2020-08-03drm/mgag200: Add support for G200 desktop cardsThomas Zimmermann
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. With no BIOS found, safe defaults are being used. v2: * copy BIOS ROM to system memory and access with regular load/store; resolves potential HW limitations * fix some stray whitespaces Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Co-developed-by: Egbert Eich <eich@suse.com> Signed-off-by: Egbert Eich <eich@suse.com> Co-developed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Takashi Iwai <tiwai@suse.de> Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200730102844.10995-9-tzimmermann@suse.de

2020-08-03drm/mgag200: Initialize PCI registers early during device setupThomas Zimmermann
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. Moving the PCI code next to the device-register setup also allows to remove the has_sdram field from struct mga_device. The state is now local to the init helper.

2020-06-11drm/mgag200: Embed instance of struct drm_device in struct mga_deviceThomas Zimmermann
Following current best practice, the instance of struct drm_device is now embedded in struct mga_device. The respective field has been renamed from 'dev' to 'base' to reflect the relationship. Conversion from DRM device is done via upcast. Using dev_private is no longer possible. The patch also open-codes drm_dev_alloc() and DRM device initialization is now performed by a call to drm_device_init().

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

2020-05-19drm/mgag200: Remove HW cursorThomas Zimmermann
The HW cursor of Matrox G200 cards only supports a 16-color palette format. Univeral planes require at least ARGB or a similar component- based format, so remove the HW cursor. Alternatively, the driver could dither a cursor image from ARGB to 16 colors. But this does not produce pleasent-looking results in general, so it's useless for modern compositors.

2019-05-15drm/mgag200: Convert mgag200 driver to VRAM MMThomas Zimmermann
The data structure |struct drm_vram_mm| and its helpers replace mgag200's TTM-based memory manager. It's the same implementation; except for the type names. v4: * don't select DRM_TTM or DRM_VRAM_MM_HELPER v3: * use drm_gem_vram_mm_funcs * convert driver to drm_device-based instance v2: * implement mgag200_mmap() with drm_vram_mm_mmap() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-16-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2019-03-19drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constantThomas Zimmermann
Most TTM drivers define the constant DRM_FILE_PAGE_OFFSET of the same value. The only exception is vboxvideo, which is being converted to the new offset by this patch. Unifying the constants in a single place simplifies the driver code.

2017-08-04drm: mgag200: remove dead code and pointless local lut storagePeter Rosin
The redundant fb helpers .load_lut, .gamma_set and .gamma_get are no longer used. Remove the dead code and hook up the crtc .gamma_set to use the crtc gamma_store directly instead of duplicating that info locally.

The integer returned by the unload hook is ignored by the drm core, so let's make it void.

2016-12-18drm: Don't include <drm/drm_encoder.h> in <drm/drm_crtc.h>Laurent Pinchart
<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of <drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not needed in the header. <drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.
