While VGA hotplugging worked(ish) before, it looks like that was mainly because we'd unintentionally enable it in valleyview_crt_detect_hotplug() when we did a force trigger. This doesn't work reliably enough because whenever the display powerwell on vlv gets disabled, the values set in VLV_ADPA get cleared and consequently VGA hotplugging gets disabled. This causes bugs such as one we found on an Intel NUC, where doing the following sequence of hotplugs: - Disconnect all monitors - Connect VGA - Disconnect VGA - Connect HDMI Would result in VGA hotplugging becoming disabled, due to the powerwells getting toggled in the process of connecting HDMI. Changes since v3: - Expose intel_crt_reset() through intel_drv.h and call that in vlv_display_power_well_init() instead of encoder->base.funcs->reset(&encoder->base); Changes since v2: - Use intel_encoder structs instead of drm_encoder structs Changes since v1: - Instead of handling the register writes ourself, we just reuse intel_crt_detect() - Instead of resetting the ADPA during display IRQ installation, we now reset them in vlv_display_power_well_init() Cc: stable@vger.kernel.org Acked-by:

Some hardware requires a valid render context before it can initiate rc6 power gating of the GPU; the default state of the GPU is not sufficient and may lead to undefined behaviour. The first execution of any batch will load the "golden render state", at which point it is safe to enable rc6. As we do not forcibly load the kernel context at resume, we have to hook into the batch submission to be sure that the render state is setup before enabling rc6. However, since we don't enable powersaving until that first batch, we queued a delayed task in order to guarantee that the batch is indeed submitted. v2: Rearrange intel_disable_gt_powersave() to match. v3: Apply user specified cur_freq (or idle_freq if not set). v4: Give in, and supply a delayed work to autoenable rc6 v5: Mika suggested a couple of better names for delayed_resume_work v6: Rebalance rpm_put around the autoenable task Signed-off-by:

Dell XPS 13 9350 apparently doesn't like it when we use the panel type from OpRegion. The OpRegion panel type (0) tells us to use use low vswing for eDP, whereas the VBT panel type (2) tells us to use normal vswing. The problem is that low vswing results in some display flickers.

intel_lrc.c has a table of "logical rings" (meaning engines), while intel_ringbuffer.c has separately open-coded initialisation for each engine. We can deduplicate this somewhat by using the same first-stage engine-setup function for both modes. So here we expose the function that transfers information from the static table of (all) known engines to the dev_priv->engine array of engines available on this device (adjusting the names along the way) and then embed calls to it in both the LRC and the legacy-mode setup.

Prior to gen6 we didn't have per-ring IMR registers, which means that since commit 61ff75ac ("drm/i915: Simplify enabling user-interrupts with L3-remapping") we're now masking off all interrupts when init_render_ring() gets called.

Let's ensure that we cannot run indefinitely without the hangcheck worker being queued. We removed it from being kicked on every request because we were kicking it a few millions times in every hangcheck interval and only once is necessary!

Never go to sleep waiting on the GPU without first ensuring that we will get woken up. We have a choice of queuing the hangcheck before every schedule() or the first time we wakeup. In order to simply accommodate both the signaler and the ordinary waiter, move the queuing to the common point of enabling the irq. We lose the paranoid safety of ensuring that the hangcheck is active before the sleep, but avoid code duplication (and redundant hangcheck queuing).

One of the numerous VT-d workarounds we require is that the display hardware reads past the end of the buffer triggering VT-d faults. This is acknowledged in the code as being safe "since we fill the unused portions of the GGTT with the scratch page". Alas, that is no longer always true and so we trigger DMAR read faults. Skylake also requires another workaround to avoid mixing VT-d and unpopulated PTE, and so there we also need to ensure we fill unused entries with the scratch page. Reported-by:

Move the encoder cloning check to happen earlier in the modeset. The main benefit will be that the debug output from a failed modeset will be less confusing as output_types can not indicate an invalid configuration during the later computation stages. For instance, what happened to me was kms_setmode was attempting one of its invalid cloning checks during which it asked for DP+VGA cloning on HSW. In this case the DP .compute_config() was executed after the FDI .compute_config() leaving the DP link clock (1.62 in this case) in port_clock, and then later the FDI BW computation tried to use that as the FDI link clock (which should always be 2.7). 1.62 x 2 wasn't enough for the mode it was trying to use, and so it ended up rejecting the modeset, not because of an invalid cloning configuration, but because of supposedly running out of FDI bandwidth. Took me a while to figure out what had actually happened. Signed-off-by:
