Hi! [ I suspect dri-devel is going to bounce my mails, so I'm CC'ing linux-kernel ]
DRI stopped working on my setup in Linux 2.6.9-rc1-bk12. I've narrowed the problem down to this changeset (Drop __HAVE_CTX_BITMAP, __HAVE_SG, __HAVE_PCI_DMA): http://linux.bkbits.net:8080/linux-2.5/[EMAIL PROTECTED] Backing this patch out makes DRI in -bk12 work again. I've verified this on two machines with PCI Radeon 7000 cards, so there's PCIGART stuff involved; unfortunately I don't have any AGP Radeons to test with. (I originally suspected the __REALLY_HAVE_AGP change, but that's fine, along with the DRIVER_FILE_FIELDS removal). For what it matters, I'm primarily testing on a ppc Macintosh, but I've verified this on a PC too. Wow, there was no kidding about DRM being difficult to read. :-) I hope this is helpful, but I don't urgently need DRI working. I'd be glad to give any help tracking the problem down. On kernels with non-working DRM, I get this message from the kernel: [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held [drm:radeon_unlock] *ERROR* Process 2150 using kernel context 0 While X says: [24] 0 0 0x000003c0 - 0x000003df (0x20) IS[B](OprU) drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: Open failed drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: open result is -1, (Unknown error 999) drmOpenDevice: Open failed drmOpenDevice: minor is 0 drmOpenDevice: node name is /dev/dri/card0 drmOpenDevice: open result is 7, (OK) drmGetBusid returned '' (II) RADEON(0): [drm] loaded kernel module for "radeon" driver (II) RADEON(0): [drm] created "radeon" driver at busid "PCI:0:18:0" (II) RADEON(0): [drm] added 8192 byte SAREA at 0xcd971000 (II) RADEON(0): [drm] mapped SAREA 0xcd971000 to 0xb5d89000 (II) RADEON(0): [drm] framebuffer handle = 0xd8000000 (II) RADEON(0): [drm] added 1 reserved context for kernel (EE) RADEON(0): [pci] Out of memory (-1007) <------- *** LOOK HERE *** (II) RADEON(0): [drm] removed 1 reserved context for kernel (II) RADEON(0): [drm] unmapping 8192 bytes of SAREA 0xcd971000 at 0xb5d89000 (II) RADEON(0): Memory manager initialized to (0,0) (1280,6553) (II) RADEON(0): Reserved area from (0,1024) to (1280,1026) (II) RADEON(0): Largest offscreen area available: 1280 x 5527 (II) RADEON(0): Using XFree86 Acceleration Architecture (XAA) <snip> (II) RADEON(0): Direct rendering disabled Thanks! -- Joseph Fannin [EMAIL PROTECTED] "Bull in pure form is rare; there is usually some contamination by data." -- William Graves Perry Jr.
