2008-01-31[POWERPC] Cell IOMMU fixed mapping supportMichael Ellerman
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>

2008-01-31[POWERPC] Add support to cell_iommu_setup_page_tables() for multiple windowsMichael Ellerman
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.

2008-01-31[POWERPC] Allocate the hash table under 1G on cellMichael Ellerman
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.

2008-01-30KVM: x86 emulator: Only allow VMCALL/VMMCALL trapped by #UDSheng Yang
When executing a test program called "crashme", we found the KVM guest cannot survive more than ten seconds, then encounterd kernel panic. The basic concept of "crashme" is generating random assembly code and trying to execute it. After some fixes on emulator insn validity judgment, we found it's hard to get the current emulator handle the invalid instructions correctly, for the #UD trap for hypercall patching caused troubles. The problem is, if the opcode itself was OK, but combination of opcode and modrm_reg was invalid, and one operand of the opcode was memory (SrcMem or DstMem), the emulator will fetch the memory operand first rather than checking the validity, and may encounter an error there. For example, ".byte 0xfe, 0x34, 0xcd" has this problem. In the patch, we simply check that if the invalid opcode wasn't vmcall/vmmcall, then return from emulate_instruction() and inject a #UD to guest. With the patch, the guest had been running for more than 12 hours.
