01:30 <Marex> flto: when was the last time you tried a2xx against mainline Linux/Mesa ?

01:32 <flto> Marex: for mesa ~1 month ago, kernel I tried 5.7

01:33 <Marex> flto: on mx51 or mx53 ?

01:33 <Marex> flto: is there anything special I need or does it just work , e.g. kmscube -D /dev/dri/card1 should just ... work ?

01:35 <flto> Marex: imx51.. GPU should just work - I had a problem with the display on my device in 5.7 but I think something like imx53-qsb should be fine

01:36 <Marex> flto: all right, thanks

12:33 <daniels> cphealy: yeah, that would certainly be very doable

12:36 <Marex> flto: so on anything newer than Linux 5.0 (basically since your a2xx patches landed), I get [drm:a2xx_hw_init] *ERROR* A200: timeout waiting for GPU to idle!

12:37 <Marex> flto: rings any bells ?

12:53 <Marex> ok, found it, it seems to be a kernel bug in init_me()

13:03 <Marex> flto: so the CP_SET_PROTECTED_MODE is apparently invalid instruction

13:06 <flto> Marex: oh right, that's a firmware version problem, you need more recent firmware (or disable the protected mode I guess)

13:08 <Marex> flto: where do I obtain that recent firmware from ?

13:11 <flto> this should be it https://gist.github.com/flto/94652ea0dcf1761e7dd8fc1626fe313f/raw/cd632ee409c6a66384f67a26dd0abb557bfaa661/yamato_pfp.fw https://gist.github.com/flto/94652ea0dcf1761e7dd8fc1626fe313f/raw/cd632ee409c6a66384f67a26dd0abb557bfaa661/yamato_pm4.fw

13:11 <Marex> flto: is there some "more official" source ?

13:12 <Marex> 28272f52d06aa44f7e2d624de7187755c8215a054d3c8e8e6d0656cd9ab13540 yamato_pfp.fw

13:12 <Marex> 3237f5347bec0a00db475933f39724099aa8a96bc571c49a6df0b132c002cd36 yamato_pm4.fw

13:12 <Marex> do these sha256sum look OK ?

13:13 <flto> nope.. I had an my TODO list make the kernel check the FW version and disable protected mode (with a warning, because it shouldn't be disabled..) so you can use the FW extracted from amdgpu driver headers

13:17 <Marex> flto: so I might as well add it on mine too, if that's OK with you?

13:21 <Marex> flto: btw do you have a new firmware for MX51 too ?

13:27 <flto> its the same for both

13:29 <Marex> oh, all right

13:29 <Marex> flto: does the hash match ?

13:30 <flto> yes

13:32 <Marex> flto: thanks
