01:56 <MoeIcenowy> anarsoul: strange

01:56 <MoeIcenowy> the GPU quirk of chromium changed to "Mali-4xx on Linux does not support GL_RGB format"

01:56 <MoeIcenowy> originally it has no "on Linux"

01:57 <MoeIcenowy> (and a os type restriction of "linux" is also introduced)

02:01 <MoeIcenowy> https://chromium-review.googlesource.com/c/chromium/src/+/1891139

02:37 <anarsoul|c> Feel free to RE it on android :)

05:48 <anarsoul> MoeIcenowy: I don't think that mali4x0 can render to GL_RGB

05:48 <anarsoul> it can sample from it though

05:48 <anarsoul> (and we expose that)

05:52 <anarsoul> see https://www.khronos.org/opengl/wiki/Common_Mistakes

05:52 <anarsoul> "Texture upload and pixel reads"

05:52 <anarsoul> I'm not sure why chromium devs used GL_RGB in first place

06:32 <MoeIcenowy> anarsoul: is it possible that blob on Android fakes GL_RGB with GL_RGBA ?

06:33 <anarsoul> maybe

06:33 <anarsoul> that'd require converting RGB to/from RGBA or RGBX when uploading or downloading buffers

06:34 <MoeIcenowy> then should I just change this "on Linux" entry to suite lima

06:34 <MoeIcenowy> or introduce a standalone entry for lima, regardless of OS?

06:35 <anarsoul> I asked #dri-devel whether it's possible to emulate GL_RGB in mesa, let's wait for response

08:32 <MoeIcenowy> anarsoul: by the way, renderonly seems to be not behaving well when facing memory pressure

08:33 <MoeIcenowy> it says DRM_IOCTL_MODE_CREATE_DUMB failure

08:33 <MoeIcenowy> for example, when I'm running chromium and opened a number of pages

16:14 <anarsoul> MoeIcenowy: you likely need more CMA

16:49 <inode> i have mainline linux 5.4 running on rk3229, which supossedly features a mali-400 gpu... i've built libdrm, mesa (from master), glmark2-es2, and xorg - yet if i make use of anything that involves libEGL like glmark2-es2-drm or Xorg's modesetting with glamor enable - the system locks up and i receive kernel messages about rcu_shed detecting stalls, and NMIs fired for seemingly unresponsive cores

16:49 <inode> and before this, libEGL says "libEGL debug: EGL user error 0x3001 (EGL_NOT_INITIALIZED) in eglQueryString"

16:50 <inode> does anyone have any ideas about what may be wrong?

21:18 <anarsoul> inode: I'm not sure where rcu_sched stalls are coming from, but I'd suggest to check whether you have CPU and/or GPU voltage set correctly

21:18 <anarsoul> lima doesn't configure it atm, so you have to make sure that initial values are good for GPU to work

21:19 <inode> thanks, i'll try to confirm that they match what the vendor's kernel happens to use

21:20 <anarsoul> also check operating points for CPU

21:47 <anarsoul> MoeIcenowy: can you check whether https://gist.github.com/anarsoul/2ae11dcac3fffbe429ec3eb6cda40edd fixes chromium issue for you?
