2018-03-01drm: omapdrm: dss: Expose DSS data in a dss_device structureLaurent Pinchart
The anoonymous dss structure in dss.c is the top-level component in the omapdss driver. As such it should store all internal instance-specific data that is currently stored in global variables. This however requires both naming the structure to pass it around functions, and accessing it from various locations in the omapdss driver. While we could implement get and set functions for every field that needs to be accessed outside of dss.c, that would introduce overhead and complexity that we could avoid by exposing the structure to internal components of the omapdss driver. Do so to prepare for removal of global variables. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2018-03-01drm: omapdrm: Split init and cleanup from probe and remove functionsLaurent Pinchart
When merging the omapdrm and omapdss drivers there will be not omapdrm platform device anymore, and thus no associated probe and remove functions. To prepare for that, split all the initialization code from the probe function to make it usable without a platform device. Similarly, split the cleanup code from the remove function.

2018-03-01drm: omapdrm: dsi: Make wait_for_bit_change() return a statusLaurent Pinchart
The wait_for_bit_change() function returns the value of the bit it polls. This requires the caller to compare the return value to the expected bit value. As all the existing callers need is to check whether the bit has reached the expected value, it's easier to return a boolean status from the function.

2018-03-01drm: omapdrm: dss: Move initialization code from component bind to probeLaurent Pinchart
There's no reason to delay initialization of most of the driver (such as mapping memory I/O, getting clocks or enabling runtime PM) to the component master bind handler. This additionally fixes a real PM issue caused enabling runtime PM in the bind handler. The bind handler performs the following sequence of PM operations: pm_runtime_enable(dev); pm_runtime_get_sync(dev); ... (access the hardware to read the device revision) ... pm_runtime_put_sync(dev); If a failure occurs at this point, the error path calls pm_runtime_disable() to balance the pm_runtime_enable() call. To understand the problem, it should be noted that the bind handler is called when one of the component registers itself, which happens in the component's probe handler. Furthermore, as the components are children of the DSS, the device core calls pm_runtime_get_sync() on the DSS platform device before calling the component's probe handler. This increases the DSS power usage count but doesn't runtime resume the device, as runtime PM is disabled at that point. The bind handler is thus called with runtime PM disabled, with the device runtime suspended, but with the power usage count larger than 0. The pm_runtime_get_sync() call will thus further increase the power usage count and runtime resume the device. The pm_runtime_put_sync() handler will decrease the power usage count to a non-zero value and will thus not suspend the device. Finally, the pm_runtime_disable() call will disable runtime PM, preventing the pm_runtime_put() call in the device core from runtime suspending the device. The DSS device is thus left powered on. To fix this, move the initialization code from the bind handler to the probe handler.

2018-02-28drm/i915: Don't deref request->ctx inside unlocked print_request()Chris Wilson
Although we protect the request itself, we don't lock inside intel_engine_dump() and so the request maybe retired as we peek into it. One consequence is that the request->ctx may be freed before we dereference it, leading to a use-after-free. Replace the hw_id we are peeking from inside request->ctx with the request->fence.context, with which we can still track from which context the request originated (although to tie to HW reports requires a little more legwork, but is good enough to follow the GEM traces).

On pre-HSW we have dedicated hardware for the RGB limited range handling, and so we don't want to compress with the CSC matrix. Toss in a FIXME about gamma LUT vs. limited range using the CSC.

2018-02-28drm/i915: Remove the pointless 1:1 matrix copyVille Syrjälä
If we don't have to frob with the user provided ctm matrix there's no point in copying it over. Just point at the user ctm directly. Also the matrix gets fully populated by ctm_mult_by_limited() so no need to zero initialize it.

2018-02-28drm/uapi: The ctm matrix uses sign-magnitude representationVille Syrjälä
The documentation for the ctm matrix suggests a two's complement format, but at least the i915 implementation is using sign-magnitude instead. And looks like malidp is doing the same. Change the docs to match the current implementation, and change the type from __s64 to __u64 to drive the point home.

2018-02-28drm/i915: Enable VBT based BL control for DPMustamin B Mustaffa
Currently, BXT_PP is hardcoded with value '0'. It practically disabled eDP backlight on MRB (BXT) platform. This patch will tell which BXT_PP registers (there are two set of PP_CONTROL in the spec) to be used as defined in VBT (Video Bios Timing table) and this will enabled eDP backlight controller on MRB (BXT) platform. v2: - Remove unnecessary information in commit message. - Assign vbt.backlight.controller to a backlight_controller variable and return the variable value. v3: - Rebased to latest code base. - updated commit title.
