AMD "Hawaii" Open-Source GPU Acceleration Still Not Working Right
I just tested nouveau again solely because of this comment, same GPU, without blobbed FW this time
My performance in portal2 is now comparable to nvidia's driver (slightly worse), due to default high clocks
Maybe it's time for modifying VBIOS before attempting honest benchmark? At least for the NV50
I would definitely switch to open drivers but there are certain problems. First, this is a laptop. Second, the GPU I have (GT 9600M) is really very-very hot even while using nvidia driver. So I'm not sure how safe it would be to use nouveau since it has obvious problems with power management.
[Tue Jul 22 22:17:52 2014] nouveau [ PTHERM][0000:01:00.0] temperature (90 C) hit the 'fanboost' threshold
[Tue Jul 22 22:17:55 2014] nouveau [ PTHERM][0000:01:00.0] temperature (86 C) went below the 'fanboost' threshold
[Tue Jul 22 17:09:01 2014] nouveau [ PTHERM][0000:01:00.0] temperature (96 C) hit the 'downclock' threshold
[Tue Jul 22 17:16:16 2014] nouveau [ PTHERM][0000:01:00.0] temperature (92 C) went below the 'downclock' threshold
PTHERM has other means to downclock GPU, and AFAIK it has the same settings as nvidia blob
And nvidia blob manages to get temperatures over 110°C (no dust, fresh paste, compal JHL90) . Idle temperature is just 15°C higher on nouveau, power consumption is probably much bigger issue
Also i have noticed that nvidia somehow has memory leaks and uses way more cpu/ram… I just hope to reach 14 days uptime again
(About my portal2 testing: i forgot to test any valve maps … and fps drops noticeably there to almost unplayable level)
Note that the 7790 is supposed to be GCN 1.0 while 260X is supposed to be GCN 1.1 which is quite contradictory with the above information... Maybe the 7790 was like a GCN 1.1 prototype... The 7790 was released 14 months after the first 7000 series cards and only 7 months before the first 200 series cards.
7790 was always GCN 1.1, and yes, it was the prototype they used to test yields of the architecture.
So, Alex, what was the problem? The typos uncovered by Jerome and bugs in firmware only?
Also as a side question, is there any news on hyperz issues? I mean is it known what causes this weird corruption in shadows? From a user prospective this is one of the last annoying bugs in radeonsi for me.
