drm/msm: rd dumping support for sparse

2025-07-05T00:48:37Z

As with devcoredump, we need to iterate the VMAs to figure out what to dump. Signed-off-by: Rob Clark Signed-off-by: Rob Clark Tested-by: Antonino Maniscalco Reviewed-by: Antonino Maniscalco Patchwork: https://patchwork.freedesktop.org/patch/661510/

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43Z

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

drm/msm: don't create GPU-related debugfs files with no GPU present

2023-11-21T02:31:42Z

If there is no GPU present, skip creation of the GPU-related debugfs files, making the MSM's debugfs more usable. Signed-off-by: Dmitry Baryshkov Patchwork: https://patchwork.freedesktop.org/patch/561742/ Signed-off-by: Rob Clark

drm/msm: Use drm_gem_object in submit bos table

2023-08-10T17:44:02Z

Basically everywhere wants the base ptr type. So store that instead of msm_gem_object. Signed-off-by: Rob Clark Patchwork: https://patchwork.freedesktop.org/patch/551021/

drm/msm: Move cmdstream dumping out of sched kthread

2023-06-10T13:46:12Z

This is something that can block for arbitrary amounts of time as userspace consumes from the FIFO. So we don't really want this to be in the fence signaling path. Signed-off-by: Rob Clark Patchwork: https://patchwork.freedesktop.org/patch/532617/

drm/msm/rd: Fix FIFO-full deadlock

2022-08-15T17:19:53Z

If the previous thing cat'ing $debugfs/rd left the FIFO full, then subsequent open could deadlock in rd_write() (because open is blocked, not giving a chance for read() to consume any data in the FIFO). Also it is generally a good idea to clear out old data from the FIFO.

drm/msm: Add support for pointer params

2022-04-21T22:01:08Z

The 64b value field is already suffient to hold a pointer instead of immediate, but we also need a length field. Signed-off-by: Rob Clark Link: https://lore.kernel.org/r/20220317165144.222101-2-robdclark@gmail.com Signed-off-by: Rob Clark

drm/msm/rd: Add chip-id

2022-02-18T15:32:52Z

For newer devices which deprecate gpu-id and do matching based on chip-id, we need this information in cmdstream dumps so that the decoding tools know how to decode them.
