Fail to get NVidia driver version since V0.0.10 - working anyway up to V0.0.11 - master fails - NVidia V525.147.05

Open Jasmin68k opened this issue 1 year ago • 3 comments

Hello!

Using the driver on Debian Sid with NVidia drivers V525.147.05, NVidia driver version is not properly detected since V0.0.10 as reported by vainfo.

Hardware decoding in Firefox works anyway, except for latest master branch, where nv-driver.c forces a dummy version of 470.123.45, when no proper NVidia driver version is returned.

Since nv-driver.c sets different parameters depending on detected driver version, it might not work optimally though.

EDIT: If I substitute the dummy driver version in nv-driver.c with 525.147.05, master branch works, too.

Let me know, if you need any further info.

master

Hardware decoding in Firefox works anyway, except for latest master branch

Maybe related to https://github.com/elFarto/nvidia-vaapi-driver/issues/271

From a quick glance at the code:

The nv_get_versions function in nv-driver.c changed somewhere between V0.0.9 and V0.0.10 and, at least on my system, the new version seems to return an empty string (see vainfo output in original post).

nv-driver.c sets different parameters based on driver version in the nv_alloc_object function (f.e. if (driverMajorVersion < 525) {...).

Up to about V0.0.10 these comparisons might not result in an optimal set of values for the 525 driver on my system due to the non-working nv_get_version function, but decoding still works.

In latest master however, the empty string is replaced with dummy version 470.123.45, resulting in the alloc_buffer function handling nvkms_params_size differently .nvkms_params_size = context->driverMajorVersion == 470 ? 0x20 : sizeof(nvkmsParams).

I assume the latter is why latest master does not work anymore on my system, and does work again, if I replace the dummy driver version with 525.147.05.

I don't claim to know exactly, how the code is working, so I might be off here.
