I'm running NetBSD/i386 5.99.24 on an MSI board with an ATI Radeon 2400 XT plugged in. To have 2d acceleration and XVideo, I load radeondrm.kmod at boottime. It usually works, but after restarting X sufficiently often, it suddenly stops; that is, either display is corrupted, or X does not find DRI support anymore. There are a
i see this on two of my systems. one of the problems with restarting is that memory has become fragmented and drm is not able to allocate what it wants, and becomes disabled. few pecularities: >From dmesg (which is also attached): agp0 at pchb0: can't find internal VGA device config space ... ppb0: unsupported PCI Express version this is ignoreable... ... vga1: WARNING: ignoring 64-bit BAR @ 0x10 vga1: WARNING: ignoring 64-bit BAR @ 0x18 and, after each restart of X: info: [drm] Setting GART location based on new memory map info: [drm] Loading RV610 Microcode info: [drm] Resetting GPU info: [drm] writeback test failed ffffffff deadbeef i always get this writeback test fail as well. i bet you do too, it doesn't seem to be a problem... but i have not investigated what it means. Usually, after a while I get a message that something failed; I think it has to do with the memory map, but unfortunately I can't reproduce it at the moment. yup, the first problem is memory related. there are more, but as yet i don't know what is up. Trying to reproduce the problem, I tried to fill up RAM and make the system use swap. Indeed, radeondrm then got detached: radeondrm0: detached yuck. this seems unfortunate. i don't use the drm modules, mine are built in. i recommend using them that way until someone looks at making the radeondrm module less problematic. i'm looking at this problem, but for me the simplest workaround is to not restart X. if i do, the good old 'huge dd block size' trick works to force memory to become available most of the time, but as i meantioned above, there is at least one other problem that stops it working sometimes, but i do not yet have an idea what is going on. can i send you patches to test, ifwhen i have them? thanks. .mrg.
