drm/irq: Don't check for DRIVER_HAVE_IRQ in drm_irq_(un)install

2019-01-29T14:45:06Z

If a non-legacy driver calls these it's valid to assume there is interrupt support. The flag is really only needed for legacy drivers, which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL legacy IOCTL. Also remove all the flag usage from non-legacy drivers. v2: Review from Emil: - improve commit message - I forgot hibmc, fix that Cc: linux-arm-kernel@lists.infradead.org Cc: intel-gfx@lists.freedesktop.org Cc: linux-amlogic@lists.infradead.org Cc: linux-arm-msm@vger.kernel.org Cc: freedreno@lists.freedesktop.org Cc: virtualization@lists.linux-foundation.org Cc: spice-devel@lists.freedesktop.org Cc: amd-gfx@lists.freedesktop.org Cc: linux-renesas-soc@vger.kernel.org Reviewed-by: Emil Velikov Reviewed-by: Sam Ravnborg Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190129104248.26607-1-daniel.vetter@ffwll.ch

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/hisilicon/kirin: prepare for drmP.h removal from drm_modeset_helper.h

2019-01-24T12:06:43Z

The use of drmP.h is discouraged and removal of it from drm_modeset_helper.h caused kirin to fail to build. This patch introduce the necessary fixes to prepare for the drmP.h removal from drm_modeset_helper.h. List of include files sorted alphabetically. Build tested on arm x86 allmodconfig using the following hack to the Kconfig file: | - depends on DRM && OF && ARM64 | + depends on DRM && OF && (ARM64 || (X86_64 && COMPILE_TEST)) Build failed on 32bit ARM - so the X86_64 hack was required. The COMPILE_TEST hack is not submitted as the preferred fix is something where we have coverage on 32bit ARM too. v2: - Sort list of include files Signed-off-by: Sam Ravnborg Cc: Xinliang Liu Cc: Rongrong Zou Cc: Xinwei Kong Cc: Chen Feng Cc: David Airlie Cc: Daniel Vetter Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190119084014.5355-3-sam@ravnborg.org

drm/hisilicon/kirin: Use drm_fbdev_generic_setup()

2019-01-14T11:33:36Z

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. struct kirin_drm_private can be removed now that driver doesn't have to store the fbdev pointer.

drm/ttm: use a static ttm_mem_global instance

drm/ttm: Rename ttm_bo_global_{init,release}() to ttm_bo_global_ref_{,}()

2018-11-05T19:20:52Z

The functions ttm_bo_global_init() and ttm_bo_global_release() do not receive an argument of type struct ttm_bo_global. Both take a struct drm_global_reference that contains points to a struct ttm_bo_global_ref. Renaming them reflects this.

drm/hisilicon: Replace ttm_bo_unref with ttm_bo_put

2018-09-26T03:42:12Z

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch.
