From 2848f048616c2c97f02701386ee73137a1307e2c Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Thu, 24 Jan 2008 11:46:45 -0800 Subject: Switch from PIPE_VBLANK to PIPE_EVENT interrupts. My 965GM gets interrupts stuck when using the old PIPE_VBLANK interrupt. Switch to the PIPE_EVENT interrupt mechanism, and set the PIPE*STAT registers to use START_VBLANK on 965 and VBLANK on previous chips. --- shared-core/i915_drv.h | 48 ++++++++++++++++++++++++++++++++++++++++++------ 1 file changed, 42 insertions(+), 6 deletions(-) (limited to 'shared-core/i915_drv.h') diff --git a/shared-core/i915_drv.h b/shared-core/i915_drv.h index 4d3ac0a5..570fc4d3 100644 --- a/shared-core/i915_drv.h +++ b/shared-core/i915_drv.h @@ -466,10 +466,23 @@ extern int i915_wait_ring(struct drm_device * dev, int n, const char *caller); /* Interrupt bits: */ -#define USER_INT_FLAG (1<<1) -#define VSYNC_PIPEB_FLAG (1<<5) -#define VSYNC_PIPEA_FLAG (1<<7) -#define HWB_OOM_FLAG (1<<13) /* binner out of memory */ +#define I915_PIPE_CONTROL_NOTIFY_INTERRUPT (1<<18) +#define I915_DISPLAY_PORT_INTERRUPT (1<<17) +#define I915_RENDER_COMMAND_PARSER_ERROR_INTERRUPT (1<<15) +#define I915_GMCH_THERMAL_SENSOR_EVENT_INTERRUPT (1<<14) +#define I915_HWB_OOM_INTERRUPT (1<<13) /* binner out of memory */ +#define I915_SYNC_STATUS_INTERRUPT (1<<12) +#define I915_DISPLAY_PLANE_A_FLIP_PENDING_INTERRUPT (1<<11) +#define I915_DISPLAY_PLANE_B_FLIP_PENDING_INTERRUPT (1<<10) +#define I915_OVERLAY_PLANE_FLIP_PENDING_INTERRUPT (1<<9) +#define I915_DISPLAY_PLANE_C_FLIP_PENDING_INTERRUPT (1<<8) +#define I915_DISPLAY_PIPE_A_VBLANK_INTERRUPT (1<<7) +#define I915_DISPLAY_PIPE_A_EVENT_INTERRUPT (1<<6) +#define I915_DISPLAY_PIPE_B_VBLANK_INTERRUPT (1<<5) +#define I915_DISPLAY_PIPE_B_EVENT_INTERRUPT (1<<4) +#define I915_DEBUG_INTERRUPT (1<<2) +#define I915_USER_INTERRUPT (1<<1) + #define I915REG_HWSTAM 0x02098 #define I915REG_INT_IDENTITY_R 0x020a4 @@ -513,8 +526,31 @@ extern int i915_wait_ring(struct drm_device * dev, int n, const char *caller); #define PIPE_PIXEL_MASK 0x00ffffff #define PIPE_PIXEL_SHIFT 0 -#define I915_VBLANK_INTERRUPT_ENABLE (1UL<<17) -#define I915_VBLANK_CLEAR (1UL<<1) +#define I915_FIFO_UNDERRUN_STATUS (1UL<<31) +#define I915_CRC_ERROR_ENABLE (1UL<<29) +#define I915_CRC_DONE_ENABLE (1UL<<28) +#define I915_GMBUS_EVENT_ENABLE (1UL<<27) +#define I915_VSYNC_INTERRUPT_ENABLE (1UL<<25) +#define I915_DISPLAY_LINE_COMPARE_ENABLE (1UL<<24) +#define I915_DPST_EVENT_ENABLE (1UL<<23) +#define I915_LEGACY_BLC_EVENT_ENABLE (1UL<<22) +#define I915_ODD_FIELD_INTERRUPT_ENABLE (1UL<<21) +#define I915_EVEN_FIELD_INTERRUPT_ENABLE (1UL<<20) +#define I915_START_VBLANK_INTERRUPT_ENABLE (1UL<<18) /* 965 or later */ +#define I915_VBLANK_INTERRUPT_ENABLE (1UL<<17) +#define I915_OVERLAY_UPDATED_ENABLE (1UL<<16) +#define I915_CRC_ERROR_INTERRUPT_STATUS (1UL<<13) +#define I915_CRC_DONE_INTERRUPT_STATUS (1UL<<12) +#define I915_GMBUS_INTERRUPT_STATUS (1UL<<11) +#define I915_VSYNC_INTERRUPT_STATUS (1UL<<9) +#define I915_DISPLAY_LINE_COMPARE_STATUS (1UL<<8) +#define I915_DPST_EVENT_STATUS (1UL<<7) +#define I915_LEGACY_BLC_EVENT_STATUS (1UL<<6) +#define I915_ODD_FIELD_INTERRUPT_STATUS (1UL<<5) +#define I915_EVEN_FIELD_INTERRUPT_STATUS (1UL<<4) +#define I915_START_VBLANK_INTERRUPT_STATUS (1UL<<2) /* 965 or later */ +#define I915_VBLANK_INTERRUPT_STATUS (1UL<<1) +#define I915_OVERLAY_UPDATED_STATUS (1UL<<0) #define SRX_INDEX 0x3c4 #define SRX_DATA 0x3c5 -- cgit v1.2.3
