The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

It turns out that USB3 controller failed to awaken when plugging in the USB3 cardreader. Further experiments found that the USB3 host controller can only be awakened via polling, not via PME interrupt. But if the PCIe port to which the USB3 host controller is connected is suspended, we cannot poll the controller because its config space is not accessible when the PCIe port is in a low power state. To solve the issue, the PCIe port will not be suspended if any subordinate device needs PME polling.

To avoid leaky abstractions (by either depending upon implementation details of said helper wrt to preallocations, or reimplementing it in our code and so fuzzing around in internal details of that helpr) simply disable the shrinker lock stealing accross calls into the helper functions. This should fix igt/gem_tiled_swapping. v2: Fix cleanup path confusion bemoaned by Chris Wilson.

But this also caused the requirement that every place which allocates memory needs to be careful about the gem state of objects, since the shrinker could have pulled the rug out from under it. We've usually solved this by carefully preallocating things or ensure that buffers are pinned already. But the shrinker also reaps mmap offset, so allocating those needs to be careful, too. Now that code has been factored out into some common helpers, so either we have fragile code depending upon the common helper not doing something we don't want it to do. Or we need to reimplement the mmap offset creation and so also leak implementation details into our code. Since this all results in leaky abstraction, cop out by disabling the lock borrowing trick while calling down into the helpers. That way our craziness is nicely confined to files in drm/i915. v2: Split out the change to create_mmap_offset as request by Chris Wilson.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some broken systems (like HP nc6120) in some cases, usually after LID close/open, enable VGA plane, making display unusable (black screen on LVDS, some strange mode on VGA output). We used to disable VGA plane only once at startup. Now we also check, if VGA plane is still disabled while changing mode, and fix that if something changed it.

| | * | drm/i915: Preallocate the drm_mm_node prior to manipulating the GTT drm_mm ↵Chris Wilson2012-12-181-37/+25

To accomplish this, we can simply allocate the drm_mm_node up front and then use the combined search & insert drm_mm routines, reducing our code footprint in the process.
