This patch adds the ability to override the typical display timing for a given panel. This is useful for devices which have timing constraints that do not apply across the entire display driver (eg: to avoid crosstalk between panel and digitizer on certain laptops). The rules are as follows: - panel must not specify fixed mode (since the override mode will either be the same as the fixed mode, or we'll be unable to check the bounds of the overried) - panel must specify at least one display_timing range which will be used to ensure the override mode fits within its bounds Changes in v2: - Parse the full display-timings node (using the native-mode) (Rob) Changes in v3: - No longer parse display-timings subnode, use panel-timing (Rob) Changes in v4: - Don't add mode from timing if override was specified (Thierry) - Add warning if timing and fixed mode was specified (Thierry) - Don't add fixed mode if timing was specified (Thierry) - Refactor/rename a bit to avoid extra indentation from "if" tests - i should be unsigned (Thierry) - Add annoying WARN_ONs for some cases (Thierry) - Simplify 'No display_timing found' handling (Thierry) - Rename to panel_simple_parse_override_mode() (Thierry) Changes in v5: - Added Heiko's Tested-by Changes in v6: - Rebased to drm-misc next - Added tags Cc: Doug Anderson <dianders@chromium.org> Cc: Eric Anholt <eric@anholt.net> Cc: Heiko Stuebner <heiko@sntech.de> Cc: Jeffy Chen <jeffy.chen@rock-chips.com> Cc: Rob Herring <robh+dt@kernel.org> Cc: Stéphane Marchesin <marcheu@chromium.org> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: devicetree@vger.kernel.org Cc: dri-devel@lists.freedesktop.org Signed-off-by:

When vkms invoke drm_universal_plane_init(), it sets 0 for possible_crtcs parameter which means that planes can't be attached to any CRTC. It currently works due to some safeguard in the drm_crtc file; however, it is possible to identify the problem by trying to append a second connector. This patch fixes this issue by modifying vkms_plane_init() to accept an index parameter which makes the code a little bit more flexible and avoid set zero to possible_crtcs. Signed-off-by:

Only dynamic mode objects, i.e. those which are refcounted and have a free callback, can be added while the overall drm_device is visible to userspace. All others must be added before drm_dev_register and removed after drm_dev_unregister. Small issue around drivers still using the load/unload callbacks, we need to make sure we set dev->registered so that load/unload code in these callbacks doesn't trigger false warnings. Only a small adjustement in drm_dev_register was needed. Motivated by some irc discussions about object ids of dynamic objects like blobs become invalid, and me going on a bit an audit spree.

The function drm_client_close is declared as static and marked as EXPORT_SYMBOL. It's a bit confusing for an internal function to be exported. The area of visibility for such function is its .c file and all other modules. Other *.c files of the same module can't use it, despite all other modules can. Relying on the fact that this is the internal function and it's not a crucial part of the API, the patch removes the EXPORT_SYMBOL marking of drm_client_close. Signed-off-by:

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:

The bochs driver (and virtual hardware) requires buffer objects to reside in video ram to display them to the screen. So it can not display the framebuffer console because the respective buffer object is permanently pinned in system memory. Using a shadow buffer for the console solves this problem. The console emulation will pin the buffer object only during updates from the shadow buffer. Otherwise, the bochs driver can freely relocated the buffer between system memory and video ram. v2: * select shadow FB via struct drm_mode_config.prefer_shadow_fbdev Signed-off-by:

Generic framebuffer emulation uses a shadow buffer for framebuffers with dirty() function. If drivers want to use the shadow FB without such a function, they can now set prefer_shadow or prefer_shadow_fbdev in their mode_config structures. The former flag is exported to userspace, the latter flag is fbdev-only. v3: * only schedule dirty worker if fbdev uses shadow fb * test shadow fb settings with boolean operators * use bool for struct drm_mode_config.prefer_shadow_fbdev * fix documentation comments Signed-off-by:

This patch changes DRM clients to not map the buffer by default. The buffer, like any buffer object, should be mapped and unmapped when needed. An unmapped buffer object can be evicted to system memory and does not consume video ram until displayed. This allows to use generic fbdev emulation with drivers for low-memory devices, such as ast and mgag200. This change affects the generic framebuffer console. HW-based consoles map their console buffer once and keep it mapped. Userspace can mmap this buffer into its address space. The shadow-buffered framebuffer console only needs the buffer object to be mapped during updates. While not being updated from the shadow buffer, the buffer object can remain unmapped. Userspace will always mmap the shadow buffer. v2: * change DRM client to not map buffer by default * manually map client buffer for fbdev with HW framebuffer Signed-off-by:

DRM clients, such as the fbdev emulation, have their buffer objects mapped by default. Mapping a buffer implicitly prevents its relocation. Hence, the buffer may permanently consume video memory while it's allocated. This is a problem for drivers of low-memory devices, such as ast, mgag200 or older framebuffer hardware, which will then not have enough memory to display other content (e.g., X11). This patch introduces drm_client_buffer_vmap() and _vunmap(). Internal DRM clients can use these functions to unmap and remap buffer objects as needed. There's no reference counting for vmap operations. Callers are expected to either keep buffers mapped (as it is now), or call vmap and vunmap in pairs around code that accesses the mapped memory. v2: * remove several duplicated NULL-pointer checks v3: * style and typo fixes Signed-off-by:

The current possible_clones setup doesn't look sensible. I'm assuming the 0 and 1 are supposed to refer to the indexes of the hdmi and hda encoders? So it kinda looks like we want hda+hdmi cloning, but then dvo also claims to be cloneable with hdmi, but hdmi won't recipricate. Benjamin tells me all encoders should be cloneable with each other, so let's fix up the masks to indicate that.

Convert the common panel bindings to DT schema consolidating scattered definitions to a single schema file. The 'simple-panel' binding just a collection of properties and not a complete binding itself. All of the 'simple-panel' properties are covered by the panel-common.txt binding with the exception of the 'no-hpd' property, so add that to the schema. As there are lots of references to simple-panel.txt, just keep the file with a reference to common.yaml for now until all the bindings are converted.
