drm/: Don't set FBINFO_(FLAG_)DEFAULT

2019-01-29T09:56:42Z

Both macros evaluate to 0. At the same time flag is already set to zero since the struct is kzalloc'd in framebuffer_alloc(). As called by drm_fb_helper_alloc_fbi() in the DRM drivers. v2: Rebase and improve commit message per Emil's suggestion.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42Z

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

drm/tegra: Convert drm_atomic_helper_suspend/resume()

2018-09-18T14:53:54Z

convert drm_atomic_helper_suspend/resume() to use drm_mode_config_helper_suspend/resume(). With this conversion, tegra_drm_fb_suspend() and tegra_drm_fb_resume() will not be used anymore. Both of these functions can be removed. Also, in tegra_drm struct's member state will not be used anymore. So this can be removed forever. Fixed one sparse warning.

drm/tegra: Use drm_gem_fb_destroy

2018-05-17T15:44:48Z

Now that our destroy function is the same as the helper, use that directly. Signed-off-by: Daniel Stone Cc: Thierry Reding Cc: linux-tegra@vger.kernel.org Signed-off-by: Thierry Reding

drm/tegra: Move fbdev unmap special case

2018-05-17T15:44:48Z

User framebuffers are created with either bo->pages or bo->vaddr set, depending on whether or not an IOMMU is present. On the other hand, the framebuffer created for fbdev emulation has a vaddr mapping made if bo->pages is set after creation. This is set up in fbdev probe. Remove the special case unmapping from the general-purpose framebuffer destroy, and move it to fbdev teardown.

drm/tegra: tegra_fb -> drm_framebuffer

2018-05-17T15:44:48Z

Since tegra_fb is now the same as drm_framebuffer, we can just replace the type completely. Signed-off-by: Daniel Stone Cc: Thierry Reding Cc: linux-tegra@vger.kernel.org Signed-off-by: Thierry Reding

drm/tegra: Move GEM BOs to drm_framebuffer

2018-05-17T15:44:48Z

Since drm_framebuffer can now store GEM objects directly, place them there rather than in our own subclass. As this makes the framebuffer create_handle function the same as the GEM framebuffer helper, we can reuse that.

drm/tegra: Remove duplicate framebuffer num_planes

drm_framebuffer already stores num_planes for us. Signed-off-by: Daniel Stone Cc: Thierry Reding Cc: linux-tegra@vger.kernel.org Signed-off-by: Thierry Reding

drm/tegra: fb: Properly support linear modifier

2018-03-15T18:06:19Z

Instead of relying on the tiling attached to a buffer object, make sure to set the proper tiling for linear buffers. Signed-off-by: Thierry Reding

drm/tegra: fb: Implement ->fb_mmap() callback

2018-03-08T13:38:42Z

This fixes hangs with legacy applications that use the mmap() syscall on the fbdev device to map framebuffer memory. The fbdev implementation for mmap() creates a mapping that conflicts with DRM usage and causes a hang when the memory is accessed through the mapping.
