14:00 <narmstrong> robmur01: here is a dEQP run with info/err log level on the S912 T820 https://termbin.com/cpay

14:01 <narmstrong> with a huge amount of DATA_INVALID_FAULTs

14:06 <robmur01> narmstrong: hmm, the translation faults seem more concerning - does that have the kernel fixes? (now just waiting for Joerg to pick up and send on to Linus)

14:06 <narmstrong> robmur01: yep it has the fixes

14:10 <robmur01> hmm, so where are those wild reads coming from?

14:10 <narmstrong> here is the tree https://github.com/superna9999/linux/tree/amlogic/v5.3/panfrost

14:11 <robmur01> in fact the ones from 18s can't even be valid addresses from the 4GB mm since they have bit 32 set

14:24 <robmur01> do any other tests run OK on that same setup? I'm watching glmark run on my T820 right now; no page faults :/

14:26 <narmstrong> ok: 16025, warn: 64, bad: 1271, skip: 111, total: 17439 on the full dEQP run

14:26 <narmstrong> https://gitlab.freedesktop.org/narmstrong/mesa/-/jobs/679

14:30 <robmur01> I'd have to guess that there's something in the command stream etc. for those particular jobs that sends T820 off the rails

14:31 <robmur01> the "is this address near a known BO" thing would sure be useful to dissect those faults further :)

14:39 <robmur01> ...and now it hit the drm_sched_increase_karma crash. Have we fixed that yet? I've lost track.

14:43 <narmstrong> robmur01: I'm using steven's proposal patch, and it works fine (~25 dEQP runs without a crash except the first run)

14:44 <mrfixit2001> Hey there all :) I'm wanting to test panfrost. I've build mainline 5.4-rc and the latest mesa commit but I'm getting a "No OpenGL support in video driver" when I try and use it. Here's my config flags. Any advice? Maybe I shouldn't be using the bleeding edge commit for mesa? haha

14:45 <narmstrong> mrfixit2001: I think you should give us the platform and the kernel you're using aswell !

14:47 <mrfixit2001> Sure! I'm basically using the latest mainline commit directly from torvald's github, with a few customizations from ayufan's repo. Here's the kernel source I'm building: https://github.com/mrfixit2001/mainline-kernel

14:47 <mrfixit2001> the platform being tested is a rockpro64 - rk3399 - mali T860

14:48 <narmstrong> make sure DRM_PANFROST is built and loaded (if is a module), then check the log to see if it has probed !

14:49 <mrfixit2001> Yes, I've ensure panfrost is built into the kernel (CONFIG_DRM_PANFROST=y) and in dmesg I see it being initialized

14:50 <narmstrong> what are you running ? you should try something simple like kmscube first

14:50 <mrfixit2001> [ 3.799426] panfrost ff9a0000.gpu: clock rate = 500000000

14:50 <mrfixit2001> MMU:0x00002830 AS:0xff JS:0x7

14:51 <mrfixit2001> I've tried a few applications so far, all give the same error. They aren't "simple" however, I'm testing a port of recalbox. Prior to adding kmsro to the config it was complaining it couldn't find rockchip DRI, and now it just can't find opengl.

14:52 <mrfixit2001> I expect some of the apps may not work well, but not initializing at all seems like there's an underlying issue with the way I'm building mesa

14:56 <mrfixit2001> Are there some required patches that aren't merged into torvald's master repo yet that I should add? Or am I configuring mesa incorrectly?

14:59 <narmstrong> Not an export for running with OpenGL, but I don't think it required anything specific

15:05 <TheCycoONE> mrfixit2001: it's worked with upstream since 5.2 / mesa 19.2. My mesa build flags don't match yours, not sure if it matters.

15:06 <TheCycoONE> I posted my PKGBUILD here for reference: https://archlinuxarm.org/forum/viewtopic.php?f=8&t=13574

15:06 <TheCycoONE> (it's a bit cargo cult, but it works)

15:18 <mrfixit2001> TheCycoONE thank you for the reply! I would expect since I'm compiling the bleeding-edge commits, that things would still work, but your flags are definitely different than my own. In this build I am not using X or wayland at all, strictly GBM and GLES.

15:19 <mrfixit2001> I'll try recompiling mesa with some of your flags to see what happens.

15:20 <mrfixit2001> I was going off the assumption that this link was still relatively accurate in terms of required flags: https://panfrost.freedesktop.org/building-panfrost-mesa.html

15:37 <robmur01> I only ever explicitly configured "prefix", "gallium_drivers" and "libunwind", and my builds have always worked

15:38 <robmur01> certain GBM things did break on Rockchip about a month ago, but that got fixed again yesterday

15:39 <robmur01> (specifically, things trying to use XRGB formats rather than ARGB)

15:42 <mrfixit2001> robmur01 that's really good to know, thank you! I'm building commit d855e19b87ef6ef674689404f452c7daf31e9486, although I seem to be stuck with even initializing the graphics stack in an application.

15:44 <mrfixit2001> I am rebuilding with these updated flags to see if it makes any difference, although I won't know for a number of hours until I get back home to test ;) https://pastebin.com/pKvPv9Hd

15:46 <robmur01> also, +1 to trying a known-working application like kmscube or glmark2-es2-drm, just as a baseline sanity check

15:49 <mrfixit2001> I have added kmscube to my buildroot package list so that I can test it with this new compile
