Code does read-modify-write but the read was outside the lock. It is fine since the caller holds struct mutex, but if we correct this we open up the opportunity for decreasing the mutex duration time since the call to ironlake_enable_drps does not need it any longer since it is covered by the mchdev_lock lock.

RPS lock must be taken before the struct_mutex to avoid locking inversion. So stop grabbing it for the whole powersave initialization and instead only take it during the sections which need it.

The fake agp driver for the intel graphics gart is only needed for ums support. And we ditched that a long time ago: commit 03dae59c Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Jul 23 16:27:25 2014 +0200 drm/i915: Ditch UMS config option With this there's no longer the problem that 2 drivers (fake agp driver and the drm/i915 driver) fight over the same piece, which fixes apparent dma leaks detected by CONFIG_DMA_API_DEBUG. Note that the leak isn't real since intel-gtt refcounts and will tear down eventually. But the debug code assumes that when the i915 driver unbinds from the pci device everything should be gone. Which isn't the case if we have intel-agp enabled - userspace might need it. But by ditching this intel-gtt setup and teardown is completely tied to the livetime of the "real" driver. While at it untangle the init ordering a bit - the fake agp wouldn't be initialized correctly if i915.ko loads first. Which isn't a problem since when i915 loads in kms mode you won't need the fake agp support needed by the ums driver ...

由 Daniel Vetter 提交于
The AGP_INTEL driver provides an interface for very old userspace to control the GART (though the GART itself was only ever emulated on Intel systems). The pci bridge discovery code is also used by the i915.ko driver to set up the GTT on old systems, but it does not require the old userspace interface. When i915.ko selects the old interface, it binds another user to the core GTT routines, and in particular creates a second reference to the scratch pages allocated. This hinders resource leak debugging for when we unload i915.ko as we want to assert that all DMA pages have been released, but we appear to leak because of the secondary interface which persists after i915.ko unloads. All i915.ko users do not require the old /dev/agpgart interface so stop selecting it and simplify our debugging by dropping the historical baggage. Note that by selecting AGP=n it was already possible to unselect AGP_INTEL. But since we've dropped support for any of the AGP stuff long ago there's really no point for this any more. Also note that we still need INTEL_GTT, which is the underlying, shared, driver for the graphics GART on gen1-5. v2: Entirely new commit message (Chris, Ville).

Swap the order of context & engine cleanup, so that contexts are cleaned up first, and *then* engines. This is a more sensible order anyway, but in particular has become necessary since the 'intel_ring_initialized() must be simple and inline' patch, which now uses ring->dev as an 'initialised' flag, so it can now be NULL after engine teardown. This in turn can cause a problem in the context code, which (used to) check the ring->dev->struct_mutex -- causing a fault if ring->dev was NULL. Also rename the cleanup function to reflect what it actually does (cleanup engines, not a ringbuffer), and fix an annoying whitespace issue. v2: Also make the fix in i915_load_modeset_init, not just in i915_driver_unload (Chris Wilson) v3: Had extra stuff in it. v4: Reverted extra stuff (so we're back to v2).

gmux is a microcontroller built into dual GPU MacBook Pros. On pre-retina MBPs, if we're the inactive GPU, we need apple-gmux to temporarily switch DDC so that we can probe the panel's EDID. The checks for CONFIG_VGA_ARB and CONFIG_VGA_SWITCHEROO are necessary because if either of them is disabled but gmux is present, the driver would never load, even if we're the active GPU. (vga_default_device() would evaluate to NULL and vga_switcheroo_handler_flags() would evaluate to 0.)
