2019-11-14drm/print: convert debug category macros into an enumJani Nikula

2019-11-09drm/mcde: dsi: Enable clocks in pre_enable() instead of mode_set()Stephan Gerhold
The DSI initialization sequence incorrectly assumes that the mode_set() function of the DRM bridge is always called when (re-)enabling the display. This is not necessarily the case. Keeping the device idle in the framebuffer console for a while results in the display being turned off using the disable() function. However, as soon as any key is pressed only (pre_)enable() are called. mode_set() is skipped because the mode has not been changed. In this case, the DSI HS/LP clocks are never turned back on, preventing the display from working. Fix this by moving a part of the initialization sequence from mode_set() to pre_enable(). Keep most of the video mode setup in mode_set() since most of the registers are only dependent on the mode that is set for the panel - there is no need to write them again each time we re-enable the display.

2019-11-09drm/mcde: dsi: Fix duplicated DSI connectorStephan Gerhold
Using a (single) DSI display with MCDE currently results in two "connected" connectors: Connector: DSI-1 id : 34 encoder id : 0 conn : connected size : 0x0 (mm) count_modes : 0 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Connector: DSI-2 id : 35 encoder id : 33 conn : connected size : 53x89 (mm) count_modes : 1 count_props : 5 props : 1 2 5 6 4 count_encoders : 1 encoders : 33 Mode: "480x800" 480x800 60 Although both show up as connected, the first one does not have any size and no available modes. This confuses userspace tools (e.g. kmscube) who look for available modes for the first connector. The reason for the duplicated connector is that mcde_dsi.c and the DRM panel bridge helper both set up a DSI connector, with more or less the same code. The connector set up by the DRM panel bridge is the one that is correctly set up in the example above. Therefore we can just remove the connector setup from mcde_dsi.c and let the DRM core handle all the hard work.

The MCDE driver differentiates only between "te_sync" (for hardware TE0 sync) and software sync (i.e. manually triggered updates) at the moment. However, none of these options work correctly for video mode panels. Therefore, we need to make some changes to make them work correctly: - Select hardware sync coming from the (DSI) formatter. - Keep the FIFO permanently enabled (otherwise MCDE will stop feeding data to the panel). - Skip manual software sync (this is not necessary in video mode).

Udl's GEM code and the generic SHMEM are almost identical. Replace the former with SHMEM. The dmabuf support in udl is being replaced with generic GEM PRIME functions.

Memory pages of locally created buffer objects are mmap'ed with caching enabled.

2019-11-08drm/udl: Remove flags field from struct udl_gem_objectThomas Zimmermann
The flags field in struct udl_gem controls mapping parameters: cached access for local buffers, write-combined access for imported buffers. We can drop the field and distinguish both cases by testing whether struct drm_gem_object.import_attach is NULL.

2019-11-08drm/ast: Enable atomic modesettingThomas Zimmermann
This commit sets the remaining atomic-modesetting helpers and the flag DRIVER_ATOMIC. Legacy cursor functions are removed in favor of the cursor plane. For power management, atomic helpers replace the indvidual operations that the driver currently runs. Atomic modesetting is enabled with this commit.

2019-11-08drm/ast: Add cursor planeThomas Zimmermann
The cursor plane uses an internal format of ARGB4444. To userspace, we announce ARGB8888 and do the transformation internally. v2: * don't set plane call-back functions to NULL explicitly * define plane format array in global scope Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191107083404.6852-9-tzimmermann@suse.de
2019-11-08drm/ast: Add CRTC helpers for atomic modesettingThomas Zimmermann
As the CRTC code has already been prepared for a split between mode setting and plane handling, most of the CRTC's atomic modesetting is build upon primitives of the non-atomic implementation.

2019-11-08drm/ast: Add primary planeThomas Zimmermann
Like the original mode-setting code, the primary plane supports XRGB888, RGB565 and C8. The plane itself only pins BOs and sets the base address and scanline offset. The mode-setting code will be located in the CRTC's atomic helpers. v2: * don't set plane call-back functions to NULL explicitly * define plane format array in global scope Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191107083404.6852-7-tzimmermann@suse.de
2019-11-08drm/ast: Split ast_set_vbios_mode_info()Thomas Zimmermann
The implementation of ast_set_vbios_mode() converts a DRM display mode and framebuffer into an adjusted mode and stores information for the video BIOS to several scratch regsiters. Here we split the function into individual functions that do the conversion, set the VBIOS mode information and format information. This makes it compatible with support for primary planes and atomic modesetting.

2019-11-08drm/ast: Split ast_set_ext_reg() into color and threshold functionThomas Zimmermann
In ast_set_ext_reg() sets several framebuffer options and CRT threshold parameters. The former is mostly state of the primary plane; the latter is constant. Hence, split the function in two and make it work with atomic modesetting.
