* [PATCH] Pass struct dev pointer to dma_cache_sync()Ralf Baechle2006-12-071-1/+1
| | | | | | | | | | | | | | | | | Pass struct dev pointer to dma_cache_sync() dma_cache_sync() is ill-designed in that it does not have a struct device pointer argument which makes proper support for systems that consist of a mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync to take a struct device pointer as first argument and fix all its callers to pass it.

* sh: sh775x/titan fixes for irq header changes.Jamie Lenehan2006-12-062-33/+31
| | | | | | | | | | | | | | | | | | | | | The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

* sh: Fixup various PAGE_SIZE == 4096 assumptions.Paul Mundt2006-12-063-11/+6
| | | | | | | | | | | | | | | | | | | | | | There were a number of places that made evil PAGE_SIZE == 4k assumptions that ended up breaking when trying to play with 8k and 64k page sizes, this fixes those up. The most significant change is the way we load THREAD_SIZE, previously this was done via: mov #(THREAD_SIZE >> 8), reg shll8 reg to avoid a memory access and allow the immediate load. With a 64k PAGE_SIZE, we're out of range for the immediate load size without resorting to special instructions available in later ISAs (movi20s and so on). The "workaround" for this is to bump up the shift to 10 and insert a shll2, which gives a bit more flexibility while still being much cheaper than a memory access.

* sh: Preliminary support for SH-X2 MMU.Paul Mundt2006-12-064-144/+324
| | | | | | | | | | | | | | | | | | | This adds some preliminary support for the SH-X2 MMU, used by newer SH-4A parts (particularly SH7785). This MMU implements a 'compat' mode with SH-X MMUs and an 'extended' mode for SH-X2 extended features. Extended features include additional page sizes (8kB, 4MB, 64MB), as well as the addition of page execute permissions. The extended mode attributes are placed in a second data array, which requires us to switch to 64-bit PTEs when in X2 mode. With the addition of the exec perms, we also overhaul the mmap prots somewhat, now that it's possible to handle them more intelligently. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | This drops the various IRQ headers that were floating around and primarily providing hardcoded IRQ definitions for the various CPU subtypes.

Centralising the definition in linux/types.h means that arch maintainers don't need to bother adding it, as well as fixing the problem with x86-64 users being asked to make a decision that has absolutely no effect.

* sh: Fix IPR-IRQ's for IRQ-chip change breakage.Jamie Lenehan2006-10-311-2/+8
| | | | | | | | | | | | | | | The conversion from IPR-IRQ to IRQ-chip resulted in the ipr data being allocated in a local variable in make_ipr_irq - breaking anything using IPR interrupts. This changes all of the callers of make_ipr_irq to allocate a static structure containing the IPR data which is then passed to make_ipr_irq.

| | | | | | | | | | | | | Currently the INTC2 code contains a fixed IRQ table that it iterates through to set the handler type, we move this in to the CPU subtype setup code instead and allow for submitting the table that way.

* [PATCH] Directed yield: cpu_relax variants for spinlocks and rw-locksMartin Schwidefsky2006-10-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | On systems running with virtual cpus there is optimization potential in regard to spinlocks and rw-locks. If the virtual cpu that has taken a lock is known to a cpu that wants to acquire the same lock it is beneficial to yield the timeslice of the virtual cpu in favour of the cpu that has the lock (directed yield). With CONFIG_PREEMPT="n" this can be implemented by the architecture without common code changes. Powerpc already does this. With CONFIG_PREEMPT="y" the lock loops are coded with _raw_spin_trylock, _raw_read_trylock and _raw_write_trylock in kernel/spinlock.c. If the lock could not be taken cpu_relax is called. A directed yield is not possible because cpu_relax doesn't know anything about the lock. To be able to yield the lock in favour of the current lock holder variants of cpu_relax for spinlocks and rw-locks are needed. The new _raw_spin_relax, _raw_read_relax and _raw_write_relax primitives differ from cpu_relax insofar that they have an argument: a pointer to the lock structure.
