RC6 fails again. > I found my system freeze mostly during starting up X and KDE. Sometimes it > works for some minutes, sometimes it freezes immediatly.

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
