Spelling out _unlocked for each and every driver is a annoying. Especially if we consider how many drivers, do not know (or need to) about the horror stories involving struct_mutex. Just drop the suffix. It makes the API cleaner.

Vast majority of DRM (core and drivers) are struct_mutex free. As such we have only a handful of cases where the locked helper should be used. Make that stand out a little bit better.

Use the drm_gem_object_put_unlocked in the documentation for drm_gem_objects_lookup. The locked version of the helper should be used solely by people who know exactly what they are doing. Should prevent issues like ones adddressed with the next patch. Signed-off-by:

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:

The mgag200 supports a single pipeline with only a primary plane. It can be converted to simple KMS helpers. This also adds support for atomic modesetting. Wayland compositors, which use pageflip ioctls, can now be used with mgag200. v2: * prepare encoder and CRTC in a separate patch * remove suspend/resume code in a separate patch * don't call set_format_regs() in pipe_update() Signed-off-by:

Thomas Zimmermann authored
The MGA CRTC data structure struct mga_crtc contains unused additional fields; so it can removed. The standard DRM CRTC and encoder structures are embedded now in struct drm_simple_display_pipe. Done in preparation of converting mgag200 to simple KMS helpers. v3: * remove now-unused define MGAG200FB_CONN_LIMIT * remove unused define MATROX_DPMS_CLEARED Signed-off-by:

Registers are initialized with constants. This is now done in mgag200_init_regs(), mgag200_set_dac_regs() and mgag200_set_pci_regs(). Later patches should move these calls from mode setting to device initialization. v2: * replace uint8_t with u8 Signed-off-by:

The framebuffer's pitch is now set in mgag200_set_offset(). v2: * move offset and bpp-shift calculation into helper functions * use u8 instead of uint8_t * add MGAREG_CRTCEXT0_OFFSET_MASK Signed-off-by:

Set different fields in MISC in their rsp location in the code. This patch also fixes a bug in the original code where the mode's SYNC flags were never written into the MISC register. v2: * use u8 instead of uint8_t * define MGAREG_MISC_CLK_SEL_MASK Signed-off-by:

The function now only takes the device structure, and the old and new framebuffers. Signed-off-by:
-
Thomas Zimmermann authored
All register names and fields are now named according to the MGA programming manuals. The function doesn't need the CRTC, so callers pass in the device structure directly. The logging now uses device-specific macros. The original implementation busy-waited for the VSYNC flag to go up, to synchronize the page flip with the display's vblank. This code has been moved to mga_crtc_mode_set_base(). It's still present in the non-atomic code paths, but won't be used in atomic commits. With atomic, we should use interrupts to synchronize with vblanks. v3: * clarify commit message wrt. vblank busy-waiting v2: * use to_mga_device() * use MiB instead of MB * replace empty while loop with do-while, fixes checkpatch warning * replace uint{8,32}_t with u{8,32} Signed-off-by: -

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. Without HW support, compositors will use software rendering. Signed-off-by:

If videomode_from_timings() returns true, the mode allocated with drm_mode_create will be leaked. Also, the return value of drm_mode_create() is never checked, and thus could cause NULL deref. Fix these two issues. Signed-off-by:

The ti-sn65dsi86 MIPI DSI to eDP bridge chip supports arbitrary remapping of eDP lanes and also polarity inversion. Both of these features have been described in the device tree bindings for the device since the beginning but were never implemented in the driver. Implement both of them. Part of this change also allows you to (via the same device tree bindings) specify to use fewer than the max number of DP lanes that the panel reports. This could be useful if your display supports more lanes but only a few are hooked up on your board. Signed-off-by:
