2016-10-14irqchip/jcore: Fix lost per-cpu interruptsRich Felker1-1/+19
The J-Core AIC does not have separate interrupt numbers reserved for cpu-local vs global interrupts. Instead, the driver requesting the irq is expected to know whether its device uses per-cpu interrupts or not. Previously it was assumed that handle_simple_irq could work for both cases, but it intentionally drops interrupts for an irq number that already has a handler running. This resulted in the timer interrupt for one cpu being lost when multiple cpus' timers were set for approximately the same expiration time, leading to stalls. In theory the same could also happen with IPIs. To solve the problem, instead of registering handle_simple_irq as the handler, register a wrapper function which checks whether the irq to be handled was requested as per-cpu or not, and passes it to handle_simple_irq or handle_percpu_irq accordingly.

2016-10-14drm/i915/gtt: Free unused lower-level page tablesMichał Winiarski1-8/+73
Since "Dynamic page table allocations" were introduced, our page tables can grow (being dynamically allocated) with address space range usage. Unfortunately, their lifetime is bound to vm. This is not a huge problem when we're not using softpin - drm_mm is creating an upper bound on used range by causing addresses for our VMAs to eventually be reused. With softpin, long lived contexts can drain the system out of memory even with a single "small" object. For example: bo = bo_alloc(size); while(true) offset += size; exec(bo, offset); Will cause us to create new allocations until all memory in the system is used for tracking GPU pages (even though almost all PTEs in this vm are pointing to scratch). Let's free unused page tables in clear_range to prevent this - if no entries are used, we can safely free it and return this information to the caller (so that higher-level entry is pointing to scratch). v2: Document return value and free semantics (Joonas) v3: No newlines in vars block (Joonas) v4: Drop redundant local 'reduce' variable v5: Handle CI fail with enable_ppgtt=2 Cc: Michel Thierry <michel.thierry@intel.com> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1476360162-24062-3-git-send-email-michal.winiarski@intel.com

Let's use more top-down approach, where each gen8_ppgtt_clear_* function is responsible for clearing the struct passed as an argument and calling relevant clear_range functions on lower-level tables.

2016-10-14drm/i915: Fix mismatched INIT power domain disabling during suspendImre Deak1-2/+2
Currently the display INIT power domain disabling/enabling happens in a mismatched way in the suspend/resume_early hooks respectively. This can leave display power wells incorrectly disabled in the resume hook if the suspend sequence is aborted for some reason resulting in the suspend/resume hooks getting called but the suspend_late/resume_early hooks being skipped. In particular this change fixes "Unclaimed read from register 0x1e1204" on BYT/BSW triggered from i915_drm_resume()-> intel_pps_unlock_regs_wa() when suspending with /sys/power/pm_test set to devices.

2016-10-14drm/i915/gvt: vGPU workload schedulerZhi Wang10-8/+661
This patch introduces the vGPU workload scheduler routines. GVT workload scheduler is responsible for picking and executing GVT workload from current scheduled vGPU. Before the workload is submitted to host i915, the guest execlist context will be shadowed in the host GVT shadow context. the instructions in guest ring buffer will be copied into GVT shadow ring buffer. Then GVT-g workload scheduler will scan the instructions in guest ring buffer and submit it to host i915.

2016-10-14drm/i915/gvt: vGPU workload submissionZhi Wang7-6/+449
This patch introduces the vGPU workload submission logics. Under virtualization environment, guest will submit workload through virtual execlist submit port. The submitted workload load will be wrapped into an gvt workload which will be picked by GVT workload scheduler and executed on host i915 later.
