The purpose is to make the code much easier to read and therefore reduce the possibility for bugs. A side effect is that it also makes it much easier for the compiler, reducing the object size by 4k -- from just a few functions! Signed-off-by: -

Refactor the common code into seperate functions and use the MIN(large, small) buffer calculation for self-refresh watermarks. Signed-off-by: -

We need to track different state on each generation in order to detect when we need to refresh the FBC registers. Signed-off-by: -

Thermal reporting may not be enabled by default on some machines, so enable the appropriate bits to allow IPS to get the data it needs from the CPU thermal device. Signed-off-by:

TU size is only part of the M1 and M2 regs, not the N regs. This keeps us from overwriting a reserved field. Signed-off-by:

eDP panels require these to be set up prior to panel power sequencing, or they'll fail to power on due to an "asset not ready" check. And of course, eDP panels attached to anything other than DP_A need them enabled regardless, since they'll be driven from the CPU through FDI out to the PCH. Signed-off-by:

This way we can also use it in CRTC prepare/commit. Also makes it easier to split out FDI and other code. Signed-off-by:

create_singlethreaded_workqueue() is being phased out for a new concurrency managed task infrastructure. Adapt our workqueue constructor to explicitly create a domain that only allows the execution of a single task at any time. All the tasks are expected to require the dev->struct_mutex, so would block concurrency of other tasks if we allow more than a single i915 task to be run at once. Signed-off-by: -

We don't know how to enable it safely, especially as outputs turn on and off. When disabling LP1 we also need to make sure LP2 and 3 are already disabled. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=29173 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=29082Reported-by:

Currently we have a exact mapping of a connector onto an encoder for its whole lifetime. Make this an explicit property of the structure and so simplify the code. Signed-off-by:

If we are busy, then we may have woken up the wait_request handler but not yet serviced it before the hang check fires. So in hang check, double check that the i915_gem_do_wait_request() is still pending the wake-up before declaring all hope lost. Fixes regression with e78d73b1.

Otherwise we may not be able to train the DP link. Signed-off-by:

When turning on or off the VDD AUX bit, we need to give the panel time to start or stop or AUX transactions may fail. Signed-off-by:

Jesse Barnes authored
Mode set sequence outlines when the AUX VDD bit should be set and cleared, and it's separate from the panel power sequence. Signed-off-by:
-
Jesse Barnes authored
Mode set sequence requires that we start training, then enable the panel, then complete training. So split the DP training function into two parts; the first enables the DP port and sets training pattern 1 and the second completes the training. As part of this, remove some redundant function args from the various DP handling functions and use the intel_dp fields everywhere we can. Signed-off-by:

Jesse Barnes authored
Mode setting sequence specifies that we use VDD AUX for configuration and detection, and early in the mode set sequence. Only later (after DP_A has started training) should we actually enable panel power. Signed-off-by:

snprintf() returns the number of bytes which would have been used if there was enough space. It can be larger than the size of the buffer. Obviously in this case the buffer is large enough but everyone just copy and pastes this code so it's better to limit it and set a good example. Signed-off-by:

Use the detection from intel-gtt.ko instead. Hooray! Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem. v2: Chris Wilson noted that my error handling was crap. Fix it. He also said that this fixes a problem on his i845. Indeed, i915_probe_agp misses a special case for i830/i845 stolen mem detection.

This way create_gatt_table become dummy glue functions for the fake agp driver - rename them accordingly (and kill the now unnecessary i9xx copy). With this change, the gtt initialization code is almost independant from the agp stuff. Two things are still missing: - the scratch page is created by the generic agp code. - filling the whole gtt with scratch_page ptes is not yet consolidated - this needs abstracted pte handling, first.

The only difference between i915 and i965 was the calculation of the gtt address. So merge these two paths into one. Otherwise the same changes as in the i830 setup consolidation. Signed-off-by:

Slighlty reordered sequence was necessary. Also don't set agp_bridge->gatt_bus_addr anymore. Only used by generic agp helper functions, hence unnecessary for the intel fake agp driver. Signed-off-by:
