| * [LINUX] dma: Use swiotlb mask for coherent mappings tookfraser@localhost.localdomain2006-12-203-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change to use a default DMA bit width of 30 bits (required by chips like the b44) only converted the streaming DMA primitives. The coherent mappings are still hard-coded to 31 bits. This means that b44 still doesn't work under Xen. This patch makes the io_tlb_dma_bits variable global and uses it for coherent memory mappings. Thanks to Calvin Webster for providing a machine with a b44 and 2G of memory I've been able to verify that this finally makes the b44 work under Xen. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Rename 'io_tlb_dma_bits' to the more correct 'dma_bits'. This also affects the name of the boot parameter, which is now 'dma_bits='.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mm_lock. Changeset 13018:c98ca86138a7422cdf9b15d87c95619b7277bb6a merely sweeps the bug under the carpet: it silences zap_page_range()'s cries for help by keeping interrupts enabled. That doesn't fix the bug, and it's also wrong: if a critical region gets interrupted, and the interrupt printk()s, xenfb_refresh() gets executed and promptly deadlocks. This patch fixes the locking, but leaves open a race between xenfb_update_screen() and do_no_page(). See the source code for a detailed explanation of how it works, and where it fails.
