Hi Rob,
Thank you very much for information. Actually I am not constrained to
use X server.
But can you please let me know what are the components that may be
needed for testing freedreno test applications, apart from libdrm and mesa?
I thought X may be needed for graphic drawing.
Sorry if the questions are too basic. Actually I am getting overwhelmed
with lot of options available and I am not getting what is the right way
to proceed...
I will try get something to work with GBM though
Regards,
Abhijit

Hi All :)
Finally I am able to get freedreno_drv.so and xserver ABI version to get
matched.
I am using buildroot to get the proper package dependency and build.
Currently our target has following binaries,
$(ROOT_DIR)/usr/lib/xorg/modules/drivers/freedreno_drv.so
$(ROOT_DIR)/usr/lib/dri/msm_dri.so
$(ROOT_DIR)/usr/lib/libdrm_freedreno.so
I also loaded msm_kgsl_core.ko and msm_adreno.ko
But my xinit is giving following output
"[ 233.794] (WW) Falling back to old probe method for freedreno"
"[ 233.831] (II) No msm DRM/KMS, fallback to fbdev/kgsl"
I guess that it is failing to find the old kgsl shim drm driver, which
enabled allocation of GEM buffers for pixmaps. I know Wladimir played
a bit with this on imx5, but I think he was just using gbm/kms and not
x11. I guess he was using imx-drm for GEM buffer allocation?

"[ 234.801] (II) UnloadModule: "freedreno""
"[ 234.801] (II) Unloading freedreno"
Referring to freedreno architecture, I interpreted kgsl must be enabled in
the libdrm and enabled same. But still freedreno module is getting unloaded
I will be grateful if any body can give lead on this.

Abhijit

Hi all,
Running xinit load freedreno_drv.so file after adding configuration in
/etc/X11/xorg.conf,
Section "Server Flags"
Option "IgnoreABI"
EndSection
Section "Device"
Identifier "Device0"
Driver "freedreno"
VendorName "Freedreno "
BoardName "SoC"

But I am getting segmentaion fault and following is snippet of
/var/log/Xorg.0.log

Fatal server error:
[ 6587.059] Caught signal 11 (Segmentation fault). Server aborting
Please let me know how I can go about debugging it
well, IgnoreABI is more than a bit scary.. the old downstream msm
fdbdev driver wasn't a bit non-standard, so there might be issues w/
xf86-video-freedreno working w/ a different fbdev driver (not to
mention the non-KMS codepaths probably haven't been exercised in a
while). But I suspect an ABI mismatch between xf86-video-freedreno is
likely to cause more problems.

Hi Ilia,
Thank you very much for your reply.
I am able to create msm_dri.so file with options you provided
Even after that, soft pipe is being used for rendering.
I am suspecting that glxinfo will use driver depending on _drv.so being
detected by xinit
Now I have freedreno_drv.so too. But still soft pipe is being used. I am
trying to solve this puzzle.
Warm Regards,
Abhijit

I ensured that --enable-freedreno-kgsl is enabled in libdrm build and
the
same is copied to target
The issue seems to be in mesa build
I observed that there are two mechanism in which application can
interact
with underlaying DRM,
1. With DRI ($MESA_INSTALL_PATH/src/mesa/drivers/dri)
2. With Gallium driver ($MESA_INSTALL_PATH/src/gallium/drivers)
Freedreno driver is present only in Case 2. For that reason I
disabled dri
in Mesa build and enabled gallium-xlib intreface, which will enable
case 2
You absolutely need --enable-dri. Gallium drivers are also DRI
drivers. The "src/mesa/drivers/dri" drivers are "classic" drivers,
while the others are "gallium" drivers. However they're all DRI
drivers.
You can build mesa --with-dri-drivers=""
--with-gallium-drivers="freedreno", but you have to leave DRI(3)
enabled.
