Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main git pull for the drm,
I pretty much froze major pulls at -rc5/6 time, and haven't had much
fallout, so will probably continue doing that.
Lots of changes all over, big internal header cleanup to make it clear
drm features are legacy things and what are things that modern KMS
drivers should be using. Also big move to use the new generic fences
in all the TTM drivers.
core:
atomic prep work,
vblank rework changes, allows immediate vblank disables
major header reworking and cleanups to better delinate legacy
interfaces from what KMS drivers should be using.
cursor planes locking fixes
ttm:
move to generic fences (affects all TTM drivers)
ppc64 caching fixes
radeon:
userptr support,
uvd for old asics,
reset rework for fence changes
better buffer placement changes,
dpm feature enablement
hdmi audio support fixes
intel:
Cherryview work,
180 degree rotation,
skylake prep work,
execlist command submission
full ppgtt prep work
cursor improvements
edid caching,
vdd handling improvements
nouveau:
fence reworking
kepler memory clock work
gt21x clock work
fan control improvements
hdmi infoframe fixes
DP audio
ast:
ppc64 fixes
caching fix
rcar:
rcar-du DT support
ipuv3:
prep work for capture support
msm:
LVDS support for mdp4, new panel, gpu refactoring
exynos:
exynos3250 SoC support, drop bad mmap interface,
mipi dsi changes, and component match support"

This is + * where the name "Logical Rings" starts to make sense: by virtualizing the + * rings, the engine cs shifts to a new "ring buffer" with every context + * switch. When you want to submit a workload to the GPU you: A) choose your + * context, B) find its appropriate virtualized ring, C) write commands to it + * and then, finally, D) tell the GPU to switch to that context. + * + * Instead of the legacy MI_SET_CONTEXT, the way you tell the GPU to switch + * to a contexts is via a context execution list, ergo "Execlists". + * + * LRC implementation: + * Regarding the creation of contexts, we have: + * + * - One global default context. + * - One local default context for each opened fd. + * - One local extra context for each context create ioctl call. + * + * Now that ringbuffers belong per-context (and not per-engine, like before) + * and that contexts are uniquely tied to a given engine (and not reusable, + * like before) we need: + * + * - One ringbuffer per-engine inside each context. + * - One backing object per-engine inside each context. + * + * The global default context starts its life with these new objects fully + * allocated and populated. The local default context for each opened fd is + * more complex, because we don't know at creation time which engine is going + * to use them. To handle this, we have implemented a deferred creation of LR + * contexts: + * + * The local context starts its life as a hollow or blank holder, that only + * gets populated for a given engine once we receive an execbuffer. If later + * on we receive another execbuffer ioctl for the same context but a different + * engine, we allocate/populate a new ringbuffer and context backing object and + * so on. + * + * Finally, regarding local contexts created using the ioctl call: as they are + * only allowed with the render ring, we can allocate & populate them right + * away (no need to defer anything, at least for now). + * + * Execlists implementation: + * Execlists are the new method by which, on gen8+ hardware, workloads are + * submitted for execution (as opposed to the legacy, ringbuffer-based, method). + * This method works as follows: + * + * When a request is committed, its commands (the BB start and any leading or + * trailing commands, like the seqno breadcrumbs) are placed in the ringbuffer + * for the appropriate context. The tail pointer in the hardware context is not + * updated at this time, but instead, kept by the driver in the ringbuffer + * structure. A structure representing this request is added to a request queue + * for the appropriate engine: this structure contains a copy of the context's + * tail after the request was written to the ring buffer and a pointer to the + * context itself. + * + * If the engine's request queue was empty before the request was added, the + * queue is processed immediately. Otherwise the queue will be processed during + * a context switch interrupt. In any case, elements on the queue will get sent + * (in pairs) to the GPU's ExecLists Submit Port (ELSP, for short) with a + * globally unique 20-bits submission ID. + * + * When execution of a request completes, the GPU updates the context