From a147df879b3b850612222759c14f4142d2406e74 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 24 Apr 2003 19:09:55 +0000 Subject: Remove more gamma DMA infrastructure. Most of this code was copied straight from linux, so it could be added back if some driver needed it in the future. --- bsd-core/drmP.h | 48 ------------------------------------------------ 1 file changed, 48 deletions(-) (limited to 'bsd-core/drmP.h') diff --git a/bsd-core/drmP.h b/bsd-core/drmP.h index 9b8dd57e..28594f76 100644 --- a/bsd-core/drmP.h +++ b/bsd-core/drmP.h @@ -52,12 +52,6 @@ #ifndef __HAVE_DMA_IRQ #define __HAVE_DMA_IRQ 0 #endif -#ifndef __HAVE_DMA_WAITLIST -#define __HAVE_DMA_WAITLIST 0 -#endif -#ifndef __HAVE_DMA_FREELIST -#define __HAVE_DMA_FREELIST 0 -#endif #define DRM_DEBUG_CODE 0 /* Include debugging code (if > 1, then also include looping detection. */ @@ -159,12 +153,9 @@ typedef struct drm_buf { void *address; /* Address of buffer */ unsigned long bus_address; /* Bus address of buffer */ struct drm_buf *next; /* Kernel-only: used for free list */ - __volatile__ int waiting; /* On kernel DMA queue */ __volatile__ int pending; /* On hardware DMA queue */ - wait_queue_head_t dma_wait; /* Processes waiting */ DRMFILE filp; /* Unique identifier of holding process */ int context; /* Kernel queue for this buffer */ - int while_locked;/* Dispatch this buffer while locked */ enum { DRM_LIST_NONE = 0, DRM_LIST_FREE = 1, @@ -194,10 +185,8 @@ typedef struct drm_freelist { atomic_t count; /* Number of free buffers */ drm_buf_t *next; /* End pointer */ - wait_queue_head_t waiting; /* Processes waiting on free bufs */ int low_mark; /* Low water mark */ int high_mark; /* High water mark */ - atomic_t wfh; /* If waiting for high mark */ DRM_SPINTYPE lock; } drm_freelist_t; @@ -230,24 +219,6 @@ struct drm_file { struct drm_device *devXX; }; -typedef struct drm_queue { - atomic_t use_count; /* Outstanding uses (+1) */ - atomic_t finalization; /* Finalization in progress */ - atomic_t block_count; /* Count of processes waiting */ - atomic_t block_read; /* Queue blocked for reads */ - wait_queue_head_t read_queue; /* Processes waiting on block_read */ - atomic_t block_write; /* Queue blocked for writes */ - wait_queue_head_t write_queue; /* Processes waiting on block_write */ -#if 1 - atomic_t total_queued; /* Total queued statistic */ - atomic_t total_flushed;/* Total flushes statistic */ - atomic_t total_locks; /* Total locks statistics */ -#endif - drm_ctx_flags_t flags; /* Context preserving and 2D-only */ - drm_waitlist_t waitlist; /* Pending buffers */ - wait_queue_head_t flush_queue; /* Processes waiting until flush */ -} drm_queue_t; - typedef struct drm_lock_data { drm_hw_lock_t *hw_lock; /* Hardware lock */ DRMFILE filp; /* Unique identifier of holding process (NULL is kernel)*/ @@ -271,8 +242,6 @@ typedef struct drm_device_dma { /* DMA support */ drm_buf_t *this_buffer; /* Buffer being sent */ drm_buf_t *next_buffer; /* Selected buffer to send */ - drm_queue_t *next_queue; /* Queue from which buffer selected*/ - wait_queue_head_t waiting; /* Processes waiting on free bufs */ } drm_device_dma_t; #if __REALLY_HAVE_AGP @@ -366,7 +335,6 @@ struct drm_device { /* Memory management */ drm_map_list_t *maplist; /* Linked list of regions */ - int map_count; /* Number of mappable regions */ drm_local_map_t **context_sareas; int max_context; @@ -374,10 +342,6 @@ struct drm_device { drm_lock_data_t lock; /* Information on hardware lock */ /* DMA queues (contexts) */ - int queue_count; /* Number of active DMA queues */ - int queue_reserved; /* Number of reserved DMA queues */ - int queue_slots; /* Actual length of queuelist */ - drm_queue_t **queuelist; /* Vector of pointers to DMA queues */ drm_device_dma_t *dma; /* Optional pointer for DMA support */ /* Context support */ @@ -391,13 +355,8 @@ struct drm_device { #endif void *irqh; /* Handle from bus_setup_intr */ atomic_t context_flag; /* Context swapping flag */ - atomic_t interrupt_flag; /* Interruption handler flag */ - atomic_t dma_flag; /* DMA dispatch flag */ struct callout timer; /* Timer for delaying ctx switch */ - wait_queue_head_t context_wait; /* Processes waiting on ctx switch */ - int last_checked; /* Last context checked for DMA */ int last_context; /* Last current context */ - unsigned long last_switch; /* jiffies at last context switch */ #if __FreeBSD_version >= 400005 struct task task; #endif @@ -505,13 +464,6 @@ extern int DRM(waitlist_destroy)(drm_waitlist_t *bl); extern int DRM(waitlist_put)(drm_waitlist_t *bl, drm_buf_t *buf); extern drm_buf_t *DRM(waitlist_get)(drm_waitlist_t *bl); #endif -#if __HAVE_DMA_FREELIST -extern int DRM(freelist_create)(drm_freelist_t *bl, int count); -extern int DRM(freelist_destroy)(drm_freelist_t *bl); -extern int DRM(freelist_put)(drm_device_t *dev, drm_freelist_t *bl, - drm_buf_t *buf); -extern drm_buf_t *DRM(freelist_get)(drm_freelist_t *bl, int block); -#endif #endif /* __HAVE_DMA */ #if __HAVE_VBL_IRQ extern int DRM(vblank_wait)(drm_device_t *dev, unsigned int *vbl_seq); -- cgit v1.2.3
