| | * | | | sh: intc: Handle legacy IRQ reservation in vector map.Paul Mundt2009-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Remove unused WP signal for SDHI0 and KFR2R09Magnus Damm2009-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of the unused WP signal for SDHI0 on KFR2R09. This because yc304 on KFR2R09 is a Micro SD slot which does not implement the WP signal. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * | | | sh: intc: dynamic IRQ support.Paul Mundt2009-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Presently only the first 2 counters are supported, as these are the ones of the most interest to the perf tool and end users. Counter chaining is not presently handled, so these are simply implemented as 32-bit counters. This also establishes a perf event support framework for other hardware counters, which the existing SH-4 oprofile code will migrate over to as the SH-4A support evolves.
