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!
