1=========================== 2 drm/i915 Intel GFX Driver 3=========================== 4 5The drm/i915 driver supports all (with the exception of some very early 6models) integrated GFX chipsets with both Intel display and rendering 7blocks. This excludes a set of SoC platforms with an SGX rendering unit, 8those have basic support through the gma500 drm driver. 9 10Core Driver Infrastructure 11========================== 12 13This section covers core driver infrastructure used by both the display 14and the GEM parts of the driver. 15 16Runtime Power Management 17------------------------ 18 19.. kernel-doc:: drivers/gpu/drm/i915/intel_runtime_pm.c 20 :doc: runtime pm 21 22.. kernel-doc:: drivers/gpu/drm/i915/intel_runtime_pm.c 23 :internal: 24 25.. kernel-doc:: drivers/gpu/drm/i915/intel_uncore.c 26 :internal: 27 28Interrupt Handling 29------------------ 30 31.. kernel-doc:: drivers/gpu/drm/i915/i915_irq.c 32 :doc: interrupt handling 33 34.. kernel-doc:: drivers/gpu/drm/i915/i915_irq.c 35 :functions: intel_irq_init intel_irq_init_hw intel_hpd_init 36 37.. kernel-doc:: drivers/gpu/drm/i915/i915_irq.c 38 :functions: intel_runtime_pm_disable_interrupts 39 40.. kernel-doc:: drivers/gpu/drm/i915/i915_irq.c 41 :functions: intel_runtime_pm_enable_interrupts 42 43Intel GVT-g Guest Support(vGPU) 44------------------------------- 45 46.. kernel-doc:: drivers/gpu/drm/i915/i915_vgpu.c 47 :doc: Intel GVT-g guest support 48 49.. kernel-doc:: drivers/gpu/drm/i915/i915_vgpu.c 50 :internal: 51 52Intel GVT-g Host Support(vGPU device model) 53------------------------------------------- 54 55.. kernel-doc:: drivers/gpu/drm/i915/intel_gvt.c 56 :doc: Intel GVT-g host support 57 58.. kernel-doc:: drivers/gpu/drm/i915/intel_gvt.c 59 :internal: 60 61Display Hardware Handling 62========================= 63 64This section covers everything related to the display hardware including 65the mode setting infrastructure, plane, sprite and cursor handling and 66display, output probing and related topics. 67 68Mode Setting Infrastructure 69--------------------------- 70 71The i915 driver is thus far the only DRM driver which doesn't use the 72common DRM helper code to implement mode setting sequences. Thus it has 73its own tailor-made infrastructure for executing a display configuration 74change. 75 76Frontbuffer Tracking 77-------------------- 78 79.. kernel-doc:: drivers/gpu/drm/i915/intel_frontbuffer.c 80 :doc: frontbuffer tracking 81 82.. kernel-doc:: drivers/gpu/drm/i915/intel_frontbuffer.h 83 :internal: 84 85.. kernel-doc:: drivers/gpu/drm/i915/intel_frontbuffer.c 86 :internal: 87 88.. kernel-doc:: drivers/gpu/drm/i915/i915_gem.c 89 :functions: i915_gem_track_fb 90 91Display FIFO Underrun Reporting 92------------------------------- 93 94.. kernel-doc:: drivers/gpu/drm/i915/intel_fifo_underrun.c 95 :doc: fifo underrun handling 96 97.. kernel-doc:: drivers/gpu/drm/i915/intel_fifo_underrun.c 98 :internal: 99 100Plane Configuration 101------------------- 102 103This section covers plane configuration and composition with the primary 104plane, sprites, cursors and overlays. This includes the infrastructure 105to do atomic vsync'ed updates of all this state and also tightly coupled 106topics like watermark setup and computation, framebuffer compression and 107panel self refresh. 108 109Atomic Plane Helpers 110-------------------- 111 112.. kernel-doc:: drivers/gpu/drm/i915/intel_atomic_plane.c 113 :doc: atomic plane helpers 114 115.. kernel-doc:: drivers/gpu/drm/i915/intel_atomic_plane.c 116 :internal: 117 118Output Probing 119-------------- 120 121This section covers output probing and related infrastructure like the 122hotplug interrupt storm detection and mitigation code. Note that the 123i915 driver still uses most of the common DRM helper code for output 124probing, so those sections fully apply. 