* [POWERPC] Cell IOMMU fixed mapping supportMichael Ellerman2008-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [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.

That is bad for two reasons: (1) it's doing (or trying to do) a scan of all devices when it should only be scanning those on the vio bus, and (2) devices_subsys was an internal symbol of the device system code which was never meant for external use and has now gone away, and thus the kernel fails to compile on pSeries. The new version uses bus_find_device_by_name() on the vio bus (vio_bus_type). Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Not only does it double the size of a spinlock but it changes locking to a potentially less optimal trylock. Put all of that under CONFIG_GENERIC_LOCKBREAK, and introduce a __raw_spin_is_contended that uses the lock data itself to determine whether there are waiters on the lock, to be used if CONFIG_GENERIC_LOCKBREAK is not set. Rename need_lockbreak to spin_needbreak, make it use spin_is_contended to decouple it from the spinlock implementation, and make it typesafe (rwlocks do not have any need_lockbreak sites -- why do they even get bloated up with that break_lock then?).

The new API guarantees protection against the cpu-hotplug operation, but it doesn't guarantee serialized access to any of the local data structures. Hence the changes needs to be reviewed.

Most of the drivers can accept the compatible properties, even if they don't match the what is recommented in the generic names recommended practice document. This patch also adds extra checks so that fixups are not performed blindly. Instead, the code first verifies that the device tree is faulty before making any changes. This way, if the Efika firmware is updated to fix these issues, then the fixups will no longer get applied. At this point; here is the list of fixups needed for the efika: 1. If the device_type property on the root node is 'chrp', then Linux won't boot. Change device_type to 'efika' to avoid this condition 2. Add full interrupt list to the bestcomm node. In actual fact, the bestcomm interrupts property is technically correct, it just doesn't expose the same granularity as the device driver expects. All other 5200 device trees provide a separate irq number for each bestcomm channel. Rather than hack the driver, it's simpler to fix it up 3. /builtin/sound node is missing an interrupts property 4. /builtin/ethernet node is missing a phy-handle property and the device driver doesn't know what to do without one.

The general rule I've applied is that entries for values normally parsed by humans are left in decimal (i.e. IRQ, cache size, clock rates, basic counts and indexes) and all other data (i.e. reg and ranges, IRQ flags etc.) remain in hex. I've used dtc to confirm that the output prior to this changeset matches the output after this changeset is applied for all boards.
