2017-11-14drm/i915/glk: Refactor handling of PLANE_COLOR_CTL for GLK+James Ausmus4-25/+76
Since GLK, some plane configuration settings have moved to the PLANE_COLOR_CTL register. Refactor handling of the register to work like PLANE_CTL. This also allows us to fix the set/read of the plane Alpha Mode for GLK+. v2: Adjust ordering of platform checks to be newest->oldest, drop redundant comment about alpha blending. (Ville) v3: Move Alpha Mode bits out of skl_plane_ctl_format into skl_plane_ctl_alpha, and drop glk_plane_ctl_format, drop initialization of state->color_ctl on platforms that don't use it, and drop color_ctl local var.

2017-11-14drm/i915: Introduce GEM proxyTina Zhang3-4/+47
GEM proxy is a kind of GEM, whose backing physical memory is pinned and produced by guest VM and is used by host as read only. With GEM proxy, host is able to access guest physical memory through GEM object interface. As GEM proxy is such a special kind of GEM, a new flag I915_GEM_OBJECT_IS_PROXY is introduced to ban host from changing the backing storage of GEM proxy. v3: - update "Reviewed-by". (Joonas) v2: - return -ENXIO when pin and map pages of GEM proxy to kernel space. (Chris) Here are the histories of this patch in "Dma-buf support for Gvt-g" patch-set: v14: - return -ENXIO when gem proxy object is banned by ioctl. (Chris) (Daniel) v13: - add comments to GEM proxy. (Chris) - don't ban GEM proxy in i915_gem_sw_finish_ioctl. (Chris) - check GEM proxy bar after finishing i915_gem_object_wait.

Pull power management updates from Rafael Wysocki: "There are no real big ticket items here this time. The most noticeable change is probably the relocation of the OPP (Operating Performance Points) framework to its own directory under drivers/ as it has grown big enough for that. Also Viresh is now going to maintain it and send pull requests for it to me, so you will see this change in the git history going forward (but still not right now). Another noticeable set of changes is the modifications of the PM core, the PCI subsystem and the ACPI PM domain to allow of more integration between system-wide suspend/resume and runtime PM. For now it's just a way to avoid resuming devices from runtime suspend unnecessarily during system suspend (if the driver sets a flag to indicate its readiness for that) and in the works is an analogous mechanism to allow devices to stay suspended after system resume. In addition to that, we have some changes related to supporting frequency-invariant CPU utilization metrics in the scheduler and in the schedutil cpufreq governor on ARM and changes to add support for device performance states to the generic power domains (genpd) framework. The rest is mostly fixes and cleanups of various sorts. Specifics: - Relocate the OPP (Operating Performance Points) framework to its own directory under drivers/ and add support for power domain performance states to it (Viresh Kumar). - Modify the PM core, the PCI bus type and the ACPI PM domain to support power management driver flags allowing device drivers to specify their capabilities and preferences regarding the handling of devices with enabled runtime PM during system suspend/resume and clean up that code somewhat (Rafael Wysocki, Ulf Hansson). - Add frequency-invariant accounting support to the task scheduler on ARM and ARM64 (Dietmar Eggemann). - Fix PM QoS device resume latency framework to prevent "no restriction" requests from overriding requests with specific requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP device PM QoS flag (Rafael Wysocki). - Drop legacy class suspend/resume operations from the PM core and drop legacy bus type suspend and resume callbacks from ARM/locomo (Rafael Wysocki). - Add min/max frequency support to devfreq and clean it up somewhat (Chanwoo Choi). - Rework wakeup support in the generic power domains (genpd) framework and update some of its users accordingly (Geert Uytterhoeven). - Convert timers in the PM core to use timer_setup() (Kees Cook). - Add support for exposing the SLP_S0 (Low Power S0 Idle) residency counter based on the LPIT ACPI table on Intel platforms (Srinivas Pandruvada). - Add per-CPU PM QoS resume latency support to the ladder cpuidle governor (Ramesh Thomas). - Fix a deadlock between the wakeup notify handler and the notifier removal in the ACPI core (Ville Syrjälä). - Fix a cpufreq schedutil governor issue causing it to use stale cached frequency values sometimes (Viresh Kumar). - Fix an issue in the system suspend core support code causing wakeup events detection to fail in some cases (Rajat Jain). - Fix the generic power domains (genpd) framework to prevent the PM core from using the direct-complete optimization with it as that is guaranteed to fail (Ulf Hansson). - Fix a minor issue in the cpuidle core and clean it up a bit (Gaurav Jindal, Nicholas Piggin). - Fix and clean up the intel_idle and ARM cpuidle drivers (Jason Baron, Len Brown, Leo Yan). - Fix a couple of minor issues in the OPP framework and clean it up (Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan). - Fix and clean up some cpufreq drivers and fix a minor issue in the cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio Estevam, Gautham Shenoy, Gustavo Silva, Marek Szyprowski, Masahiro Yamada, Robert Jarzmik, Zumeng Chen). - Fix minor issues in the system suspend and hibernation core, in power management documentation and in the AVS (Adaptive Voltage Scaling) framework (Helge Deller, Himanshu Jha, Joe Perches, Rafael Wysocki). - Fix some issues in the cpupower utility and document that Shuah Khan is going to maintain it going forward (Prarit Bhargava, Shuah Khan)" * tag 'pm-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (88 commits) tools/power/cpupower: add libcpupower.so.0.0.1 to .gitignore tools/power/cpupower: Add 64 bit library detection intel_idle: Graceful probe failure when MWAIT is disabled cpufreq: schedutil: Reset cached_raw_freq when not in sync with next_freq freezer: Fix typo in freezable_schedule_timeout() comment PM / s2idle: Clear the events_check_enabled flag cpufreq: stats: Handle the case when trans_table goes beyond PAGE_SIZE cpufreq: arm_big_little: make cpufreq_arm_bL_ops structures const cpufreq: arm_big_little: make function arguments and structure pointer const cpuidle: Avoid assignment in if () argument cpuidle: Clean up cpuidle_enable_device() error handling a bit ACPI / PM: Fix acpi_pm_notifier_lock vs flush_workqueue() deadlock PM / Domains: Fix genpd to deal with drivers returning 1 from ->prepare() cpuidle: ladder: Add per CPU PM QoS resume latency support PM / QoS: Fix device resume latency framework PM / domains: Rework governor code to be more consistent PM / Domains: Remove gpd_dev_ops.active_wakeup() callback soc: rockchip: power-domain: Use GENPD_FLAG_ACTIVE_WAKEUP soc: mediatek: Use GENPD_FLAG_ACTIVE_WAKEUP ARM: shmobile: pm-rmobile: Use GENPD_FLAG_ACTIVE_WAKEUP ...

