FIX: Nice oops from agpgart - 2.2 kernels and Alpha

2000-10-17 Thread Michal Jaegermann
I complained few days ago that 'agpgart.o' module from 2.2.18pre is causing a kernel oops. The problem turned out to be an apparent assumption that PCI memory <-> memory mapping is an identity and this is not always the case. Here is a patch applicable to all 2.2.18pre kernels with agpgart

Nice oops from agpgart - 2.2 kernels and Alpha

2000-10-13 Thread Michal Jaegermann
On UP1100 Alpha with an AGP slot and "Advanced Micro Devices [AMD] AMD-751 [Irongate] System Controller" an attempt to use 'agpgart' support ends up with an oops. I tried 2.2.17 and 2.2.18pre15 kernels. With CONFIG_AGP=y and CONFIG_AGP_AMD=y resulting kernel gets stuck after oops and does not
