| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few places missed the "a" specifier for the __ex_table section. Add these so we avoid generation an additional section at link time. Latest modpost would otherwise complain like this: WARNING: vmlinux.o (__ex_table.2): section name inconsistency. (.[number]+) following section name. Did you forget to use "ax"/"aw" in a .S file? Note that for example <linux/init.h> contains section definitions for use in .S files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for setting up a fixed IOMMU mapping on certain cell machines. For 64-bit devices this avoids the performance overhead of mapping and unmapping pages at runtime. 32-bit devices are unable to use the fixed mapping. The fixed mapping is established at boot, and maps all of physical memory 1:1 into device space at some offset. On machines with < 30 GB of memory we setup the fixed mapping immediately above the normal IOMMU window. For example a machine with 4GB of memory would end up with the normal IOMMU window from 0-2GB and the fixed mapping window from 2GB to 6GB. In this case a 64-bit device wishing to DMA to 1GB would be told to DMA to 3GB, plus any offset required by firmware. The firmware offset is encoded in the "dma-ranges" property. On machines with 30GB or more of memory, we are unable to place the fixed mapping above the normal IOMMU window as we would run out of address space. Instead we move the normal IOMMU window to coincide with the hash page table, this region does not need to be part of the fixed mapping as no device should ever be DMA'ing to it. We then setup the fixed mapping from 0 to 32GB. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Paul Mackerras <paulus@samba.org>

| * | [POWERPC] Add support to cell_iommu_setup_page_tables() for multiple windowsMichael Ellerman2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to cell_iommu_setup_page_tables() for handling two windows, the dynamic window and the fixed window. A fixed window size of 0 indicates that there is no fixed window at all. Currently there are no callers who pass a non-zero fixed window, but the upcoming fixed IOMMU mapping patch will change that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the IOMMU logic out from cell_dma_dev_setup() into a separate function. If we're not using dma_direct_ops or dma_iommu_ops we don't know what the hell's going on, so BUG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split cell_iommu_setup_hardware() into two parts. Split the page table setup into cell_iommu_setup_page_tables() and the bits that kick the hardware into cell_iommu_enable_hardware().

| * | [POWERPC] Split out the logic that allocates struct iommusMichael Ellerman2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split out the logic that allocates a struct iommu into a separate function. This can fail however the calling code has never cared - so just return if we can't allocate an iommu.

| * | [POWERPC] Allocate the hash table under 1G on cellMichael Ellerman2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support the fixed IOMMU mapping (in a subsequent patch), we need the hash table to be inside the IOMMUs DMA window. This is usually 2G, but let's make sure the hash table is under 1G as that will satisfy the IOMMU requirements and also means the hash table will be on node 0.
