Revert "ttm: Include the 'struct dev' when using the DMA API."

This reverts commit 5a893fc28f0393adb7c885a871b8c59e623fd528. This causes a use after free in the ttm free alloc pages path, when it tries to get the be after the be has been destroyed. Signed-off-by: Dave Airlie

ttm: Include the 'struct dev' when using the DMA API.

This makes the accounting when using 'debug_dma_dump_mappings()' and CONFIG_DMA_API_DEBUG=y be assigned to the correct device instead of 'fallback'. No functional change - just cosmetic. Signed-off-by: Konrad Rzeszutek Wilk

ttm: Expand (*populate) to support an array of DMA addresses.

2011-01-27T21:07:58Z

We pass in the array of ttm pages to be populated in the GART/MM of the card (or AGP). Patch titled: "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set." uses the DMA API to make those pages have a proper DMA addresses (in the situation where page_to_phys or virt_to_phys do not give use the DMA (bus) address). Since we are using the DMA API on those pages, we should pass in the DMA address to this function so it can save it in its proper fields (later patches use it).

ttm: Introduce a placeholder for DMA (bus) addresses.

This is right now limited to only non-pool constructs. [v2: Fixed indentation issues, add review-by tag] Reviewed-by: Thomas Hellstrom Signed-off-by: Konrad Rzeszutek Wilk Tested-by: Ian Campbell

drm/ttm: Fix up io_mem_reserve / io_mem_free calling

2010-11-22T03:25:22Z

This patch attempts to fix up shortcomings with the current calling sequences. 1) There's a fastpath where no locking occurs and only io_mem_reserved is called to obtain needed info for mapping. The fastpath is set per memory type manager. 2) If the fastpath is disabled, io_mem_reserve and io_mem_free will be exactly balanced and not called recursively for the same struct ttm_mem_reg. 3) Optionally the driver can choose to enable a per memory type manager LRU eviction mechanism that, when io_mem_reserve returns -EAGAIN will attempt to kill user-space mappings of memory in that manager to free up needed resources Signed-off-by: Thomas Hellstrom Reviewed-by: Ben Skeggs Signed-off-by: Dave Airlie

drm/ttm/vmwgfx: Have TTM manage the validation sequence.

2010-11-22T03:25:21Z

Rather than having the driver supply the validation sequence, leave that responsibility to TTM. This saves some confusion and a function argument. Signed-off-by: Thomas Hellstrom Signed-off-by: Dave Airlie
