2020-10-09drm/atomic: Pass the full state to CRTC atomic enable/disableMaxime Ripard
If the CRTC driver ever needs to access the full DRM state, it can't do so at atomic_enable / atomic_disable time since drm_atomic_helper_swap_state will have cleared the pointer from the struct drm_crtc_state to the struct drm_atomic_state before calling those hooks. In order to allow that, let's pass the full DRM state to atomic_enable and atomic_disable. The conversion was done using the coccinelle script below, built tested on all the drivers and actually tested on vc4. virtual report @@ struct drm_crtc_helper_funcs *FUNCS; identifier dev, state; identifier crtc, crtc_state; @@ disable_outputs(struct drm_device *dev, struct drm_atomic_state *state) { <... - FUNCS->atomic_disable(crtc, crtc_state); + FUNCS->atomic_disable(crtc, state); ...> } @@ struct drm_crtc_helper_funcs *FUNCS; identifier dev, state; identifier crtc, crtc_state; @@ drm_atomic_helper_commit_modeset_enables(struct drm_device *dev, struct drm_atomic_state *state) { <... - FUNCS->atomic_enable(crtc, crtc_state); + FUNCS->atomic_enable(crtc, state); ...> } @@ identifier crtc, old_state; @@ struct drm_crtc_helper_funcs { ... - void (*atomic_enable)(struct drm_crtc *crtc, struct drm_crtc_state *old_state); + void (*atomic_enable)(struct drm_crtc *crtc, struct drm_atomic_state *state); ... - void (*atomic_disable)(struct drm_crtc *crtc, struct drm_crtc_state *old_state); + void (*atomic_disable)(struct drm_crtc *crtc, struct drm_atomic_state *state); ... } @ crtc_atomic_func @ identifier helpers; identifier func; @@ ( static struct drm_crtc_helper_funcs helpers = { ..., .atomic_enable = func, ..., }; | static struct drm_crtc_helper_funcs helpers = { ..., .atomic_disable = func, ..., }; ) @ ignores_old_state @ identifier crtc_atomic_func.func; identifier crtc, old_state; @@ void func(struct drm_crtc *crtc, struct drm_crtc_state *old_state) { ... when != old_state } @ adds_old_state depends on crtc_atomic_func && !ignores_old_state @ identifier crtc_atomic_func.func; identifier crtc, old_state; @@ void func(struct drm_crtc *crtc, struct drm_crtc_state *old_state) { + struct drm_crtc_state *old_state = drm_atomic_get_old_crtc_state(state, crtc); ... } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; expression E; type T; @@ void func(...) { ... - T state = E; + T crtc_state = E; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; type T; @@ void func(...) { ... - T state; + T crtc_state; <+... - state + crtc_state ...+> } @ depends on crtc_atomic_func @ identifier crtc_atomic_func.func; identifier old_state; identifier crtc; @@ void func(struct drm_crtc *crtc, - struct drm_crtc_state *old_state + struct drm_atomic_state *state ) { ... } @ include depends on adds_old_state @ @@ #include <drm/drm_atomic.h> @ no_include depends on !include && adds_old_state @ @@ + #include <drm/drm_atomic.h> #include <drm/...> Signed-off-by: Maxime Ripard <maxime@cerno.tech> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/845aa10ef171fc0ea060495efef142a0c13f7870.1602161031.git-series.maxime@cerno.tech

2018-07-03drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom
Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

Note that I didn't put parens around the cpp*8 in the below cocci script, on account of not wanting spurious parens all over the place. Instead I did the unsafe way, and tried to look over the entire diff to spot if any dangerous expressions were produced. I didn't see any. There are some cases where previously the code did X*bpp/8, so the division happened after the multiplication.

2016-08-16drm/kms: Nuke dirty_info propertyDaniel Vetter
It was added way back together with the dirty_fb ioctl, but neither generic xfree86-modesetting nor the vmware driver use it. Everyone is supposed to just unconditionally call the dirtyfb when they do frontbuffer rendering. And since unused uabi is bad uabi (there's reasons we require open source userspace for everything) let's nuke this.

2015-12-08drm/vmwgfx: Implement the cursor_set2 callback v2Thomas Hellstrom
Fixes native drm clients like Fedora 23 Wayland which now appears to be able to use cursor hotspots without strange cursor offsets. Also fixes a couple of ignored error paths. Since the core drm cursor hotspot is incompatible with the legacy vmwgfx hotspot (the core drm hotspot is reset when the drm_mode_cursor ioctl is used), we need to keep track of both and add them when the device hotspot is set. We assume that either is always zero. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Sinclair Yeh <syeh@vmware.com>

2015-08-05drm/vmwgfx: Implement fbdev on kms v2Thomas Hellstrom
With screen targets the old legacy display system fbdev doesn't work satisfactory anymore. At best the resolution is severely restricted. Therefore implement fbdev on top of the kms system. With this change, fbdev will be using whatever KMS backend is chosen. There are helpers available for this, so in the future we'd probably want to implement the helper callbacks instead of calling into our KMS implementation directly. v2: Make sure we take the mode_config mutex around modesetting, Also clear the initial framebuffer using vzalloc instead of vmalloc.

This commit reworks device initialization so that we always enable the FIFO at driver load, deferring SVGA enable until either first modeset or fbdev enable. This should always leave the fifo properly enabled for render- and control nodes. In addition, *) We disable the use of VRAM when SVGA is not enabled. *) We simplify PM support so that we only throw out resources on hibernate, not on suspend, since the device keeps its state on suspend.

Just a bit of OCD cleanup on headers - this function isn't the core interface any more but just a helper for drivers who haven't yet transitioned to universal planes.
