drm/msm: Add msm_gem_get_and_pin_iova()

2018-12-11T18:05:32Z

Add a new function to get and pin the iova memory in one step (basically renaming the old msm_gem_get_iova function) and switch msm_gem_get_iova() to only allocate an iova but not map it in the IOMMU. This is only currently used by msm_ioctl_gem_info() since all other users of of the iova expect that the memory be immediately available. Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark

drm: msm: Use DRM_DEV_* instead of dev_*

2018-12-11T18:05:22Z

Use DRM_DEV_INFO/ERROR/WARN instead of dev_info/err/debug to generate drm-formatted specific log messages so that it will be easy to differentiate in case of multiple instances of driver. Signed-off-by: Mamta Shukla Signed-off-by: Rob Clark

drm/msm: don't deref error pointer in the msm_fbdev_create error path

2018-04-19T14:09:41Z

Currently the error pointer returned by msm_alloc_stolen_fb gets passed to drm_framebuffer_remove. The latter handles only NULL pointers, thus a nasty crash will occur. Drop the unnecessary fail label and the associated checks - both err and fb will be set at this stage.

Updates for 4.14.. I have some further patches from Jordan to add multiple priority levels and pre-emption, but those will probably be for 4.15 to give me time for the mesa parts. * tag 'drm-msm-next-2017-08-22' of git://people.freedesktop.org/~robclark/linux: drm/msm/mdp5: mark runtime_pm functions as __maybe_unused drm/msm: remove unused variable drm/msm/mdp5: make helper function static drm/msm: make msm_framebuffer_init() static drm/msm: add helper to allocate stolen fb drm/msm: don't track fbdev's gem object separately drm/msm: add modeset module param drm/msm/mdp5: add tracking for clk enable-count drm/msm: remove unused define drm/msm: Add a helper function for in-kernel buffer allocations drm/msm: Attach the GPU MMU when it is created drm/msm: Add A5XX hardware fault detection drm/msm: Remove uneeded platform dev members drm/msm/mdp5: Set up runtime PM for MDSS drm/msm/mdp5: Write to SMP registers even if allocations don't change drm/msm/mdp5: Don't use mode_set helper funcs for encoders and CRTCs drm/msm/dsi: Implement RPM suspend/resume callbacks drm/msm/dsi: Set up runtime PM for DSI drm/msm/hdmi: Set up runtime PM for HDMI drm/msm/mdp5: Use runtime PM get/put API instead of toggling clocks

drm/msm: add helper to allocate stolen fb

2017-08-22T17:20:39Z

We'll later want to re-use this for state-readback when bootloader enables display, so that we can create an fb for the initial plane->state->fb. Signed-off-by: Rob Clark

drm/msm: don't track fbdev's gem object separately

2017-08-22T17:20:38Z

The drm_framebuffer is refcnt'd these days and will unref the underlying bo as needed. So we can simplify a little. Signed-off-by: Rob Clark

drm/: Drop fbdev info flags

2017-07-26T11:22:40Z

- FBINFO_CAN_FORCE_OUTPUT has been a lie ever since we nerfed&removed the entire panic handling code in our fbdev emulation. We might restore kms panic output, but not through the bazillion of legacy code layers called fbdev/fbcon, there's just no way to make that work safely. - With the module check change FBINFO_DEFAULT is always 0, so can be removed too. That removes another change to cargo-cult stuff in kms drivers, yay!

drm/msm: Separate locking of buffer resources from struct_mutex

2017-06-17T12:03:07Z

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.
