2019-04-03drm/i915: Skip modeset for cdclk changes if possibleVille Syrjälä
If we have only a single active pipe and the cdclk change only requires the cd2x divider to be updated bxt+ can do the update with forcing a full modeset on the pipe. Try to hook that up. v2: - Wait for vblank after an optimized CDCLK change. - Avoid optimization if the pipe needs a modeset (or was disabled). - Split CDCLK change to a pre/post plane update step. v3: - Use correct version of CDCLK state as old state. (Ville) - Remove unused intel_cdclk_can_skip_modeset() v4: - For consistency call intel_set_cdclk_post_plane_update() only during modesets (and not fastsets). v5: - Remove the logic to update the CD2X divider on-the-fly on ICL, since only a divider of 1 is supported there. Clint also noticed that the pipe select bits in CDCLK_CTL are oddly defined on ICL, it's not clear yet whether that's only an error in the specification.

2019-04-01drm/i915: Introduce concept of a sub-platformTvrtko Ursulin
Concept of a sub-platform already exist in our code (like ULX and ULT platform variants and similar),implemented via the macros which check a list of device ids to determine a match. With this patch we consolidate device ids checking into a single function called during early driver load. A few low bits in the platform mask are reserved for sub-platform identification and defined as a per-platform namespace. At the same time it future proofs the platform_mask handling by preparing the code for easy extending, and tidies the very verbose WARN strings generated when IS_PLATFORM macros are embedded into a WARN type statements. v2: Fixed IS_SUBPLATFORM. Updated commit msg. v3: Chris was right, there is an ordering problem. v4: * Catch-up with new sub-platforms. * Rebase for RUNTIME_INFO. * Drop subplatform mask union tricks and convert platform_mask to an array for extensibility. v5: * Fix subplatform check. * Protect against forgetting to expand subplatform bits. * Remove platform enum tallying. * Add subplatform to error state. (Chris) * Drop macros and just use static inlines. * Remove redundant IRONLAKE_M. (Ville) v6: * Split out Ironlake change. * Optimize subplatform check. * Use __always_inline. (Lucas) * Add platform_mask comment. (Paulo) * Pass stored runtime info in error capture.

Iterate over child devices instead of ports in parse_ddi_ports() to initialize ddi_port_info. We'll eventually need to decide some stuff based on the child device order, which may be different from the port order. As a bonus, this allows better abstractions for e.g. dvo port mapping. There's a subtle change in the DDC pin and AUX channel sanitization as we change the order. Otherwise, this should not change behaviour.

2019-03-25drm/i915: Disable C3 when enabling vblank interrupts on i945gmVille Syrjälä
The AGPBUSY thing doesn't work on i945gm anymore. This means the gmch is incapable of waking the CPU from C3 when an interrupt is generated. The interrupts just get postponed indefinitely until something wakes up the CPU. This is rather annoying for vblank interrupts as we are unable to maintain a steady framerate unless the machine is sufficiently loaded to stay out of C3. To combat this let's use pm_qos to prevent C3 whenever vblank interrupts are enabled. To maintain reasonable amount of powersaving we will attempt to limit this to C3 only while leaving C1 and C2 enabled. v2: Use READ_ONCE() (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30364 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190322180804.3300-1-ville.syrjala@linux.intel.com Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

2019-03-21drm/i915: Flush pages on acquisitionChris Wilson
When we return pages to the system, we ensure that they are marked as being in the CPU domain since any external access is uncontrolled and we must assume the worst. This means that we need to always flush the pages on acquisition if we need to use them on the GPU, and from the beginning have used set-domain. Set-domain is overkill for the purpose as it is a general synchronisation barrier, but our intent is to only flush the pages being swapped in. If we move that flush into the pages acquisition phase, we know then that when we have obj->mm.pages, they are coherent with the GPU and need only maintain that status without resorting to heavy handed use of set-domain. The principle knock-on effect for userspace is through mmap-gtt pagefaulting. Our uAPI has always implied that the GTT mmap was async (especially as when any pagefault occurs is unpredicatable to userspace) and so userspace had to apply explicit domain control itself (set-domain). However, swapping is transparent to the kernel, and so on first fault we need to acquire the pages and make them coherent for access through the GTT. Our use of set-domain here leaks into the uABI that the first pagefault was synchronous. This is unintentional and baring a few igt should be unoticed, nevertheless we bump the uABI version for mmap-gtt to reflect the change in behaviour. Another implication of the change is that gem_create() is presumed to create an object that is coherent with the CPU and is in the CPU write domain, so a set-domain(CPU) following a gem_create() would be a minor operation that merely checked whether we could allocate all pages for the object. On applying this change, a set-domain(CPU) causes a clflush as we acquire the pages. This will have a small impact on mesa as we move the clflush here on !llc from execbuf time to create, but that should have minimal performance impact as the same clflush exists but is now done early and because of the clflush issue, userspace recycles bo and so should resist allocating fresh objects. Internally, the presumption that objects are created in the CPU write-domain and remain so through writes to obj->mm.mapping is more prevalent than I expected; but easy enough to catch and apply a manual flush. For the future, we should push the page flush from the central set_pages() into the callers so that we can more finely control when it is applied, but for now doing it one location is easier to validate, at the cost of sometimes flushing when there is no need.

2019-03-13drm/i915: Start using comparative INTEL_PCH_TYPERodrigo Vivi
In order to make it easier to bring up new platforms without having to take care about all corner cases that was previously taken care for previous platforms we already use comparative INTEL_GEN statements. Let's start doing the same with PCH. The only caveats are: - less-than comparisons need to be avoided or done with attention and check > PCH_NONE as well. - It is not necessarily a chronological order, but a matter of south display compatibility/inheritance. v2: Rebased on top of Jani's clean-up which removed the need for less-than comparison Cc: Jani Nikula <jani.nikula@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190308214300.25057-3-rodrigo.vivi@intel.com

2019-03-08drm/i915: Reduce presumption of request ordering for barriersChris Wilson
Currently we assume that we know the order in which requests run and so can determine if we need to reissue a switch-to-kernel-context prior to idling. That assumption does not hold for the future, so instead of tracking which barriers have been used, simply determine if we have ever switched away from the kernel context by using the engine and before idling ensure that all engines that have been used since the last idle are synchronously switched back to the kernel context for safety (and else of shrinking memory while idle). v2: Use intel_engine_mask_t and ALL_ENGINES Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190308093657.8640-3-chris@chris-wilson.co.uk
2019-03-08drm/i915: Do a synchronous switch-to-kernel-context on idlingChris Wilson
When the system idles, we switch to the kernel context as a defensive measure (no users are harmed if the kernel context is lost). Currently, we issue a switch to kernel context and then come back later to see if the kernel context is still current and the system is idle. However, if we are no longer privy to the runqueue ordering, then we have to relax our assumptions about the logical state of the GPU and the only way to ensure that the kernel context is currently loaded is by issuing a request to run after all others, and wait for it to complete all while preventing anyone else from issuing their own requests. v2: Pull wedging into switch_to_kernel_context_sync() but only after waiting (though only for the same short delay) for the active context to finish.
