drm/vmwgfx: Fix a potential infinite spin waiting for fifo idle

2014-10-05T21:54:08+00:00

commit f01ea0c3d9db536c64d47922716d8b3b8f21d850 upstream. The code waiting for fifo idle was incorrect and could possibly spin forever under certain circumstances.

drm/vmwgfx: Fix incorrect write to read-only register v2:

2014-07-09T18:14:00+00:00

commit 4e578080ed3262ed2c3985868539bc66218d25c0 upstream. Commit "drm/vmwgfx: correct fb_fix_screeninfo.line_length", while fixing a vmwgfx fbdev bug, also writes the pitch to a supposedly read-only register: SVGA_REG_BYTES_PER_LINE, while it should be (and also in fact is) written to SVGA_REG_PITCHLOCK. This patch is Cc'd stable because of the unknown effects writing to this register might have, particularly on older device versions. v2: Updated log message.

drm/vmwgfx: Make sure user-space can't DMA across buffer object boundaries v2

2014-05-31T04:52:14+00:00

commit cbd75e97a525e3819c02dc18bc2d67aa544c9e45 upstream. We already check that the buffer object we're accessing is registered with the file. Now also make sure that we can't DMA across buffer object boundaries. v2: Code commenting update. Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz Signed-off-by: Greg Kroah-Hartman

drm/vmwgfx: correct fb_fix_screeninfo.line_length

2014-05-31T04:52:14+00:00

commit aa6de142c901cd2d90ef08db30ae87da214bedcc upstream. Previously, the vmwgfx_fb driver would allow users to call FBIOSET_VINFO, but it would not adjust the FINFO properly, resulting in distorted screen rendering. The patch corrects that behaviour. See https://bugs.gentoo.org/show_bug.cgi?id=494794 for examples. Signed-off-by: Christopher Friedt Reviewed-by: Thomas Hellstrom Signed-off-by: Greg Kroah-Hartman

drm/vmwgfx: Don't kill clients on VT switch

2013-11-13T03:05:34+00:00

commit c4249855ac5b2a383704d31e040d3831d6a25c6f upstream. DRI clients that tried to grab the TTM lock when the master (X server) was switched away during a VT switch were sent the SIGTERM signal by the kernel. Fix this so that they are only sent that signal when the master has exited.

drm/vmwgfx: add proper framebuffer refcounting

2013-01-20T21:17:11+00:00

Afact vmwgfx already has all the right refcounting implemented on the backing storage, and we only need to ensure that the drm fb doesn't disappear untimely. So holding onto the fb reference from _lookup until vmw_kms_present has completed should be enough. Signed-off-by: Daniel Vetter
