Additional information supplied is ROW, 45 * BANK, SUBBANK, SLICE of the affected cacheline. Userspace should keep 46 * track of these events and if a specific cache-line seems to have a 47 * persistent error remap it with the l3 remapping tool supplied in 48 * intel-gpu-tools. The value supplied with the event is always 1. 49 * 50 * I915_ERROR_UEVENT - Generated upon error detection, currently only via 51 * hangcheck. The error detection event is a good indicator of when things 52 * began to go badly. The value supplied with the event is a 1 upon error 53 * detection, and a 0 upon reset completion, signifying no more error 54 * exists. NOTE: Disabling hangcheck or reset via module parameter will 55 * cause the related events to not be seen. 56 * 57 * I915_RESET_UEVENT - Event is generated just before an attempt to reset the 58 * the GPU. The value supplied with the event is always 1. NOTE: Disable 59 * reset via module parameter will cause this event to not be seen. 60 */ 61#define I915_L3_PARITY_UEVENT "L3_PARITY_ERROR" 62#define I915_ERROR_UEVENT "ERROR" 63#define I915_RESET_UEVENT "RESET" 64 65/* Each region is a minimum of 16k, and there are at most 255 of them. 66 */ 67#define I915_NR_TEX_REGIONS 255 /* table size 2k - maximum due to use 68 * of chars for next/prev indices */ 69#define I915_LOG_MIN_TEX_REGION_SIZE 14 70 71typedef struct _drm_i915_init { 72 enum { 73 I915_INIT_DMA = 0x01, 74 I915_CLEANUP_DMA = 0x02, 75 I915_RESUME_DMA = 0x03 76 } func; 77 unsigned int mmio_offset; 78 int sarea_priv_offset; 79 unsigned int ring_start; 80 unsigned int ring_end; 81 unsigned int ring_size; 82 unsigned int front_offset; 83 unsigned int back_offset; 84 unsigned int depth_offset; 85 unsigned int w; 86 unsigned int h; 87 unsigned int pitch; 88 unsigned int pitch_bits; 89 unsigned int back_pitch; 90 unsigned int depth_pitch; 91 unsigned int cpp; 92 unsigned int chipset; 93} drm_i915_init_t; 94 95typedef struct _drm_i915_sarea { 96 struct drm_tex_region texList[I915_NR_TEX_REGIONS + 1]; 97 int last_upload; /* last time texture was uploaded */ 98 int last_enqueue; /* last time a buffer was enqueued */ 99 int last_dispatch; /* age of the most recently dispatched buffer */ 100 int ctxOwner; /* last context to upload state */ 101 int texAge; 102 int pf_enabled; /* is pageflipping allowed? */ 103 int pf_active; 104 int pf_current_page; /* which buffer is being displayed? */ 105 int perf_boxes; /* performance boxes to be displayed */ 106 int width, height; /* screen size in pixels */ 107 108 drm_handle_t front_handle; 109 int front_offset; 110 int front_size; 111 112 drm_handle_t back_handle; 113 int back_offset; 114 int back_size; 115 116 drm_handle_t depth_handle; 117 int depth_offset; 118 int depth_size; 119 120 drm_handle_t tex_handle; 121 int tex_offset; 122 int tex_size; 123 int log_tex_granularity; 124 int pitch; 125 int rotation; /* 0, 90, 180 or 270 */ 126 int rotated_offset; 127 int rotated_size; 128 int rotated_pitch; 129 int virtualX, virtualY; 130 131 unsigned int front_tiled; 132 unsigned int back_tiled; 133 unsigned int depth_tiled; 134 unsigned int rotated_tiled; 135 unsigned int rotated2_tiled; 136 137 int pipeA_x; 138 int pipeA_y; 139 int pipeA_w; 140 int pipeA_h; 141 int pipeB_x; 142 int pipeB_y; 143 int pipeB_w; 144 int pipeB_h; 145 146 /* fill out some space for old userspace triple buffer */ 147 drm_handle_t unused_handle; 148 __u32 unused1, unused2, unused3; 149 150 /* buffer object handles for static buffers.
