Make resume/on codepath not to wait for panel_power_cycle_delay(t11_t12) if this time is already spent in suspend/poweron time. v2: Use CLOCK_BOOTTIME and remove jiffies for panel power cycle delay calculation(Ville). v3: Addressed below comments 1. Tracking time from where last powercycle is initiated. 2. Used ktime_get_bootime() wrapper for boottime clock. 3. Used ktime_ms_delta() to get time difference. v4: Updated v3 change log in detail. v5: Removed static from panel_power_on_time(Stéphane).

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 ... Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=93793Signed-off-by:

While running some tests on the scheduler patches with rpm enabled I came across a corruption in the ringbuffer, which was root-caused to the GPU being suspended while commands were being emitted to the ringbuffer. The access to memory was failing because the GPU needs to be awake when accessing stolen memory (where my ringbuffer was located). Since we have this constraint it looks like a sensible idea to check that we hold a refcount when we access the rungbuffer. v2: move the check from ring_begin to ringbuffer iomap time (Chris) v3: update comment (Chris) Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by:

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).

We accidentally point both cfgcr registers for the second shared DPLL to the same location in i915_reg.h. This results in a lot of hw pipe state mismatches whenever we try to do a modeset that requires allocating the DPLL to a CRTC: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in dpll_hw_state.cfgcr1 (expected 0x80000168, found 0x000004a5) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in base.adjusted_mode.crtc_clock (expected 108000, found 49500) [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in port_clock (expected 108000, found 49500) This usually ends up causing blank monitors, since the DPLL never can get set to the right clock.

The pre-retina MacBook Pro uses an LVDS panel and a gmux controller to switch the panel between its two GPUs. The panel mode in VBIOS is notoriously bogus on these machines. Use drm_get_edid_switcheroo() in lieu of drm_get_edid() on LVDS if the vga_switcheroo handler is capable of temporarily switching the panel's DDC lines to the discrete GPU. This allows us to retrieve the EDID if the panel is currently muxed to the integrated GPU. This only enables EDID probing on the pre-retina MBP (2008 - 2013).
