| | | | | | | Now that the common 8250 serial driver supports an "irqflags" field, we don't need to patch in a custom define into the code. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add new cacheflush syscallSonic Zhang2010-10-224-1/+26
| | | | | | | | | | | | Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | Nothing actually needs to use these MMRs (as direct cache manipulation is done with the DTEST MMRs), so simply hide the read funcs behind the anomaly define.

| * Fix IRQ flag handling namingDavid Howells2010-10-071-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

| * Blackfin: Rename IRQ flags handling functionsDavid Howells2010-10-074-147/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename h/w IRQ flags handling functions to be in line with what is expected for the irq renaming patch. This renames local_*_hw() to hard_local_*() using the following perl command: perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"` and then fixing up asm/irqflags.h manually. Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both return the flags rather than passing it through the argument list. Signed-off-by: David Howells <dhowells@redhat.com>

* | spi/bfin_spi: redo GPIO CS handlingBarry Song2010-10-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The common SPI layers take care of detecting CS conflicts and preventing two devices from claiming the same CS. This causes problems for the GPIO CS support we currently have as we are using CS0 to mean "GPIO CS". But if we have multiple devices using a GPIO CS, the common SPI layers see multiple devices using the virtual "CS0" and reject any such attempts. To make both work, we introduce an offset define. This represents the max number of hardware CS values that the SPI peripheral supports. If the CS is below this limit, we know we can use the hardware CS. If it's above, we treat it as a GPIO CS. This keeps the CS unique as seen by the common code and prevents conflicts. Signed-off-by: Barry Song <barry.song@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* dma-mapping: remove dma_is_consistent APIFUJITA Tomonori2010-08-111-1/+0
| | | | | | | | | | | | | | | | | | | | | Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

* dma-mapping: unify dma_get_cache_alignment implementationsFUJITA Tomonori2010-08-111-1/+0
| | | | | | | | | | | | | | | | dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue.

* dma-mapping: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGNFUJITA Tomonori2010-08-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).

* | Blackfin: move string functions to normal lib/ assemblyRobin Getz2010-05-221-109/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 'extern inline' doesn't work correctly in the context of the Linux kernel (too many overriding defines), move the string functions to normal lib/ assembly files (like the existing mem funcs). This avoids the forced inline all over the kernel and allows us to place them constantly in L1. This also avoids some module failures when gcc inserts calls to string functions but the kernel build system doesn't fully consult the library archives.

* | Blackfin: add support for the DBG (debug output) pseudo insnRobin Getz2010-05-221-0/+1
| | | | | | | | | | | | | | | | Another pseudo insn used by Blackfin simulators. Also factor some now common register lookup code out of the DBGA handlers. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* | Blackfin: change the BUG opcode to an unused 16-bit opcodeRobin Getz2010-05-221-1/+6
| | | | | | | | | | | | | | | | | | The current BUG opcode includes the bit that flags the insn as a 32bit opcode, but it wasn't declaring it as 32bits. So pick an unused 16bit.

* | Blackfin: add support for the DBGA (debug assert) pseudo insnRobin Getz2010-05-221-0/+17
| | | | | | | | | | | | | | | | | | | | | | A few pseudo debug insns exist to make testing of simulators easier. Since these don't actually exist in the hardware, we have to have the exception handler take care of emulating these. This allows sim test cases to be executed unmodified under Linux and thus simplify debugging greatly.
