Make the settings of interrupt priorities used by various services configurable at run time. Signed-off-by:

Optimise do_csum() to gang up the loads so they're less likely to get interruptions between. Signed-off-by:

Implement atomic ops using the atomic ops unit available in the AM34 CPU. This allows the equivalent of the LL/SC instructions to be found on other CPUs. Signed-off-by:

Akira Takeuchi authored
Make the FPU operate in non-lazy mode under SMP so that when the process that is currently using the FPU migrates to a different CPU, we don't have to ping its previous CPU to flush the FPU context. Signed-off-by:

Implement global TLB flushing for MN10300. This will be used by the AM34 which is SMP capable. Signed-off-by:
-
Akira Takeuchi authored
Use the [ID]PTEL2 registers rather than [ID]PTEL for TLB control as the bits are a more suitable layout. Signed-off-by:

Akira Takeuchi authored
Make controllable the use of the PIDR register to mark TLB entries as belonging to particular processes. Signed-off-by:
-
David Howells authored
Rename __flush_tlb*() to local_flush_tlb*() as it's more appropriate, and ready to differentiate local from global TLB flushes when SMP is introduced. Whilst we're at it, get rid of __flush_tlb_global() and make local_flush_tlb_page() take an mm_struct pointer rather than VMA pointer. Signed-off-by: -
Akira Takeuchi authored
An AM34 erratum requires MMUCTR read and write on entry to certain exceptions, prior to EPSW.NMID being cleared to allow NMIs to happen. Signed-off-by:

Akira Takeuchi authored
Make the boot wrapper able to use writeback caching, including flushing the cache before jumping to the main kernel. Signed-off-by:

Akira Takeuchi authored
Implement SMP global cache flushing for MN10300. This will be used by the AM34 which is SMP capable. Signed-off-by:
-
David Howells authored
The AM34 core is able to do cache snooping, and so can skip some of the cache flushing. Signed-off-by: -
Akira Takeuchi authored
The AM34 CPU core provides an automated way of purging the cache rather than manually iterating over all the tags in the cache. Make it possible to use these. Signed-off-by:
-
Akira Takeuchi authored
Differentiate local cache flushing from global cache flushing so that they can be done differently on SMP systems. Rename the cache functions from: mn10300_[id]cache_*() to: mn10300_[id]_localcache_*() and on a UP system, assign the global labels to the local labels. Signed-off-by:
-
Akira Takeuchi authored
The functions that perform cache flushing should take addresses of unsigned long type, not unsigned int. Signed-off-by:
-
David Howells authored
The current cache flush and invalidate routines operate by controlling the cache tag registers. Rename the files and add config items to select them. This makes it easier to support the use of other cache flush methods instead, such as the use of AM34's area purge registers, if available. Signed-off-by: -
David Howells authored
Reorder asm/cacheflush.h to put arch primitives first, before the main functions so that the main functions can be inline asm rather than #defines when non-trivial. Signed-off-by: -
David Howells authored
Provide a MN10300_CACHE_ENABLED config option as inverted logic of MN10300_CACHE_DISABLED to make things simpler. Signed-off-by: -
David Howells authored
Split the cache bits out of arch/mn10300/Kconfig as they're quite complex. Signed-off-by: -
Akira Takeuchi authored
Remove the monitor trap function and the set_jtag_stub function as they're not really necessary. Signed-off-by:
-
Akira Takeuchi authored
Add CPU register declarations for the AM34 subarch. Signed-off-by:
-
Akira Takeuchi authored
Don't hard code the cacheline size in the cache control register definitions. Signed-off-by:
-
Akira Takeuchi authored
Move the DMA engine control register definitions to the MN103E010 processor directory so that the MN2WS0050 processor can have its own. Signed-off-by:
-
Akira Takeuchi authored
Differentiate AM33_2 and AM33_3 CPU cores in configuration. The MN103E010 processor contains an AM33_2 core. Whilst we're at it, prepare for AM34-based stuff by declaring AM34_2 too. Signed-off-by:
-
Akira Takeuchi authored
The local_irq_disable() function and co. merely raise the interrupt mask on the MN10300 arch to exclude normal interrupts. This still lets other, higher priority maskable interrupts through, such as are used to service gdbstub's serial port and the MN10300 on-chip serial port virtual FIFOs. Provide functions to allow the maskable interrupts to be fully disabled, which will exclude those interrupts. Signed-off-by:

Add reads[bwl]() and writes[bwl]() for MN10300. Signed-off-by:
-
Akira Takeuchi authored
Don't cast away the volatile in test_bit()'s parameter when we change its type from const volatile void * so that we can dereference it. Signed-off-by:
-
David Howells authored
Typedef the pointer to the function to be called by smp_call_function() and friends: typedef void (*smp_call_func_t)(void *info); as it is used in a fair number of places. Signed-off-by: -
David Howells authored
Prevent cnt32_to_63() from being preempted in sched_clock() because it may read its internal counter, get preempted, get delayed for more than the half period of the 'TSC' and then write the internal counter, thus corrupting it. Whilst some callers of sched_clock() have interrupts disabled or hold spinlocks, not all do, and so preemption must be held here. Note that sched_clock() is called from lockdep, but that shouldn't be a problem because although preempt_disable() calls into lockdep, lockdep has a recursion counter to deal with this.
