2007-12-19[POWERPC] cell: catch errors from sysfs_create_group()Jeremy Kerr
We're currently getting a warning from not checking the result of sysfs_create_group, which is declared as __must_check. This change introduces appropriate error-handling for spu_add_sysdev_attr_group() Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-12-19[POWERPC] cell: handle SPE kernel mappings that cross segment boundariesJeremy Kerr
Currently, we have a possibilty that the SLBs setup during context switch don't cover the entirety of the necessary lscsa and code regions, if these regions cross a segment boundary. This change checks the start and end of each region, and inserts a SLB entry for each, if unique. We also remove the assumption that the spu_save_code and spu_restore_code reside in the same segment, by using the specific code array for save and restore.

2007-12-19[POWERPC] cell: add spu_64k_pages_available() checkJeremy Kerr
Add a function spu_64k_pages_available(), so that we can abstract the explicity use of mmu_psize_defs() in lssca_alloc.c Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-12-19[POWERPC] cell: use spu_load_slb for SLB setupJeremy Kerr
Now that we have a helper function to setup a SPU SLB, use it for __spu_trap_data_seq. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-12-19[POWERPC] cell: handle kernel SLB setup in spu_base.cJeremy Kerr
Currently, the SPU context switch code (spufs/switch.c) sets up the SPU's SLBs directly, which requires some low-level mm stuff. This change moves the kernel SLB setup to spu_base.c, by exposing a function spu_setup_kernel_slbs() to do this setup. This allows us to remove the low-level mm code from switch.c, making it possible to later move switch.c to the spufs module. Also, add a struct spu_slb for the cases where we need to deal with SLB entries. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2007-12-19[POWERPC] cell: safer of_has_vicinity routineAndre Detsch
This patch changes the way we check for the existence of vicinity property in spe device nodes. The new implementation does not depend on having an initialized cbe_spu_info[0].spus, and checks for presence of vicinity in all nodes, not only in the first one.

2007-12-19[POWERPC] perfmon2: make pm_interval register read/writeKevin Corry
The pm_interval register in the Cell PMU is read/write, but was implemented in the kernel as write-only. Previously, the written value was saved in a "shadow" copy so calls to cbe_read_pm() could return the value. Perfmon2 needs to be able to read the current values of pm_interval, so change cbe_read_pm() to read the actual register instead of the "shadow" copy. There is currently no code in the kernel that tries to read the pm_interval register with cbe_read_pm() (expecting to receive the "shadow" value), so this should not break any existing code.

2007-12-11[POWERPC] Use SLB size from the device treeMichael Neuling
Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.

2007-12-10powerpc: Fix IDE legacy vs. native fixupsBenjamin Herrenschmidt
PowerMac and CHRP/BriQ platforms have quirks to switch some IDE controllers from legacy mode to fully native mode. Those quirks however will not work properly anymore due to a change to the generic code to better handle legacy IDE resources. This fixes it by moving those quirk to "early" quirks (so they run before resources are probed for the devices) and clearing all BARs after the conversion to force a reallocation of sane values.
