Hi,
I used the option --subject-prefix="PATCH libdrm"
but it did not go as expected.

Anyway, the patch is for Android build of mesa/drm

This is probably a good idea!

Re: [PATCH] android: libdrm_platform: add liblog shared dependency

[Robert Foss]

On a second note, this does not apply on libdrm/master due
to:

LOCAL_SHARED_LIBRARIES := \
	libcutils

My thinking is that libcutils probably can be replaced with liblog,
but I'm not 100% sure.

Sorry, we have an additional Google patch, not present in libdrm/master
that adds libdrm_platform module, but it is for a specific Google issue. [1]

However with libdrm module we have both liblog and libcutils shared dependencies

Do you know if [1] causes incompatibility issues with earlier android verions?
If not I would suggest upstreaming it too.

Re: [PATCH] android: libdrm_platform: add liblog shared dependency

[Tapani Pälli]

It seems like there is no usage of __android_log_vprint in upstream 
libdrm. Perhaps this was against libdrm with some android specific 
changes on top?

I used those patches to build with nougat-x86 and there was no issue.

To be precise I did a double rookie mistake, because __android_log_vprint
not used in upstream libdrm and libdrm_platform not used either.

Now starting from my mistakes, let's see if there is anything useful
to libdrm project

In our builds Chih-Wei Huang said that libdrm_platform is not used,
meaning not added to packages list,
however with oreo-x86 the build error appeared and the liblog dependency.

 __android_log_vprint is used with __ANDROID__ braces
in a special patch [2] by Chih-Wei Huang which adds capability to print logs
in logcat

If it's not too invasive in libdrm, it could be useful.
Cheers
Mauro

[2] Seems like a good idea to me.
Logcat really is the only intended path for logging on Android, and redirecting 
our logs there does make sense to me.

But, I'm not sure about I like the way [2] disregards log-levels in drmMsg().

Yeah, I think it's a good idea. I see that in mesa we include 
"android/log.h", not "log/log.h", will need to make sure we get that 
correctly, maybe older versions did "log/log.h"?

I would also be in favour of adding logcat support to libdrm.

Mauro, please respin when you have the time.

Hi,

I can try replacing <log/log.h> with <android/log.h>,
but I would like to get confirmation from Chih-Wei, the original author of [1]

Re: [PATCH] android: libdrm_platform: add liblog shared dependency

[Mauro Rossi]

Hi Emil, Chih-Wei,

what about the series of latest three patches we have in oreo-x86 branch?

[oreo-x86 branch]
http://git.osdn.net/view?p=android-x86/external-libdrm.git;a=history;f=Android.mk;h=f832b24e99007c75ce3a8d9a3ece34d4e475e957;hb=refs/heads/oreo-x86

My doubt is about the one "android: make libdrm*.so available to the
vendor partition",
should we keep it (and send to mesa/drm) so that we will simply have
our x86 branches aligned to mesa/drm,
or should we skip it in both cases?

Once this is assessed I will either send the series of 3 or just the
android logging one.
Mauro

Here is patch using include <android/log.h>
which should suffice for the purpose.

Re: [PATCH] android: libdrm_platform: add liblog shared dependency

[Chih-Wei Huang]

Sorry for the late reply since I didn't notice it.
(I rarely read the ML)

The patch of Jiyong Park is the one he submitted to the ML before.
https://patchwork.kernel.org/patch/9864539/
https://patchwork.kernel.org/patch/10109599/

I'm not sure why it's not merged. Maybe just forgotten.

The 2nd and 3rd patch (mine and Mauro's) could be combined
into one before submission, I think.