Pull timer updates from Thomas Gleixner: "Yet another big pile of changes: - More year 2038 work from Arnd slowly reaching the point where we need to think about the syscalls themself. - A new timer function which allows to conditionally (re)arm a timer only when it's either not running or the new expiry time is sooner than the armed expiry time. This allows to use a single timer for multiple timeout requirements w/o caring about the first expiry time at the call site. - A new NMI safe accessor to clock real time for the printk timestamp work. Can be used by tracing, perf as well if required. - A large number of timer setup conversions from Kees which got collected here because either maintainers requested so or they simply got ignored. As Kees pointed out already there are a few trivial merge conflicts and some redundant commits which was unavoidable due to the size of this conversion effort. - Avoid a redundant iteration in the timer wheel softirq processing. - Provide a mechanism to treat RTC implementations depending on their hardware properties, i.e. don't inflict the write at the 0.5 seconds boundary which originates from the PC CMOS RTC to all RTCs.

2017-11-13drm/i915: There is only one fault register from GEN8 onwardsMichel Thierry3-18/+49
Until Haswell/Baytrail, the hardware used to have a per engine fault register (e.g. 0x4094 - render fault register, 0x4194 - media fault register and so on). But since Broadwell, all these registers were combined into a singe one and the engine id stored in bits 14:12. Not only we should not been reading (and writing to) registers that do not exist, in platforms with VCS2 (SKL), the address that would belong this engine (0x4494, VCS2_HW = 4) is already assigned to other register. v2: use less controversial function names (Chris). v3: make non-exported functions static, remove now obsolete check for engine presence before posting_read (Chris).

This is particularly useful for performance monitoring where much of the normalization work is done using those timestamps (this include pipeline statistics in both GL & Vulkan as well as OA reports). v2: Use variables for 24MHz/19.2MHz values (Ewelina) Renamed function & coding style (Sagar) v3: Fix frequency read on Broadwell (Sagar) Fix missing divide by 4 on <= gen4 (Sagar) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Tested-by: Rafael Antognolli <rafael.antognolli@intel.com> Reviewed-by: Sagar Arun Kamble <sagar.a.kamble@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171110190845.32574-7-lionel.g.landwerlin@intel.com

Also, change the argument name in the bit_wait*() function declarations to reflect the fact that it's the mode and not the bit number.

2017-11-12drm/i915: Remove redundant intel_autoenable_gt_powersave()Chris Wilson5-86/+24
Now that we always execute a context switch upon module load, there is no need to queue a delayed task for doing so. The purpose of the delayed task is to enable GT powersaving, for which we need the HW state to be valid (i.e. having loaded a context and initialised basic state). We used to defer this operation as historically it was slow (due to slow register polling, fixed with commit 1758b90e38f5 ("drm/i915: Use a hybrid scheme for fast register waits")) but now we have a requirement to save the default HW state. v2: Load the kernel context (to provide the power context) upon resume.

We no longer use intel_crtc->wm.active for watermarks any more, which was incorrect. But this uncovered a bug in sanitize_watermarks(), which meant that we wrote the correct watermarks, but the next update would still use the wrong hw watermarks for calculating. This caused all further updates to fail with -EINVAL and the log would reveal an error like the one below: [ 10.043902] [drm:ilk_validate_wm_level.part.8 [i915]] Sprite WM0 too large 56 (max 0) [ 10.043960] [drm:ilk_validate_pipe_wm [i915]] LP0 watermark invalid [ 10.044030] [drm:intel_crtc_atomic_check [i915]] No valid intermediate pipe watermarks are possible Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Fixes: b6b178a77210 ("drm/i915: Calculate ironlake intermediate watermarks correctly, v2.")
