drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

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/stm: prepare for drmP.h removal from drm_modeset_helper.h

2019-01-24T12:06:35+00:00

The use of drmP.h is discouraged and removal of it from drm_modeset_helper.h caused drm/stm to fail to build. This patch introduce the necessary fixes to prepare for the drmP.h removal from drm_modeset_helper.h.

drm/stm: Use drm_fbdev_generic_setup()

2018-10-25T15:00:28+00:00

The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing. drm_fbdev_generic_setup() handles mode_config.num_connector being zero. In that case it retries fbdev setup on the next .output_poll_changed.

drm: stm: implement get_scanout_position function

2018-09-27T13:04:26+00:00

Hardware allow to read the position in scanout buffer so we can use this information to make wait of vblank more accurate. Active area bounds (start, end, total height) have already been computed and written in ltdc registers, read them and get the current line position to compute vpos value.

drm/stm: Replace drm_dev_unref with drm_dev_put

2018-07-13T08:11:02+00:00

This patch unifies the naming of DRM functions for reference counting of struct drm_device. The resulting code is more aligned with the rest of the Linux kernel interfaces.

drm/stm: Use drm_fb_cma_fbdev_init/fini()

2017-12-08T13:47:41+00:00

Use drm_fb_cma_fbdev_init() and drm_fb_cma_fbdev_fini() which relies on the fact that drm_device holds a pointer to the drm_fb_helper structure. This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly. Remove duplicate ldev assignment.
