2009-06-15powerpc/cell: Extract duplicated IOPTE_* to <asm/iommu.h>Geert Uytterhoeven1-10/+0
Both arch/powerpc/platforms/cell/iommu.c and arch/powerpc/platforms/ps3/mm.c contain the same Cell IOMMU page table entry definitions. Extract them and move them to <asm/iommu.h>, while adding a CBE_ prefix. This also allows them to be used by drivers.

2008-01-25[POWERPC] PS3: Use the HVs storage device notification mechanism properlyGeert Uytterhoeven1-2/+0
The PS3 hypervisor has a storage device notification mechanism to wait until a storage device is ready. Unfortunately the storage device probing code used this mechanism in an incorrect way, needing a polling loop and handling of devices that are not yet ready. This change corrects this by: - First waiting for the reception of an asynchronous notification that a new storage device became ready, - Then looking up the storage device in the device repository. On shutdown, the storage probe thread is stopped and the storage notification device is closed using a reboot notifier.

2008-01-25[POWERPC] PS3: Add ps3_repository_find_device_by_id()Geert Uytterhoeven1-0/+2
The storage probe feature of the PS3 hypervisor returns device IDs. Add the corresponding repository routine ps3_repository_find_device_by_id() which can be used to retrieve the device info from the repository.

2008-01-25[POWERPC] PS3: Make bus_id and dev_id u64Geert Uytterhoeven1-6/+6
Change the PS3 bus_id and dev_id from type unsigned int to u64. These IDs are 64-bit in the repository, and the special storage notification device has a device ID of ULONG_MAX.

2007-10-09[POWERPC] PS3: Save os-area params to device treeGeoff Levand1-0/+1
Add the PS3 os-area startup params to the device tree. This allows a second stage kernel loaded with kexec to use these values. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2007-10-09[POWERPC] PS3: Add os-area rtc_diff set/get routinesGeoff Levand1-1/+2
Updates for PS3 os-area rtc_diff set/get routines o Add a new routine ps3_os_area_set_rtc_diff(). o Rename ps3_os_area_rtc_diff() to ps3_os_area_get_rtc_diff(). o Remove static variable rtc_shift with calls to ps3_os_area_get_rtc_diff().

2007-09-14[POWERPC] PS3: Fix CONFIG_SMP=n, CONFIG_KEXEC=y buildJeremy Kerr1-0/+4
Currently, the ps3 kernel fails to build without smp but with kexec, as ps3_kexec_cpu_down needs ps3_smp_cleanup_cpu, which isn't defined on UP kernels. This change adds an empty ps3_smp_cleanup_cpu for UP kernels. Booted on ps3.

2007-09-11[POWERPC] cell/PS3: Ignore storage devices that are still being probedGeert Uytterhoeven1-0/+1
On PS3, A storage device may show up in the repository before the hypervisor has finished probing: - If its type is not yet known, it shows up as PS3_DEV_TYPE_STOR_DUMMY, - If its regions are being probed, it shows up as having zero regions. If any of these happen, consider the device not yet present. The storage probe thread will retry later. This fixes the timing-dependent problem where a kernel booted from FLASH ROM sometimes cannot find the hard disk.

2007-06-28[POWERPC] PS3: Repository probe cleanupsGeoff Levand1-11/+20
Repository updates: - Extract ps3_repository_find_bus() from ps3_repository_find_device(), as the storage driver needs it. - Make ps3_repository_find_device() return -ENODEV if a device is not found, just like if a bus is not found. - Add ps3_repository_read_vuart_sysmgr_port() and ps3_repository_read_vuart_av_port() to get vuart port info. - Add device enumeration routines ps3_repository_find_device() and ps3_repository_find_devices(). - Cleanup debug routines.

2007-06-28[POWERPC] PS3: System-bus reworkGeoff Levand1-0/+11
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).
