2016-03-08drm: introduce pipe color correction propertiesLionel Landwerlin
Patch based on a previous series by Shashank Sharma. This introduces optional properties to enable color correction at the pipe level. It relies on 3 transformations applied to every pixels displayed. First a lookup into a degamma table, then a multiplication of the rgb components by a 3x3 matrix and finally another lookup into a gamma table. The following properties can be added to a pipe : - DEGAMMA_LUT : blob containing degamma LUT - DEGAMMA_LUT_SIZE : number of elements in DEGAMMA_LUT - CTM : transformation matrix applied after the degamma LUT - GAMMA_LUT : blob containing gamma LUT - GAMMA_LUT_SIZE : number of elements in GAMMA_LUT DEGAMMA_LUT_SIZE and GAMMA_LUT_SIZE are read only properties, set by the driver to tell userspace applications what sizes should be the lookup tables in DEGAMMA_LUT and GAMMA_LUT. A helper is also provided so legacy gamma correction is redirected through these new properties. v2: Register LUT size properties as range v3: Fix round in drm_color_lut_get_value() helper More docs on how degamma/gamma properties are used v4: Update contributors v5: Rename CTM_MATRIX property to CTM (Doh!)

2016-03-08drm/atomic: Handle encoder stealing from set_config better.Maarten Lankhorst
Instead of failing with -EINVAL when conflicting encoders are found, the legacy set_config will disable other connectors when encoders conflict. With the previous commit this becomes a lot easier to implement. set_config only adds connectors to the state that are modified, and because of the previous commit that calls add_affected_connectors only on set->crtc it means any connector not part of the modeset can be stolen from. We disable the connector in that case, and possibly the crtc if required. Atomic modeset itself still doesn't allow encoder stealing, the results would be too unpredictable.

2016-03-02drm/dsi: Get DSI host by DT device nodeArchit Taneja
MIPI DSI devices are inherently aware of their host because they share a parent-child hierarchy in the device tree. Non-DSI drivers that create DSI device don't have this data. In order to get this information, they require to a phandle to the DSI host in the device tree. Maintain a list of all the DSI hosts that are currently registered. This list will be used to find the struct mipi_dsi_host corresponding to the device tree node passed to of_find_mipi_dsi_host_by_node().

2016-03-02drm/dsi: Add routine to unregister a DSI deviceArchit Taneja
A driver calling mipi_dsi_device_register_full() might want to remove the device once it's done. It might also require it in an error handling path in case something went wrong. Create mipi_dsi_device_unregister() for this purpose and use it within mipi_dsi_remove_device_fn() as it does the same thing.

2016-03-02drm/dsi: Try to match non-DT DSI devicesArchit Taneja
Add a device name field in struct mipi_dsi_device. This name is not the same as the device name (which is of the format "hostname.reg"). When the device is created via DT, this name is set to the modalias string. In the non-DT case, the driver creating the DSI device provides the name by populating a field in struct mipi_dsi_device_info. Matching for DT case would be as it was before. For the non-DT case, we compare the device and driver names. Other buses (like I2C/SPI) perform a non-DT match by comparing the device name and entries in the driver's id_table. Such a mechanism isn't used for the DSI bus. Reviewed-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Thierry Reding <treding@nvidia.com>
2016-03-02drm/dsi: Use mipi_dsi_device_register_full() for DSI device creationArchit Taneja
Use mipi_dsi_device_register_full() for device creation. This takes in a struct mipi_dsi_device_info as a template to populate the DSI device information. The reason to introduce this is to have a way to create DSI devices not available via DT. Drivers that want to create a DSI device can populate a struct mipi_dsi_device_info and call this function. For DSI devices available via DT, of_mipi_dsi_device_add() is used as before, but this now calls mipi_dsi_device_register_full() internally.

2016-02-19drm/atomic: Allow for holes in connector state, v2.Maarten Lankhorst
Because we record connector_mask using 1 << drm_connector_index now the connector_mask should stay the same even when other connectors are removed. This was not the case with MST, in that case when removing a connector all other connectors may change their index. This is fixed by waiting until the first get_connector_state to allocate connector_state, and force reallocation when state is too small. As a side effect connector arrays no longer have to be preallocated, and can be allocated on first use which means a less allocations in the page flip only path. Changes since v1: - Whitespace. (Ville) - Call ida_remove when destroying the connector. (Ville) - u32 alloc -> int. (Ville) Fixes: 14de6c44d149 ("drm/atomic: Remove drm_atomic_connectors_for_crtc.")

2016-02-12drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.Rafael Antognolli
This module is heavily based on i2c-dev. Once loaded, it provides one dev node per DP AUX channel, named drm_dp_auxN, where N is an integer. It's possible to know which connector owns this aux channel by looking at the respective sysfs /sys/class/drm_aux_dev/drm_dp_auxN/connector, if the connector device pointer was correctly set in the aux helper struct. Two main operations are provided on the registers read and write. The address of the register to be read or written is given using lseek. The seek position is updated upon read or write. v2: - lseek is used to select the register to read/write - read/write are used instead of ioctl - no blocking_notifier is used, just a direct callback v3: - use drm_dp_aux_dev prefix for public functions - chardev is named drm_dp_auxN - read/write don't allocate a buffer anymore, and transfer up to 16 bytes a time - remove notifier list from the implementation - option on menuconfig is now a boolean - add inline stub functions to avoid breakage when this option is disabled v4: - fix build system changes - actually disable this module when not selected. v5: - Use kref to avoid device closing while still in use - Don't use list, use an idr for storing aux_dev - Remove "connector" attribute - set aux.dev to the connector drm_connector device, instead of drm_device v6: - Use atomic_t for usage count - Use a mutex instead of spinlock for idr lock - Destroy chardev immediately on unregister - other minor suggestions from Ville v7: - style fixes - error handling fixes v8: - more error handling fixes v9: - remove module_init and module_exit, and add drm_dp_aux_dev_init/exit to drm_kms_helper_init/exit.

2016-02-08drm: Clean up pending events in the coreDaniel Vetter
There's really no reason to not do so, instead of replicating this for every use-case and every driver. Now we can't just nuke the events, since that would still mean that all drm_event users would need to know when that has happened, since calling e.g. drm_send_event isn't allowed any more. Instead just unlink them from the file, and detect this case and handle it appropriately in all functions. v2: Adjust existing kerneldoc too. v3: Improve wording of the kerneldoc and split out vblank cleanup (Laurent).

Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

2016-01-05drm/atomic-helper: Reject legacy flips on a disabled pipeDaniel Vetter
We want this for consistency with existing page_flip semantics. Since this spurred quite a discussion on IRC also document why we reject event generation when the pipe is off: It's not that it's hard to implement, but userspace has a track recording which proves that it's way too easy to accidentally abuse and cause havoc. We want to make sure userspace doesn't get away with that. v2: Somehow thought we do reject events already, but that code only existed in my imagination ... Also suggestions from Thierry.