status + * buffer with a context complete event and generates a context switch interrupt. + * During the interrupt handling, the driver examines the events in the buffer: + * for each context complete event, if the announced ID matches that on the head + * of the request queue, then that request is retired and removed from the queue. + * + * After processing, if any requests were retired and the queue is not empty + * then a new execution list can be submitted. The two requests at the front of + * the queue are next to be submitted but since a context may not occur twice in + * an execution list, if subsequent requests have the same ID as the first then + * the two requests must be combined. This is done simply by discarding requests + * at the head of the queue until either only one requests is left (in which case + * we use a NULL second context) or the first two requests have unique IDs. + * + * By always executing the first two requests in the queue the driver ensures + * that the GPU is kept as busy as possible. In the case where a single context + * completes but a second context is still executing, the request for this second + * context will be at the head of the queue when we remove the first one. This + * request will then be resubmitted along with a new request for a different context, + * which will cause the hardware to continue executing the second request and queue + * the new request (the GPU detects the condition of a context getting preempted + * with the same context and optimizes the context switch flow by not doing + * preemption, but just sampling the new tail pointer). + * + */ + +#include <drm/drmP.h> +#include <drm/i915_drm.h> +#include "i915_drv.h" + +#define GEN8_LR_CONTEXT_RENDER_SIZE (20 * PAGE_SIZE) +#define GEN8_LR_CONTEXT_OTHER_SIZE (2 * PAGE_SIZE) + +#define GEN8_LR_CONTEXT_ALIGN 4096 + +#define RING_EXECLIST_QFULL (1 << 0x2) +#define RING_EXECLIST1_VALID (1 << 0x3) +#define RING_EXECLIST0_VALID (1 << 0x4) +#define RING_EXECLIST_ACTIVE_STATUS (3 << 0xE) +#define RING_EXECLIST1_ACTIVE (1 << 0x11) +#define RING_EXECLIST0_ACTIVE (1 << 0x12) + +#define GEN8_CTX_STATUS_IDLE_ACTIVE (1 << 0) +#define GEN8_CTX_STATUS_PREEMPTED (1 << 1) +#define GEN8_CTX_STATUS_ELEMENT_SWITCH (1 << 2) +#define GEN8_CTX_STATUS_ACTIVE_IDLE (1 << 3) +#define GEN8_CTX_STATUS_COMPLETE (1 << 4) +#define GEN8_CTX_STATUS_LITE_RESTORE (1 << 15) + +#define CTX_LRI_HEADER_0 0x01 +#define CTX_CONTEXT_CONTROL 0x02 +#define CTX_RING_HEAD 0x04 +#define CTX_RING_TAIL 0x06 +#define CTX_RING_BUFFER_START 0x08 +#define CTX_RING_BUFFER_CONTROL 0x0a +#define CTX_BB_HEAD_U 0x0c +#define CTX_BB_HEAD_L 0x0e +#define CTX_BB_STATE 0x10 +#define CTX_SECOND_BB_HEAD_U 0x12 +#define CTX_SECOND_BB_HEAD_L 0x14 +#define CTX_SECOND_BB_STATE 0x16 +#define CTX_BB_PER_CTX_PTR 0x18 +#define CTX_RCS_INDIRECT_CTX 0x1a +#define CTX_RCS_INDIRECT_CTX_OFFSET 0x1c +#define CTX_LRI_HEADER_1 0x21 +#define CTX_CTX_TIMESTAMP 0x22 +#define CTX_PDP3_UDW 0x24 +#define CTX_PDP3_LDW 0x26 +#define CTX_PDP2_UDW 0x28 +#define CTX_PDP2_LDW 0x2a +#define CTX_PDP1_UDW 0x2c +#define CTX_PDP1_LDW 0x2e +#define CTX_PDP0_UDW 0x30 +#define CTX_PDP0_LDW 0x32 +#define CTX_LRI_HEADER_2 0x41 +#define CTX_R_PWR_CLK_STATE 0x42 +#define CTX_GPGPU_CSR_BASE_ADDRESS 0x44 + +#define GEN8_CTX_VALID (1<<0) +#define GEN8_CTX_FORCE_PD_RESTORE (1<<1) +#define GEN8_CTX_FORCE_RESTORE (1<<2) +#define GEN8_CTX_L3LLC_COHERENT (1<<5) +#define GEN8_CTX_PRIVILEGE (1<<8) +enum { + ADVANCED_CONTEXT = 0, + LEGACY_CONTEXT, + ADVANCED_AD_CONTEXT, + LEGACY_64B_CONTEXT +}; +#define GEN8_CTX_MODE_SHIFT 3 +enum { + FAULT_AND_HANG = 0, + FAULT_AND_HALT, /* Debug only */ + FAULT_AND_STREAM, + FAULT_AND_CONTINUE /* Unsupported */ +}; +#define GEN8_CTX_ID_SHIFT 32 + +/** + * intel_sanitize_enable_execlists() - sanitize i915.enable_execlists + * @dev: DRM device. + * @enable_execlists: value of i915.enable_execlists module parameter. + * + * Only certain platforms support Execlists (the prerequisites being + * support for Logical Ring Contexts and Aliasing PPGTT or better), + * and only when enabled via module parameter. + * + * Return: 1 if Execlists is supported and has to be enabled. + */ +int intel_sanitize_enable_execlists(struct drm_device *dev, int enable_execlists) +{ + WARN_ON(i915.enable_ppgtt == -1); + + if (enable_execlists == 0) + return 0; + + if (HAS_LOGICAL_RING_CONTEXTS(dev) && USES_PPGTT(dev) && + i915.use_mmio_flip >= 0) + return 1; + + return 0; +} + +/** + * intel_execlists_ctx_id() - get the Execlists Context ID + * @ctx_obj: Logical Ring Context backing object. + * + * Do not confuse with ctx->id!
