2019-12-10drm/ast: Store primary-plane format in struct ast_crtc_stateThomas Zimmermann1-9/+17
Reading the primary plane's framebuffer from the CRTC's atomic_flush() function is fragile as the plane state or framebuffer can be NULL. Instead, we let the plane's atomic_check() store the framebuffer format in the CRTC state. The CRTC always receives the framebuffer format that is currently programmed, or NULL if no mode has been set yet.

2019-12-10drm/ast: Store VBIOS mode info in struct ast_crtc_stateThomas Zimmermann1-28/+30
After looking up VBIOS mode information in CRTC's atomic_check(), we can reuse it in atomic_flush(). No need for a second look-up.

2019-12-10drm/ast: Introduce struct ast_crtc_stateThomas Zimmermann1-2/+27
AST-specific CRTC state can be placed in the new struct ast_crtc_state. The atomic check functions of the CRTC and the primary plane will store the VBIOS mode info and the framebuffer format here. The CRTC will consume these during atomic_flush().

2019-12-10drm/ast: Clean up arguments of register functionsThomas Zimmermann1-62/+43
In preparation of an update of the primary-plane code, this patch changes the arguments of several register-setting functions. No functional changes are made. The function ast_set_dac_reg() has no effect and therefore gets removed entirely.

2019-12-10drm/ast: Enable and disable screen in primary-plane functionsThomas Zimmermann1-9/+19
Enabling and disabling the screen used to be done in the register initialization and the DPMS function. None of these places is related to the screen's output.

2019-07-09drm/ast: Replace struct ast_fbdev with generic framebuffer emulationThomas Zimmermann1-21/+0
This patch replaces ast's framebuffer console with DRM's generic implememtation. All respective code is being removed from the driver. The console is set up with a shadow buffer. The actual buffer object is not permanently pinned in video ram, but just another buffer object that the driver moves in and out of vram as necessary. The driver's function ast_crtc_do_set_base() used to contain special handling for the framebuffer console. With the new generic framebuffer, the driver does not need this code an longer. v2: * use drm_fb_helper_set_suspend_unlocked() in ast_drm_{thaw,freeze}() * dirty function no longer required Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/315835/

2019-05-22drm: Replace drm_gem_vram_push_to_system() with kunmap + unpinThomas Zimmermann1-4/+10
The push-to-system function forces a buffer out of video RAM. This decision should rather be made by the memory manager. By replacing the function with calls to the kunmap and unpin functions, the buffer's memory becomes available, but the buffer remains in VRAM until it's evicted by a pin operation. This patch replaces the remaining instances of drm_gem_vram_push_to_system() in ast and mgag200, and removes the function from DRM.

This may result in validating unlocked TTM BOs. Adding the reserve and unreserve operations to GEM VRAM's pin and unpin functions fixes the bochs and vbox drivers. Additionally the patch changes the mgag200, ast and hibmc drivers to not reserve BOs by themselves.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-0/+1
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.
