In order to avoid keeping a reference on the i915_vma (which is long overdue!) we have to coordinate all the possible lifetimes and only use the vma while we know it is alive. In this episode, we are reminded that while idle, the closed vma are destroyed. So if the GT idles while we are working with the vma, the vma itself becomes invalid. First class i915_vma here we come, but in the meantime keep piling on the straw. Signed-off-by:

Let's move handling and reset for gen11 display IRQs to their own functions, similar to how we deal with GT interrupts. This will make the top-level functions a bit easier to read and potentially make things easier to deal with in the future if new platforms wind up needing different display handling logic.

Rather than assume if and only if the engine->default_state is not set that the context is invalid, instead track when we know the context has valid state -- either because we have copied the default_state or we have completed a context switch to save the HW state. Signed-off-by:

Only along the submission path can we guarantee that the locked request is indeed from a foreign engine, and so the nesting of engine/rq is permissible. On the submission tasklet (process_csb()), we may find ourselves competing with the normal nesting of rq/engine, invalidating our nesting. As we only use the spinlock for debug purposes, skip the debug if we cannot acquire the spinlock for safe validation - catching 99% of the bugs is better than causing a hard lockup. Signed-off-by:

As the i915_active.retire() may be running on another CPU as we detect that the i915_active is idle, we may not wait for the retirement itself. Wait for the remote callback by waiting for the retirement worker. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=112424Signed-off-by:

Similar to for i915_active.mutex, we require each class of i915_active to have distinct lockdep chains as some, but by no means all, i915_active are used within the shrinker and so have much more severe usage constraints. By using a lockclass local to i915_active_init() all i915_active workers have the same lock class, and we may generate false positives when waiting for the i915_active. If we push the lockclass into the caller, each class of i915_active will have distinct lockdep chains. Signed-off-by:

Avoid dangerous race handling of destroyed vma by unbinding all vma instead. Unfortunately, this stops us from trying to be clever and only doing the minimal change required, so on first use of scanout we may encounter an annoying stall as it transitions to a new cache level.

Quite simply we only need to check for prior corruption on enabling rc6 on module load and resume, so by hooking into the common entry points. Signed-off-by:

The unaligned ioread32() will make us read byte by byte looking for the vbt. We could just as well have done a ioread8() + a shift and avoid the extra confusion on how we are looking for "$VBT". However when using ACPI it's guaranteed the VBT is 4-byte aligned per spec, so we can probably assume it here as well. v2: do not try to simplify the loop by eliminating the auxiliary counter (Jani and Ville) Signed-off-by:

We don't need to keep the pci rom mapped during the entire intel_bios_init() anymore. Move it to the previous copy_vbt() function and rename it to oprom_get_vbt() since now it's responsible to to all operations related to get the vbt from the oprom. v2: fix double __iomem attribute detected by sparse v3: fix missing unmap on success (Ville) Signed-off-by:

When we map the VBT through pci_map_rom() we may not be allowed to simply discard the address space and go on reading the memory. That doesn't work on my test system, but by dumping the rom via sysfs I can can get the correct vbt. So change our find_vbt() to do the same as done by pci_read_rom(), i.e. use memcpy_fromio(). v2: the just the minimal changes by not bothering with the unaligned io reads: this can be done on top (from Ville and Jani) v3: drop const in function return since now we are copying the vbt, rather than just finding it Signed-off-by:

eDP specification states that sink can have its PSR capability changed, I have never found any panel doing that but lets add that for completeness. For now it is not reading back the PSR capabilities and if possible re-enabling PSR, this will be added if a panel is found using this feature. v4: Cleaning DP_PSR_CAPS_CHANGE Reviewed-by:

eDP spec states that when sink enconters a problem that prevents it to keep PSR running it should set PSR status to internal error and set the reason why it happen to PSR_ERROR_STATUS but it is not how it was implemented. But also I don't want to change this behavior, who knows if there is a panel out there that only set the PSR_ERROR_STATUS. So here refactoring the code a bit to make more easy to read what was state above as more checks will be added to this function. v2: returning a int instead of a bool in psr_get_status_and_error_status() Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by:

The "err" label is not really "err", but rather "out" since the return path is shared between error condition and normal path. This broke when commit 03cea610 ("drm/i915/dsb: fix extra warning on error path handling") added a "dsb->cmd_buf = NULL;" there, making DSB to stop working since now all writes would pass-through via mmio. Remove the set to NULL since it's actually not needed: we only set it if all steps are successful. While at it, rename the label so this confusion doesn't happen again.

The bspec tells us 'Program SHPD_FILTER_CNT with the "500 microseconds adjusted" value before enabling hotplug detection' on CNP+. We haven't been touching this register at all thus far, but we should probably follow the bspec's guidance. The register also exists on LPT and SPT, but there isn't any specific guidance I can find on how we should be programming it there so let's leave it be for now.

When looking at SDEISR to determine the connection status of combo outputs, we should use the phy index rather than the port index. Although they're usually the same thing, EHL's DDI-D (port D) is attached to PHY-A and SDEISR doesn't even have bits for a "D" output. It's also possible that future platforms may map DDIs (the internal display engine programming units) to PHYs (the output handling on the IO side) in ways where port!=phy, so let's look at the PHY index by default. v2: Rename to intel_combo_phy_connected.
