The drivers are free to use the + * resource allocator from the linux core if it suits them, the upside of drm_mm + * is that it's in the DRM core. Which means that it's easier to extend for + * some of the crazier special purpose needs of gpus. + * + * The main data struct is &drm_mm, allocations are tracked in &drm_mm_node. + * Drivers are free to embed either of them into their own suitable + * datastructures. drm_mm itself will not do any allocations of its own, so if + * drivers choose not to embed nodes they need to still allocate them + * themselves. + * + * The range allocator also supports reservation of preallocated blocks. This is + * useful for taking over initial mode setting configurations from the firmware, + * where an object needs to be created which exactly matches the firmware's + * scanout target. As long as the range is still free it can be inserted anytime + * after the allocator is initialized, which helps with avoiding looped + * depencies in the driver load sequence. + * + * drm_mm maintains a stack of most recently freed holes, which of all + * simplistic datastructures seems to be a fairly decent approach to clustering + * allocations and avoiding too much fragmentation. This means free space + * searches are O(num_holes).

Further more every &drm_mm_node has a color value (which is just an + * opaqua unsigned long) which in conjunction with a driver callback can be used + * to implement sophisticated placement restrictions. The i915 DRM driver uses + * this to implement guard pages between incompatible caching domains in the + * graphics TT. + * + * Two behaviors are supported for searching and allocating: bottom-up and top-down. + * The default is bottom-up.

Unfortunately, some + * generations of the hardware will noop these commands in "unsecure" batches + * (which includes all userspace batches submitted via i915) even though the + * commands may be safe and represent the intended programming model of the + * device. + * + * The software command parser is similar in operation to the command parsing + * done in hardware for unsecure batches. However, the software parser allows + * some operations that would be noop'd by hardware, if the parser determines + * the operation is safe, and submits the batch as "secure" to prevent hardware + * parsing. + * + * Threats: + * At a high level, the hardware (and software) checks attempt to prevent + * granting userspace undue privileges. There are three categories of privilege. + * + * First, commands which are explicitly defined as privileged or which should + * only be used by the kernel driver. The parser generally rejects such + * commands, though it may allow some from the drm master process. + * + * Second, commands which access registers. To support correct/enhanced + * userspace functionality, particularly certain OpenGL extensions, the parser + * provides a whitelist of registers which userspace may safely access (for both + * normal and drm master processes). + * + * Third, commands which access privileged memory (i.e. GGTT, HWS page, etc). + * The parser always rejects such commands. + * + * The majority of the problematic commands fall in the MI_* range, with only a + * few specific commands on each ring (e.g. PIPE_CONTROL and MI_FLUSH_DW). + * + * Implementation: + * Each ring maintains tables of commands and registers which the parser uses in + * scanning batch buffers submitted to that ring. + * + * Since the set of commands that the parser must check for is significantly + * smaller than the number of commands supported, the parser tables contain only + * those commands required by the parser. This generally works because command + * opcode ranges have standard command length encodings. So for commands that + * the parser does not need to check, it can easily skip them. This is + * implementated via a per-ring length decoding vfunc. + * + * Unfortunately, there are a number of commands that do not follow the standard + * length encoding for their opcode range, primarily amongst the MI_* commands. + * To handle this, the parser provides a way to define explicit "skip" entries + * in the per-ring command tables. + * + * Other command table entries map fairly directly to high level categories + * mentioned above: rejected, master-only, register whitelist. The parser + * implements a number of checks, including the privileged memory checks, via a + * general bitmasking mechanism. + */ + +static u32 gen7_render_get_cmd_length_mask(u32 cmd_header) +{ + u32 client = (cmd_header & INSTR_CLIENT_MASK) >> INSTR_CLIENT_SHIFT; + u32 subclient = + (cmd_header & INSTR_SUBCLIENT_MASK) >> INSTR_SUBCLIENT_SHIFT; + + if (client == INSTR_MI_CLIENT) + return 0x3F; + else if (client == INSTR_RC_CLIENT) { + if (subclient == INSTR_MEDIA_SUBCLIENT) + return 0xFFFF; + else + return 0xFF; + } + + DRM_DEBUG_DRIVER("CMD: Abnormal rcs cmd length! 0x%08X\n", cmd_header); + return 0; +} + +static u32 gen7_bsd_get_cmd_length_mask(u32 cmd_header) +{ + u32 client = (cmd_header & INSTR_CLIENT_MASK) >> INSTR_CLIENT_SHIFT; + u32 subclient = + (cmd_header & INSTR_SUBCLIENT_MASK) >> INSTR_SUBCLIENT_SHIFT; + + if (client == INSTR_MI_CLIENT) + return 0x3F; + else if (client == INSTR_RC_CLIENT) { + if (subclient == INSTR_MEDIA_SUBCLIENT) + return 0xFFF; + else + return 0xFF; + } + + DRM_DEBUG_DRIVER("CMD: Abnormal bsd cmd length! 0x%08X\n", cmd_header); + return 0; +} + +static u32 gen7_blt_get_cmd_length_mask(u32 cmd_header) +{ + u32 client = (cmd_header & INSTR_CLIENT_MASK) >> INSTR_CLIENT_SHIFT; + + if (client == INSTR_MI_CLIENT) + return 0x3F; + else if (client == INSTR_BC_CLIENT) + return 0xFF; + + DRM_DEBUG_DRIVER("CMD: Abnormal blt cmd length! 0x%08X\n", cmd_header); + return 0; +} + +static void validate_cmds_sorted(struct intel_ring_buffer *ring) +{ + int i; + + if (!ring->cmd_tables || ring->cmd_table_count == 0) + return; + + for (i = 0; i < ring->cmd_table_count; i++) { + const struct drm_i915_cmd_table *table = &ring->cmd_tables[i]; + u32 previous = 0; + int j; + + for (j = 0; j < table->count; j++) { + const struct drm_i915_cmd_descriptor *desc = + &table->table[i]; + u32 curr = desc->cmd.value & desc->cmd.mask; + + if (curr < previous) + DRM_ERROR("CMD: table not sorted ring=%d table=%d entry=%d cmd=0x%08X prev=0x%08X\n", + ring->id, i, j, curr, previous); + + previous = curr; + } + } +} + +static void check_sorted(int ring_id, const u32 *reg_table, int reg_count) +{ + int i; + u32 previous = 0; + + for (i = 0; i < reg_count; i++) { + u32 curr = reg_table[i]; + + if (curr < previous) + DRM_ERROR("CMD: table not sorted ring=%d entry=%d reg=0x%08X prev=0x%08X\n", + ring_id, i, curr, previous); + + previous = curr; + } +} + +static void validate_regs_sorted(struct intel_ring_buffer *ring) +{ + check_sorted(ring->id, ring->reg_table, ring->reg_count); + check_sorted(ring->id, ring->master_reg_table, ring->master_reg_count); +} + +/** + * i915_cmd_parser_init_ring() - set cmd parser related fields for a ringbuffer + * @ring: the ringbuffer to initialize + * + * Optionally initializes fields related to batch buffer command parsing in the + * struct intel_ring_buffer based on whether the platform requires software + * command parsing. + */ +void i915_cmd_parser_init_ring(struct intel_ring_buffer *ring) +{ + if (!IS_GEN7(ring->dev)) + return; + + switch (ring->id) { + case RCS: + ring->get_cmd_length_mask = gen7_render_get_cmd_length_mask; + break; + case VCS: + ring->get_cmd_length_mask = gen7_bsd_get_cmd_length_mask; + break; + case BCS: + ring->get_cmd_length_mask = gen7_blt_get_cmd_length_mask; + break; + case VECS: + /* VECS can use the same length_mask function as VCS */ + ring->get_cmd_length_mask = gen7_bsd_get_cmd_length_mask; + break; + default: + DRM_ERROR("CMD: cmd_parser_init with unknown ring: %d\n", + ring->id); + BUG(); + } + + validate_cmds_sorted(ring); + validate_regs_sorted(ring); +} + +static const struct drm_i915_cmd_descriptor* +find_cmd_in_table(const struct drm_i915_cmd_table *table, + u32 cmd_header) +{ + int i; + + for (i = 0; i < table->count; i++) { + const struct drm_i915_cmd_descriptor *desc = &table->table[i]; + u32 masked_cmd = desc->cmd.mask & cmd_header; + u32 masked_value = desc->cmd.value & desc->cmd.mask; + + if (masked_cmd == masked_value) + return desc; + } + + return NULL; +} + +/* + * Returns a pointer to a descriptor for the command specified by cmd_header. + * + * The caller must supply space for a default descriptor via the default_desc + * parameter.
