - develboard.

In local.conf I have:
DISTRO_FEATURES_append = " wayland opengl"

In image-recipe I have:

REQUIRED_DISTRO_FEATURES = "wayland"

CORE_IMAGE_BASE_INSTALL += "weston weston-init weston-examples gtk+3-demo clutter-1.0-examples libwayland-egl libwayland-egl-dev"

The built is stopped at error:

| configure: error: Package requirements (egl >= 7.10 glesv2 wayland-client wayland-egl) were not met:
|
| No package 'wayland-egl' found

The  libwayland-egl and libwayland-egl-dev were added later, but the same error still stays.

Should Weston compile without any modifications after checking out meta-fsl-arm?

I tried also checking out the meta-fsl-bsp-release which has newer Weston version and other packages. That worked even worse since the patches provided wouldn't apply to that version.

So how have anyone gotten Weston/wayland compiled?

Hi Teemu,

Adding Wayland isn't enough. You should also explicitly remove X11 and Framebuffer so the right Vivante GPU driver gets included for Wayland/Weston.

Try again in new build folder and add this line to your local.conf:
DISTRO_FEATURES_remove = "x11 directfb"

These slides are for fsl-release-bsp, but most parts applies also for fsl-community-bsp, so check slide 49:
https://community.freescale.com/docs/DOC-104266

Heikki Sarkanen

Add:

DISTRO_FEATURES_remove = "x11"

and it should work.

Hi,

Thanks. I got the wayland/Weston compiled with that! Thanks.

This next piece is bit of off-topic, but I'm sure someone doing this maybe end up having same problem.

I have display connected to connector marked LVDS0. I got the picture to it with X11 when I configured the screen being at /dev/fb4. Problem is that I'm not sure how to configure that in Weston. I created /.config/weston.ini (I checked that $HOME is set to / when Weston is being started) with output configured to LVDS0 and resolution being correct, but that didn't help. Debugging is also bit hard because Weston does not output anything. I can see that it's running (Weston-processes), but that's about it.

So couple questions. Where should I put the Weston.ini and how do I turn on the debug/info from Weston?

Hi,

As I have understood on current iMX6/Yocto you are forced to use fbdev-backend, which doesn't really use weston.ini until lately (possibly included in coming Weston 1.8) http://cgit.freedesktop.org/wayland/weston/commit/?id=44ed70b469beb97b6438d07a8048418f6302a0e2 when transform was added. Drm-backend supports many configs but currently iMX6 doesn't support it. Of course you can change desktop-shell behavior etc if you wish using ~/.config/weston.ini but that's another topic. But things you're trying to do should be possible.

You can check command line options supported by fbdev-backend from Weston sources: http://cgit.freedesktop.org/wayland/weston/tree/src/compositor-fbdev.c?id=1.6.0#n971 Fsl-patch adds option for gal2d-renderer which I found having some graphics glithces which default gl-renderer doesn't have: https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-graphics/wayland/weston/0002-ENGR00314805-2-Add-Vivante-GAL2D-support.patch#L256-L257

So changing the device should be easy:
# Kill the already running Weston
killall weston
# Weston wants this environment variable to be set (http://wayland.freedesktop.org/building.html)<http://wayland.freedesktop.org/building.html>
export XDG_RUNTIME_DIR=/run/user/root && mkdir --parents $XDG_RUNTIME_DIR && chmod 0700 $XDG_RUNTIME_DIR
# Launch Weston on fb4, you should now see some debug info as well
weston --tty=1 --use-gal2d=0 --use-gl=1 --device=/dev/fb4

If you want to change the behavior on boot you should look Weston init file: https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-graphics/wayland/weston-init/init You could try to change line "openvt -s weston" to something like "openvt -s -- weston --device=/dev/fb4".

Heikki Sarkanen

Hi,

I got the debug-output. It seems that the Weston init-script opens virtual terminal and I think that's where all the outputs are but they are not just shown now.

One more problem. It seems that the Weston always defaults to 1024x768 resolution. I looked at the compositor-fbdev.c code you pointed out and it seems that there is no option for configuring the resolution or screen settings. I tried to set the parameters with fbset and they seemed to be right before I started the Weston, but still the Weston defaults to 1024x768 resolution.  I'm guessing there has to be a way to configure the resolution/color depth etc.?

Although looking at the code I get feeling that they are calculated runtime from framebuffer metadata.

Hi,

In my experience the screen should be configured properly for the kernel after that I haven't had any problems in Weston to recognize the resolution.

First you could try to pass it as kernel command line option, for example: "video=mxcfb0:dev=ldb,1280x800M@60,if=RGB24 ldb=sin0". More info: http://boundarydevices.com/configuring-i-mx6-machines-different-screens-nitrogen6x-sabre-lite/​

For more permanent configuration you could try modifying device tree, format and device tree support may vary depending on your kernel version. Here is one example: https://github.com/Freescale/meta-fsl-arm-extra/blob/master/recipes-kernel/linux/linux-compulab-3.14.28/0054-ARM-i.MX6-dts-add-ldb-support-for-SBC-FX6-boards.patch

As I have understood on current iMX6/Yocto you are forced to use fbdev-backend, which doesn't really use weston.ini until lately (possibly included in coming Weston 1.8) http://cgit.freedesktop.org/wayland/weston/commit/?id=44ed70b469beb97b6438d07a8048418f6302a0e2 when transform was added. Drm-backend supports many configs but currently iMX6 doesn't support it. Of course you can change desktop-shell behavior etc if you wish using ~/.config/weston.ini but that's another topic. But things you're trying to do should be possible.

