11:44 <mntmn> am i missing some out-of-tree patch to mesa that's important for GC7000L? i unfortunately lost my mesa patchstack due to a failing SSD and rebuilding it now.

12:20 <mntmn> problem goes away when XWAYLAND_NO_GLAMOR env var is set

12:28 <mntmn> ok i found the problem. it's the glClear() in glamor_pixmap_clear_fbo() causing etnaviv to go into a corrupted state, still

12:30 <mntmn> ah shit i already found this 6 months ago and forgot https://gitlab.freedesktop.org/xorg/xserver/-/issues/941

12:45 <mntmn> workaround https://gitlab.freedesktop.org/xorg/xserver/-/issues/941#note_517054

15:18 <cphealy> With these Vivante GPUs and their associated HW counters, are there any that could be accessed independent of using Mesa? On the NXP i.MX8M, I have access to read the DRAM interface counters using the "perf" tool. I'm wondering if support could be added to read the GPU host interface counters through the "perf" tool while still retaining the existing counter access through Mesa.

15:46 <austriancoder> cphealy: sure.. I have some wip stuff: https://github.com/austriancoder/linux/tree/perfetto

15:47 <cphealy> oh cool!

15:49 <cphealy> My long term vision is to be able to have a single tool that on these i.MX based platforms we can show system wide utilization in real-time. CPU load, DDR bus load, video encoder/decoder load, and GPU load. For GPU, it would be good to have an overall busy % but also read/write and busy time for the GPU sub-components.

15:55 <austriancoder> cphealy: and this tool is https://perfetto.dev/

15:56 <cphealy> austriancoder: do you have example output from this?

16:01 <austriancoder> You can load some in the web UI.. I am currently not at home

16:05 <daniels> cphealy: yep that's what we've been working on! :)

16:08 <cphealy> daniels: Do you mean your working on perfetto.dev implementation that fits with what austriancoder is doing?

16:18 <daniels> cphealy: right, including Weston timeline which we could previously only get through wesgr

16:19 <daniels> cphealy: I can send you a draft blog post we have about it tomorrow or Monday, or I'm pretty sure it's in your email somewhere if you search for 'perfetto'

16:20 <cphealy> With the mesa/kernel side work being done, would something like this be possible: https://awesomedetect.com/wp-content/uploads/2018/07/rsz_1screenshot_from_2018-07-30_14-40-36-min.jpg

16:20 <cphealy> Being able to log into a unit and run a tool to see instantaneous load on the different cores is one of the things I'm looking ofr.

16:27 <cphealy> Something like fdperf would also be nice: http://bloggingthemonkey.blogspot.com/2016/05/freedreno-not-so-periodic-update.html
