git://people.freedesktop.org/~robclark/linux into drm-fixes A few fixes for v5.0.. the opp-level fix and removal of hard-coded irq name is partially to make things smoother in v5.1 merge window to avoid dependency on drm vs dt trees, but are otherwise sane changes.

2018-12-11drm/msm/gpu: add submit flag to hint which buffers should be dumpedRob Clark1-3/+10
To lower CPU overhead, future userspace will be switching to pinning iova and avoiding the use of relocs, and only include cmds table entries for IB1 level cmdstream (but not IB2 or state-groups). This leaves the kernel unsure what to dump for rd/hangrd cmdstream dumping. So add a MSM_SUBMIT_BO_DUMP flag so userspace can indicate buffers that contain cmdstream (or are otherwise important to dump). Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-11-30drm/msm: fix handling of cmdstream offsetRob Clark1-1/+4
Userspace hasn't used submit cmds with submit_offset != 0 for a while, but this starts cropping up again with cmdstream sub-buffer-allocation in libdrm_freedreno. Doesn't do much good to increment the buf ptr before assigning it. Fixes: 78b8e5b847b4 drm/msm: dump a rd GPUADDR header for all buffers in the command Reviewed-by: Kristian H.

2018-10-04drm/msm/rd: fix crash with long process cmdlinesRob Clark1-3/+3
The [v]snprintf() functions return the size that *would have* been written into the buffer, rather than the size *actually* written. Which results in us trying to memcpy() past the end of the stack. What we really want is [v]scnprintf(). Signed-off-by: Rob Clark <robdclark@gmail.com>

Linux 4.14-rc7 Requested by Ben Skeggs for nouveau to avoid major conflicts, and things were getting a bit conflicty already, esp around amdgpu reverts.
2017-10-28drm/msm/rd: allow adding addition msg to top of dumpRob Clark1-2/+13

2017-10-28drm/msm: split rd debugfs fileRob Clark1-26/+75
Split into two instances, the existing $debugfs/rd which continues to dump all submits, and $debugfs/hangrd which will be used to dump just submits that cause gpu hangs (and eventually faults, but that will require some iommu framework enhancements). Signed-off-by: Rob Clark <robdclark@gmail.com>
2017-10-28drm/msm: add special _get_vaddr_active() for cmdstream dumpsRob Clark1-1/+1
Prep work for adding a debugfs file that dumps just submits which trigger hangs/faults. In this case the bo may already be in the MADV_DONTNEED state, but will be still on the active list (since the submit hasn't completed yet). So the normal check that the bo is in the WILLNEED state does not apply. (But of course the bo should definitely not be in the PURGED state!) Signed-off-by: Rob Clark <robdclark@gmail.com>
2017-10-28drm/msm: dump a rd GPUADDR header for all buffers in the commandJordan Crouse1-15/+15
Currently the rd dump avoids any buffers marked as WRITE under the assumption that the contents are not interesting. While it is true that the contents are uninteresting we should still print the iova and size for all buffers so that any listening replay tools can correctly construct the submission. Print the header for all buffers but only dump the contents for buffers marked as READ. Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2017-06-17drm/msm: Separate locking of buffer resources from struct_mutexSushmita Susheelendra1-2/+2
Buffer object specific resources like pages, domains, sg list need not be protected with struct_mutex. They can be protected with a buffer object level lock. This simplifies locking and makes it easier to avoid potential recursive locking scenarios for SVM involving mmap_sem and struct_mutex. This also removes unnecessary serialization when creating buffer objects, and also between buffer object creation and GPU command submission.

2017-03-01drm/msm: Remove drm_debugfs_remove_files() callsNoralf Trønnes1-28/+3
drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so it's not necessary to call drm_debugfs_remove_files(). Additionally it uses debugfs_remove_recursive() to clean up the debugfs files, so no need to do that.

2016-07-16drm/msm/rd: add module param to dump all bo'sRob Clark1-7/+31
By default, if using $debugfs/.../rd to log cmdstream, only the cmdstream buffers themselves are logged. But in some cases we want to capture other buffers in the submit (to see VBO's or shaders). So add a mod-param knob to control this. Signed-off-by: Rob Clark <robdclark@gmail.com>

2016-07-16drm/msm: change gem->vmap() to get/putRob Clark1-1/+3

2016-06-04drm/msm: deal with exhausted vmap space betterRob Clark1-0/+3

2014-06-02drm/msm: add rd logging debugfsRob Clark1-0/+337
To ease debugging, add debugfs file which can be cat/tail'd to log submits, along with fence #. If GPU hangs, you can look at 'gpu' debugfs file to find last completed fence and current register state, and compare with logged rd file to narrow down the DRAW_INDX which triggered the GPU hang.
