2021-02-08drm/mgag200: Move vmap out of commit tailThomas Zimmermann
Vmap operations may acquire the dmabuf reservation lock, which is not allowed within atomic commit-tail functions. Therefore move vmap and vunmap from the damage handler into prepare_fb and cleanup_fb callbacks. The mapping is provided as GEM shadow-buffered plane. The functions in the commit tail use the pre-established mapping for damage handling.

2020-11-09drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backendsThomas Zimmermann
This patch replaces the vmap/vunmap's use of raw pointers in GEM object functions with instances of struct dma_buf_map. GEM backends are converted as well. For most of them, this simply changes the returned type. TTM-based drivers now return information about the location of the memory, either system or I/O memory.

This patch adds support for G200 desktop cards. We can reuse the whole memory and modesetting code. A few PCI and DAC register values have to be updated accordingly. The most significant change is in the PLL setup. The driver parses the device's BIOS to retrieve clock limits and reference clocks.

So far, PCI option registers were initialized as part of modesetting, which is late in the process. As these registers control fundamental operation, they should be set early. The patch moves the PCI option handling into device register setup, before even the device MMIO memory is being mapped. No functional changes made.

2020-05-19drm/mgag200: Replace VRAM helpers with SHMEM helpersThomas Zimmermann
The VRAM helpers managed the framebuffer memory for mgag200. This came with several problems, as some MGA device require the scanout address to be located at VRAM offset 0. It's incompatible with the page-flip semantics of DRM's atomic modesettting. With atomic modesetting, old and new framebuffers have to be located in VRAM at the same time. So at least one of them has to reside at a non-0 offset. This patch replaces VRAM helpers with SHMEM helpers. GEM SHMEM buffers reside in system memory, and are shadow-copied into VRAM during page flips. The shadow copy always starts at VRAM offset 0. v2: * revert dev->pdev changes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: John Donnelly <John.p.donnelly@oracle.com> Acked-by: Emil Velikov <emil.velikov@collabora.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200515083233.32036-16-tzimmermann@suse.de

2020-05-11drm/mgag200: Convert struct drm_device to struct mga_device with helperThomas Zimmermann
Mgag200 uses dev_private to look up struct mga_device for instances of struct drm_device. Use of dev_private is deprecated, so hide it in the helper function to_mga_device(). v2: * make to_mga_device() a function (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200507090315.21274-2-tzimmermann@suse.de

2019-10-04drm/mgag200: Reserve video memory for cursor planeThomas Zimmermann
The double-buffered cursor image is currently stored in video memory by creating two BOs and pinning them to VRAM. The exact location is chosen by VRAM helpers. The pinned cursor BOs can conflict with framebuffer BOs and prevent the primary plane from displaying its framebuffer. As a first step to solving this problem, we reserve dedicated space at the high end of the video memory for the cursor images. As the amount of video memory now differs from the amount of available framebuffer memory, size tests are adapted accordingly.

So moving it a common place and sharing between atomic and non-atomic drivers.

2019-07-09drm/mgag200: Replace struct mga_fbdev with generic framebuffer emulationThomas Zimmermann
This patch replaces mgag200'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 mga_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. For consistency, this patch also changes the preferred framebuffer depth. The original code used 24 bpp by default and 32 bpp for the framebuffer. As 24 bpp is not well supported by userspace anyway, setting 32 bpp as default makes sense. v2: * rely on fbdev helpers error messages * document changes to preferred depth * 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/315832/
