2020-11-09drm/gem: Use struct dma_buf_map in GEM vmap ops and convert GEM backendsThomas Zimmermann1-3/+4
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. GEM VRAM helpers and qxl now use ttm_bo_vmap() et al. Amdgpu, nouveau and radeon use drm_gem_ttm_vmap() et al instead of implementing their own vmap callbacks. v7: * init QXL cursor to mapped BO buffer (kernel test robot) v5: * update vkms after switch to shmem v4: * use ttm_bo_vmap(), drm_gem_ttm_vmap(), et al.

2020-11-06drm/<drivers>: Constify struct drm_driverDaniel Vetter1-1/+1
Only the following drivers aren't converted: - amdgpu, because of the driver_feature mangling due to virt support. Subsequent patch will address this. - nouveau, because DRIVER_ATOMIC uapi is still not the default on the platforms where it's supported (i.e. again driver_feature mangling) - vc4, again because of driver_feature mangling - qxl, because the ioctl table is somewhere else and moving that is maybe a bit too much, hence the num_ioctls assignment prevents a const driver structure. - arcpgu, because that is stuck behind a pending tiny-fication series from me. - legacy drivers, because legacy requires non-const drm_driver. Note that for armada I also went ahead and made the ioctl array const.

2020-09-16drm/ast: Disable planes while switching display modesThomas Zimmermann1-0/+2
The ast HW cursor requires the primary plane and CRTC to display at a valid mode and format. This is not the case while switching display modes, which can lead to the screen turing permanently dark. As a workaround, the ast driver now disables active planes while the mode or format switch takes place. It also synchronizes with the vertical refresh to give CRTC and planes some time to catch up on each other. The active planes planes (primary or cursor) will be re-enabled by each plane's atomic_update() function. v3: * move the logic into the CRTC's atomic_disable function v2: * move the logic into the commit-tail function Signed-off-by: Thomas Zimmermann <[email protected]> Acked-by: Daniel Vetter <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-08-03drm/ast: Replace driver load/unload functions with device create/destroyThomas Zimmermann1-2/+4
The ast driver's load and unload functions are left-overs from when struct drm_driver.load/unload was still in use. The PCI probe helper allocated the DRM device and ran load to initialize it. This patch replaces this code with device create and destroy. The main difference is that the device's create function allocates the DRM device and ast structures in the same place. This will be required for switching ast to managed allocations.

2020-07-07drm/ast: Keep cursor HW BOs mappedThomas Zimmermann1-2/+3
Updating the image in a cursor's HW BO requires a mapping of the BO's buffer in the kernel's address space. Cursor image updates can happen frequently and create CPU overhead. As cursor HW BOs are small and never move, they are now map exactly once during the initialization and the mapping is used throughout the driver's lifetime. This change also removes a possible source of failures from ast_cursor_show(). As the helper does not establish mappings, it cannot fail. As a result, the cursor plane's atomic-update helper does not call any failable interfaces. All failures are detected before trying to update the cursor plane.

2020-07-07drm/ast: Replace ast_cursor_move() with ast_cursor_show()Thomas Zimmermann1-2/+2
Having a cursor move function is misleading, as it actually enables the cursor's image for displaying. So rename it to ast_cursor_show(). It's semantics is to show a cursor at the specified location on the screen. The displayed cursor is always the image in the cursor front BO. This change also simplifies struct ast_crtc to being a mere wrapper around around struct drm_crtc. It will be removed by a later patch.

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.

2017-08-02drm/ast: Actually load DP501 firmware when requiredEgbert Eich1-2/+1
The ast driver has a code to load the DP501 firmware, but it's never used. This patch implements its actual usage by requesting the firmware on demand, and release the firmware at exit as well. Also the path contains a few cleanups and makes relevant functions static.

2017-02-28drm/ast: Base support for AST2500Y.C. Chen1-0/+2
Add detection and mode setting updates for AST2500 generation chip, code originally from Aspeed and slightly reworked for coding style mostly by Ben. This doesn't contain the BMC DRAM POST code which is in a separate patch. Signed-off-by: Y.C.

2017-02-28drm/ast: Handle configuration without P2A bridgeRussell Currey1-1/+5
The ast driver configures a window to enable access into BMC memory space in order to read some configuration registers. If this window is disabled, which it can be from the BMC side, the ast driver can't function. Closing this window is a necessity for security if a machine's host side and BMC side are controlled by different parties; i.e. a cloud provider offering machines "bare metal". A recent patch went in to try to check if that window is open but it does so by trying to access the registers in question and testing if the result is 0xffffffff. This method will trigger a PCIe error when the window is closed which on some systems will be fatal (it will trigger an EEH for example on POWER which will take out the device). This patch improves this in two ways: - First, if the firmware has put properties in the device-tree containing the relevant configuration information, we use these. - Otherwise, a bit in one of the SCU scratch registers (which are readable via the VGA register space and writeable by the BMC) will indicate if the BMC has closed the window. This bit has been defined by Y.C Chen from Aspeed. If the window is closed and the configuration isn't available from the device-tree, some sane defaults are used. Those defaults are hopefully sufficient for standard video modes used on a server.
