drm/msm: use drm_gem_dumb_destroy helper

drm/msm: deal with mach/iommu.h removal

2013-09-28T14:07:06Z

We still need an API exported by msm iommu driver (but not visible in any public header anymore). For now, just declare the prototype ourselves, but when msm iommu driver provides a better option, use that instead. Signed-off-by: Rob Clark

drm/msm: Remove iommu include from mdp4_kms.c

2013-09-28T13:17:31Z

The include file has been removed and the file does not need it anyway, so remove it. Fixes a compile error. Signed-off-by: Joerg Roedel Signed-off-by: Rob Clark

drm/msm: Odd PTR_ERR usage

2013-09-28T12:53:26Z

The variable priv->kms is not initialized yet. Found by "scripts/coccinelle/tests/odd_ptr_err.cocci". PTR_ERR should access the value just tested by IS_ERR. Signed-off-by: Thomas Meyer

drm/msm: drop unnecessary set_need_resched()

2013-09-16T11:59:49Z

This was inherited from i915/udl, and not actually needed. Signed-off-by: Rob Clark

drm/msm: fix potential NULL pointer dereference

2013-09-12T14:32:12Z

The dereference to 'pdata' should be moved below the NULL test. Signed-off-by: Wei Yongjun

drm/msm: workaround for missing irq

2013-09-11T21:37:48Z

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

drm/msm: return -EBUSY if bo still active

2013-09-11T21:36:28Z

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. Signed-off-by: Rob Clark

drm/msm: fix return value check in ERR_PTR()

2013-09-11T21:31:33Z

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

drm/msm: fix cmdstream size check

2013-09-10T17:57:42Z

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.
