[PATCH umr 0/4] gfx9: read VGPRs of halted waves

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Nicolai,

Patches look good I'll give them a whirl tomorrow when I have some free 
time.  I'll have to dig out your headless piglit instructions since I 
still can't bring X up on my Raven board.

Also I noticed the use of "(options.bitfields)" (etc, in print_waves) 
which is not your bug (since I did it first hehehe) but is a bug ... 
they should all be "asic->options.bitfields" which I'll fix in a 
follow-up patch after.

(provided they apply and combined with the kernel patch doesn't oops on 
me I'll R-b + push them out tomorrow or Monday morning).

Thanks,
Tom