You can check command line options supported by fbdev-backend from Weston sources: http://cgit.freedesktop.org/wayland/weston/tree/src/compositor-fbdev.c?id=1.6.0#n971 Fsl-patch adds option for gal2d-renderer which I found having some graphics glithces which default gl-renderer doesn't have: https://github.com/Freescale/meta-fsl-arm/blob/master/recipes-graphics/wayland/weston/0002-ENGR00314805-2-Add-Vivante-GAL2D-support.patch#L256-L257

So changing the device should be easy:
# Kill the already running Weston
killall weston
# Weston wants this environment variable to be set (http://wayland.freedesktop.org/building.html)<http://wayland.freedesktop.org/building.html>
export XDG_RUNTIME_DIR=/run/user/root && mkdir --parents $XDG_RUNTIME_DIR && chmod 0700 $XDG_RUNTIME_DIR
# Launch Weston on fb4, you should now see some debug info as well
weston --tty=1 --use-gal2d=0 --use-gl=1 --device=/dev/fb4

If you want to change the behavior on boot you should look Weston init file: https://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/recipes-graphics/wayland/weston-init/init You could try to change line "openvt -s weston" to something like "openvt -s -- weston --device=/dev/fb4".

Heikki Sarkanen

Hi,

Thanks. I got the wayland/Weston compiled with that! Thanks.

This next piece is bit of off-topic, but I’m sure someone doing this maybe end up having same problem.

I have display connected to connector marked LVDS0. I got the picture to it with X11 when I configured the screen being at /dev/fb4. Problem is that I’m not sure how to configure that in Weston. I created /.config/weston.ini (I checked that $HOME is set to / when Weston is being started) with output configured to LVDS0 and resolution being correct, but that didn’t help. Debugging is also bit hard because Weston does not output anything. I can see that it’s running (Weston-processes), but that’s about it.

So couple questions. Where should I put the Weston.ini and how do I turn on the debug/info from Weston?

Hi Teemu,

Adding Wayland isn't enough. You should also explicitly remove X11 and Framebuffer so the right Vivante GPU driver gets included for Wayland/Weston.

Try again in new build folder and add this line to your local.conf:
DISTRO_FEATURES_remove = "x11 directfb"

These slides are for fsl-release-bsp, but most parts applies also for fsl-community-bsp, so check slide 49:
https://community.freescale.com/docs/DOC-104266

Subject: [meta-freescale] Compiling weston

Hi,

This probably has been discussed before, but I couldn’t find anything from archives or from google other than it seems some have gotten this working.

I’m compiling Weston/wayland based system for imx6q-sdb – develboard.

In local.conf I have:
DISTRO_FEATURES_append = " wayland opengl"

In image-recipe I have:

REQUIRED_DISTRO_FEATURES = "wayland"

CORE_IMAGE_BASE_INSTALL += "weston weston-init weston-examples gtk+3-demo clutter-1.0-examples libwayland-egl libwayland-egl-dev"

The built is stopped at error:

| configure: error: Package requirements (egl >= 7.10 glesv2 wayland-client wayland-egl) were not met:
|
| No package 'wayland-egl' found

The  libwayland-egl and libwayland-egl-dev were added later, but the same error still stays.

Should Weston compile without any modifications after checking out meta-fsl-arm?

I tried also checking out the meta-fsl-bsp-release which has newer Weston version and other packages. That worked even worse since the patches provided wouldn’t apply to that version.

So how have anyone gotten Weston/wayland compiled?

Hi,

Ah, forgot the whole command line options. Now I have picture! Thanks. Now I just need to make that patch for the display settings.

Hi,

In my experience the screen should be configured properly for the kernel after that I haven't had any problems in Weston to recognize the resolution.

First you could try to pass it as kernel command line option, for example: "video=mxcfb0:dev=ldb,1280x800M@60,if=RGB24 ldb=sin0". More info: http://boundarydevices.com/configuring-i-mx6-machines-different-screens-nitrogen6x-sabre-lite/​

For more permanent configuration you could try modifying device tree, format and device tree support may vary depending on your kernel version. Here is one example: https://github.com/Freescale/meta-fsl-arm-extra/blob/master/recipes-kernel/linux/linux-compulab-3.14.28/0054-ARM-i.MX6-dts-add-ldb-support-for-SBC-FX6-boards.patch

Hi,

I got the debug-output. It seems that the Weston init-script opens virtual terminal and I think that’s where all the outputs are but they are not just shown now.

One more problem. It seems that the Weston always defaults to 1024x768 resolution. I looked at the compositor-fbdev.c code you pointed out and it seems that there is no option for configuring the resolution or screen settings. I tried to set the parameters with fbset and they seemed to be right before I started the Weston, but still the Weston defaults to 1024x768 resolution.  I’m guessing there has to be a way to configure the resolution/color depth etc.?

Although looking at the code I get feeling that they are calculated runtime from framebuffer metadata.