125 126Hotplug 127------- 128 129.. kernel-doc:: drivers/gpu/drm/i915/intel_hotplug.c 130 :doc: Hotplug 131 132.. kernel-doc:: drivers/gpu/drm/i915/intel_hotplug.c 133 :internal: 134 135High Definition Audio 136--------------------- 137 138.. kernel-doc:: drivers/gpu/drm/i915/intel_audio.c 139 :doc: High Definition Audio over HDMI and Display Port 140 141.. kernel-doc:: drivers/gpu/drm/i915/intel_audio.c 142 :internal: 143 144.. kernel-doc:: include/drm/i915_component.h 145 :internal: 146 147Panel Self Refresh PSR (PSR/SRD) 148-------------------------------- 149 150.. kernel-doc:: drivers/gpu/drm/i915/intel_psr.c 151 :doc: Panel Self Refresh (PSR/SRD) 152 153.. kernel-doc:: drivers/gpu/drm/i915/intel_psr.c 154 :internal: 155 156Frame Buffer Compression (FBC) 157------------------------------ 158 159.. kernel-doc:: drivers/gpu/drm/i915/intel_fbc.c 160 :doc: Frame Buffer Compression (FBC) 161 162.. kernel-doc:: drivers/gpu/drm/i915/intel_fbc.c 163 :internal: 164 165Display Refresh Rate Switching (DRRS) 166------------------------------------- 167 168.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 169 :doc: Display Refresh Rate Switching (DRRS) 170 171.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 172 :functions: intel_dp_set_drrs_state 173 174.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 175 :functions: intel_edp_drrs_enable 176 177.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 178 :functions: intel_edp_drrs_disable 179 180.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 181 :functions: intel_edp_drrs_invalidate 182 183.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 184 :functions: intel_edp_drrs_flush 185 186.. kernel-doc:: drivers/gpu/drm/i915/intel_dp.c 187 :functions: intel_dp_drrs_init 188 189DPIO 190---- 191 192.. kernel-doc:: drivers/gpu/drm/i915/intel_dpio_phy.c 193 :doc: DPIO 194 195CSR firmware support for DMC 196---------------------------- 197 198.. kernel-doc:: drivers/gpu/drm/i915/intel_csr.c 199 :doc: csr support for dmc 200 201.. kernel-doc:: drivers/gpu/drm/i915/intel_csr.c 202 :internal: 203 204Video BIOS Table (VBT) 205---------------------- 206 207.. kernel-doc:: drivers/gpu/drm/i915/intel_bios.c 208 :doc: Video BIOS Table (VBT) 209 210.. kernel-doc:: drivers/gpu/drm/i915/intel_bios.c 211 :internal: 212 213.. kernel-doc:: drivers/gpu/drm/i915/intel_vbt_defs.h 214 :internal: 215 216Memory Management and Command Submission 217======================================== 218 219This sections covers all things related to the GEM implementation in the 220i915 driver. 221 222Batchbuffer Parsing 223------------------- 224 225.. kernel-doc:: drivers/gpu/drm/i915/i915_cmd_parser.c 226 :doc: batch buffer command parser 227 228.. kernel-doc:: drivers/gpu/drm/i915/i915_cmd_parser.c 229 :internal: 230 231Batchbuffer Pools 232----------------- 233 234.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_batch_pool.c 235 :doc: batch pool 236 237.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_batch_pool.c 238 :internal: 239 240Logical Rings, Logical Ring Contexts and Execlists 241-------------------------------------------------- 242 243.. kernel-doc:: drivers/gpu/drm/i915/intel_lrc.c 244 :doc: Logical Rings, Logical Ring Contexts and Execlists 245 246.. kernel-doc:: drivers/gpu/drm/i915/intel_lrc.c 247 :internal: 248 249Global GTT views 250---------------- 251 252.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_gtt.c 253 :doc: Global GTT views 254 255.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_gtt.c 256 :internal: 257 258GTT Fences and Swizzling 259------------------------ 260 261.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_fence.c 262 :internal: 263 264Global GTT Fence Handling 265~~~~~~~~~~~~~~~~~~~~~~~~~ 266 267.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_fence.c 268 :doc: fence register handling 269 270Hardware Tiling and Swizzling Details 271~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 272 273.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_fence.c 274 :doc: tiling swizzling details 275 276Object Tiling IOCTLs 277-------------------- 278 279.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_tiling.c 280 :internal: 281 282.. kernel-doc:: drivers/gpu/drm/i915/i915_gem_tiling.c 283 :doc: buffer object tiling 284 285Buffer Object Eviction 286---------------------- 287 288This section documents the interface functions for evicting buffer 289objects to make space available in the virtual gpu address spaces.
