radeon: Fix disabling PCI bus mastering on big endian hosts.

2012-01-26T00:13:12Z

commit 3df96909b75835d487a9178761622b0cbd7310d4 upstream. It would previously write basically random bits to PCI configuration space... Not very surprising that the GPU tended to stop responding completely. The resulting MCE even froze the whole machine sometimes. Now resetting the GPU after a lockup has at least a fighting chance of succeeding. Signed-off-by: Michel Dänzer Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: disable writeback on pre-R300 asics

2012-01-26T00:13:12Z

commit 28eebb703e28bc455ba704adb1026f76649b768c upstream. We often end up missing fences on older asics with writeback enabled which leads to delays in the userspace accel code, so just disable it by default on those asics.

drm/radeon/kms: workaround invalid AVI infoframe checksum issue

2012-01-26T00:13:11Z

commit 92db7f6c860b8190571a9dc1fcbc16d003422fe8 upstream. This change was verified to fix both issues with no video I've investigated. I've also checked checksum calculation with fglrx on: RV620, HD54xx, HD5450, HD6310, HD6320. Signed-off-by: Rafał Miłecki Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

vmwgfx: fix incorrect VRAM size check in vmw_kms_fb_create()

2011-12-22T12:31:02Z

Commit e133e737 didn't correctly fix the integer overflow issue. - unsigned int required_size; + u64 required_size; ... required_size = mode_cmd->pitch * mode_cmd->height; - if (unlikely(required_size > dev_priv->vram_size)) { + if (unlikely(required_size > (u64) dev_priv->vram_size)) { Note that both pitch and height are u32. Their product is still u32 and would overflow before being assigned to required_size. A correct way is to convert pitch and height to u64 before the multiplication. required_size = (u64)mode_cmd->pitch * (u64)mode_cmd->height; This patch calls the existing vmw_kms_validate_mode_vram() for validation.

drm/radeon/kms: bail on BTC parts if MC ucode is missing

2011-12-22T12:28:01Z

We already do this for cayman, need to also do it for BTC parts. The default memory and voltage setup is not adequate for advanced operation. Continuing will result in an unusable display. Signed-off-by: Alex Deucher Cc: stable@kernel.org Cc: Jean Delvare Signed-off-by: Dave Airlie
