| * | ARM: mach-shmobile: Use shared clock frameworkMagnus Damm2010-05-201-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Teach SH-Mobile ARM how to make use of the shared SH clock framework. This commit is one atomic switch that dumps the local hackery and instead links in the shared clock framework code in drivers/sh. A few local functions are kept in clock.c.

* sh: move sh clock.c contents to drivers/sh/clk.Magnus Damm2010-05-132-0/+549
| | | | | | | | | | | | | | | | | This patch is V2 of the SH clock framework move from arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All code except the following functions are moved: clk_init(), clk_get() and clk_put(). The init function is still kept in clock.c since it depends on the SH-specific machvec implementation. The symbols clk_get() and clk_put() already exist in the common ARM clkdev code, those symbols are left in the SH tree to avoid duplicating them for SH-Mobile ARM.

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* | sh: intc: IRQ auto-distribution support.Paul Mundt2010-04-152-52/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements support for hardware-managed IRQ balancing as implemented by SH-X3 cores (presently only hooked up for SH7786, but can probably be carried over to other SH-X3 cores, too). CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask.

| | | | | | | | | | | | | | | | | | | | | | This adds support for hardware-assisted userspace irq masking for special priority levels. Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This hooks up the ->set_affinity() for the INTC controllers, which can be done as just a simple copy of the cpumask. The enable/disable paths already handle SMP register strides, so we just test the affinity mask in these paths to determine which strides to skip over. The early enable/disable path happens prior to the IRQs being registered, so we have no affinity mask established at that point, in which case we just default to CPU_MASK_ALL. This is left as it is to permit the force enable/disable code to retain existing semantics. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Use dummy_irq_chip for INTC redirect vectors.Paul Mundt2010-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Presently there's an ordering issue with the chained handler change which places the set_irq_chip() after set_irq_chained_handler(). This causes a warning to be emitted as the IRQ chip needs to be set first. However, there is the caveat that redirect IRQs can't use the parent IRQ's irq chip as they are just dummy redirects, resulting in intc_enable() blowing up when set_irq_chained_handler() attempts to start up the redirect IRQ. In these cases we can just use dummy_irq_chip directly, as we already extract the parent IRQ and chip from the redirect handler. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

The idea is that INTC tables should go from using the macro(s) DECLARE_INTC_DESC..() only to using struct intc_desc with name and hw initialized using the macro INTC_HW_DESC().

* sh: intc: Handle legacy IRQ reservation in vector map.Paul Mundt2009-11-021-0/+25
| | | | | | | | | | | | | Different CPUs will have different starting vectors, with varying amounts of reserved or unusable vector space prior to the first slot. This introduces a legacy vector reservation system that inserts itself in between the CPU vector map registration and the platform specific IRQ setup. This works fine in practice as the only new vectors that boards need to establish on their own should be dynamically allocated rather than arbitrarily assigned. As a plus, this also makes all of the converted platforms sparseirq ready. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc: dynamic IRQ support.Paul Mundt2009-11-021-1/+83
| | | | | | | | | | | | | | | | | | | | | | | This adds support for dynamic IRQ allocation/deallocation for all parts using the SH-style vectored IRQs. While this is not inherently INTC-specific, the INTC code is the main tie-in for vectored IRQ registration, and is the only place that a full view of the utilized vector map is possible. The implementation is fairly straightforward, implementing a flat IRQ map where each registered vector is reserved, allowing us to scan for holes and dynamically wire up IRQs lazily later on in the boot stage. This piggybacks on top of sparseirq in order to make the best use of the available vector space. Dynamic IRQs can be used for any number of things, ranging from MSI in the SH-X3 PCIe case down to demux vectors for board FPGAs and system controllers that presently allocate an arbitrary range. In the latter case, this also allows those platforms to use sparseirq without blowing up, which brings us one step closer to enabling sparseirq as the default for all platform and CPU combinations.

As these are the primary call paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready. There is the added benefit now that each CPU contains specific IPR and INTC tables, so only the vectors with interrupt sources backing them will ever see an irq_desc instantiation. This effectively packs irq_desc down to match the CPU, rather than padding NR_IRQS out to cover the valid vector range. Boards with extra sources will still have to fiddle with the nr_irqs setting, but they can continue doing so through the machvec as before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
