2007-06-28[POWERPC] PS3: System-bus reworkGeoff Levand
Rework the PS3 system bus to unify device support. - DMA region sizes must be a power of two - storage bus DMA updates: - Small fixes for the PS3 DMA core: o fix alignment bug o kill superfluous test o indentation o spelling o export ps3_dma_region_{create,free}() - ps3_dma_region_init(): o Add `addr' and `len' parameters, so you can create a DMA region that does not cover all memory (use `NULL' and `0' to cover all memory). This is needed because there are not sufficient IOMMU resources to have all DMA regions cover all memory. o Uninline - Added remove and shutdown routines to all drivers. - Added loadable module support to all drivers. - Added HV calls for iopte management (needed by sound driver).

2007-06-14[POWERPC] Kill typedef-ed structs for hash PTEs and BATsDavid Gibson
Using typedefs to rename structure types if frowned on by CodingStyle. However, we do so for the hash PTE structure on both ppc32 (where it's called "PTE") and ppc64 (where it's called "hpte_t"). On ppc32 we also have such a typedef for the BATs ("BAT"). This removes this unhelpful use of typedefs, in the process bringing ppc32 and ppc64 closer together, by using the name "struct hash_pte" in both cases.

2007-05-02[POWERPC] Fix STRICT_MM_TYPECHECKSDavid Gibson
Since we don't have it active by default, the STRICT_MM_TYPECHECKS option has bitrotted again. This patch fixes a couple of simple build fixes if the option is selected. First, pud_t mustn't be defined in page.h on 32-bit systems, because it conflicts with the version in the generic pud-folding code. Second, pci_32.c is missing a __pgprot() wrapper call. Third, a couple of PS3 files use constants of type pgprot_t when they need the raw values, we add pgprot_val() calls to fix this.

Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory.

2006-12-04[POWERPC] ps3: multiplatform build fixesArnd Bergmann
A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL. This may change if we get oprofile support for PS3. Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
