* arch/powerpc/sysdev/fsl_rio.c: correct IECSR register clear valueLiu Gang-B341822011-10-031-2/+3
| | | | | | | | | | | | | | | | | | commit 671ee7f0ce62e4b991b47fcf1c161c3f710dabbc upstream. This bug causes the IECSR register clear failure. In this case, the RETE (retry error threshold exceeded) interrupt will be generated and cannot be cleared. So the related ISR may be called persistently. The RETE bit in IECSR is cleared by writing a 1 to it.

* powerpc/e500: fix breakage with fsl_rio_mcheck_exceptionScott Wood2011-06-221-17/+18
| | | | | | | | | | | | | | | | | | The wrong MCSR bit was being used on e500mc. MCSR_BUS_RBERR only exists on e500v1/v2. Use MCSR_LD on e500mc, and remove all MCSR checking in fsl_rio_mcheck_exception as we now no longer call that function if the appropriate bit in MCSR is not set. If RIO support was enabled at compile-time, but was never probed, just return from fsl_rio_mcheck_exception rather than dereference a NULL pointer. TODO: There is still a remaining, though comparitively minor, issue in that this recovery mechanism will falsely engage if there's an unrelated MCSR_LD event at the same time as a RIO error.

| * powerpc/fsl_rio: Error interrupt handler for sRIO on MPC85xxShaohui Xie2011-05-201-8/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sRIO controller reports errors to the core with one signal, it uses register EPWISR to provides the core quick access to where the error occurred. The EPWISR indicates that there are 4 interrupts sources, port1, port2, message unit and port write receive, but the sRIO driver does not support port2 for now, still the handler takes care of port2. Currently the handler only clear error status without any recovery.

| * | | drivercore: revert addition of of_match to struct deviceGrant Likely2011-05-181-2/+5
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

Also remove the unnecessary cast of irq_get_handler_data in the cascade handler, which is the demux flow handler of the parent msi interrupt. (This is the expected usage for handler_data).

* | | powerpc: Consolidate ipi message mux and demuxMilton Miller2011-05-193-42/+8

The powerpc architecture code is optimised for having 4 distinct ipi triggers, which are mapped to 4 distinct messages (ipi many, ipi single, scheduler ipi, and enter debugger). However, several interrupt controllers only provide a single software triggered interrupt that can be delivered to each cpu. To resolve this limitation, each smp_ops implementation created a per-cpu variable that is manipulated with atomic bitops. Since these lines will be contended they are optimialy marked as shared_aligned and take a full cache line for each cpu. Distro kernels may have 2 or 3 of these in their config, each taking per-cpu space even though at most one will be in use. This consolidation removes smp_message_recv and replaces the single call actions cases with direct calls from the common message recognition loop. The complicated debugger ipi case with its muxed crash handling code is moved to debug_ipi_action which is now called from the demux code (instead of the multi-message action calling smp_message_recv). I put a call to reschedule_action to increase the likelyhood of correctly merging the anticipated scheduler_ipi() hook coming from the scheduler tree; that single required call can be inlined later. The actual message decode is a copy of the old pseries xics code with its memory barriers and cache line spacing, augmented with a per-cpu unsigned long based on the book-e doorbell code. The optional data is set via a callback from the implementation and is passed to the new cause-ipi hook along with the logical cpu number. While currently only the doorbell implemntation uses this data it should be almost zero cost to retrieve and pass it -- it adds a single register load for the argument from the same cache line to which we just completed a store and the register is dead on return from the call. I extended the data element from unsigned int to unsigned long in case some other code wanted to associate a pointer. The doorbell check_self is replaced by a call to smp_muxed_ipi_resend, conditioned on the CPU_DBELL feature. The ifdef guard could be relaxed to CONFIG_SMP but I left it with BOOKE for now. Also, the doorbell interrupt vector for book-e was not calling irq_enter and irq_exit, which throws off cpu accounting and causes code to not realize it is running in interrupt context.

The new core code allows to update the type in irq_data and return IRQ_SET_MASK_OK_NOCOPY, so the core code will not touch it, except for setting the IRQ_LEVEL flag. Retrieve the IRQ_LEVEL information from irq_data which avoids a redundant sparse irq lookup as well. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* powerpc: mpc8xx_pic: Cleanup flow type handlingThomas Gleixner2011-03-291-8/+1
| | | | | | | | | | The core irq_set_type() function updates the flow type when the chip callback returns 0. So setting the type is bogus. The level flag is updated in the core as well. Use the proper accessors for setting the irq handlers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
