Note that after resume the bios might or might not have enabled pipe A already. We have a bit of magic to make sure that on resume we set up a decent mode for pipe A, but I fear if I just smash pipe A to always on we'd enable it in a bogus state and hang the hw.

This worked out nicely since the input modes used by both the load detect code and reported in the ->get_modes callbacks all have no flags set, and we also don't fill out any of them in the ->get_config callback. This changed with the additional sanitation done with commit 2960bc9cceecb5d556ce1c07656a6609e2f7e8b0 Author: Imre Deak <imre.deak@intel.com> Date: Tue Jul 30 13:36:32 2013 +0300 drm/i915: make user mode sync polarity setting explicit sinc now the "no flags at all" state wouldn't fit through core code any more. So fix this up again by explicitly clearing the flags in the ->compute_config callback. Aside: We have zero checking in place to make sure that the requested mode is indeed the right input mode we want for the selected TV mode. So we'll happily fall over if userspace tries to pull us. But that's definitely work for a different patch series. So just add a FIXME comment for now.

The first pass finds the length, and the second pass emits the right portion of the string into the accumulation buffer.

| | * drm/msm: workaround for missing irqRob Clark2013-09-111-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | Occasionally we seem to miss an IRQ from the ME (microengine). I'm not entirely sure the root cause, but for now we can unwedge things by retiring from the hangcheck timer. Signed-off-by: Rob Clark <robdclark@gmail.com>
| | * drm/msm: return -EBUSY if bo still activeRob Clark2013-09-113-18/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we CPU_PREP a bo with NOSYNC flag (for example, to implement PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE), an -EBUSY return indicates to userspace that the bo is still busy. Previously it was incorrectly returning 0 in this case. And while we're in there throw in an bit of extra sanity checking in case userspace tries to wait for a bogus fence.

| | | | | | | | | | | | | | | | | | | | | | | | In case of error, the function drm_prime_pages_to_sg() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn>
| | * drm/msm: fix cmdstream size checkRob Clark2013-09-101-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Need to check size+offset against bo size (duh!).. now we have a test case to make sure I've done it right: https://github.com/freedreno/msmtest/blob/master/submittest.c Also, use DRM_ERROR() for error case traces, which makes debugging userspace easier when enabling debug traces is too much.

| | * drm/msm: hangcheck harderRob Clark2013-09-102-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If gpu locks up with the rptr shortly beyond the wrap-around point in the ringbuffer, because the rptr was not reset (but wptr is, by virtue of resetting rb->cur), we could end up in a scenario where we think there is not enough space in the ringbuffer for the next cmds. And since the CP won't reset rptr until after processing an IB, this leaves things in a sort of deadlock. So reset rptr too. And a bit more spiffing up of hangcheck to make things easier to debug.

| | * drm/msm: handle read vs write fencesRob Clark2013-09-104-11/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | The userspace API already had everything needed to handle read vs write synchronization. This patch actually bothers to hook it up properly, so that we don't need to (for example) stall on userspace read access to a buffer that gpu is also still reading.
