| * genirq: Clear CPU mask in affinity_hint when none is providedPeter P Waskiewicz Jr2010-05-121-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an interrupt is disabled and torn down, the CPU mask returned through affinity_hint right now is all CPUs. Also, for drivers that don't provide an affinity_hint mask, this can be misleading. There should be no hint at all, meaning an empty CPU mask.

| * genirq: Add CPU mask affinity hintPeter P Waskiewicz Jr2010-05-034-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a cpumask affinity hint to the irq_desc structure, along with a registration function and a read-only proc entry for each interrupt. This affinity_hint handle for each interrupt can be used by underlying drivers that need a better mechanism to control interrupt affinity. The underlying driver can register a cpumask for the interrupt, which will allow the driver to provide the CPU mask for the interrupt to anything that requests it. The intent is to extend the userspace daemon, irqbalance, to help hint to it a preferred CPU mask to balance the interrupt into.

| * genirq: Remove IRQF_DISABLED from core codeThomas Gleixner2010-04-133-31/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove all code which is related to IRQF_DISABLED from the core kernel code. IRQF_DISABLED still exists as a flag, but becomes a NOOP and will be removed after a grace period. That way we can easily revert to the previous behaviour by just restoring the core code.

| * genirq: Run irq handlers with interrupts disabledIngo Molnar2010-04-131-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running interrupt handlers with interrupts enabled can cause stack overflows. That has been observed with multiqueue NICs delivering all their interrupts to a single core. We might band aid that somehow by checking the interrupt stacks, but the real safe fix is to run the irq handlers with interrupts disabled. Drivers for whacky hardware still can reenable them in the handler itself, if the need arises. (They do already due to lockdep) The risk of doing this is rather low: - lockdep already enforces this - CONFIG_NOHZ has shaken out the drivers which relied on jiffies updates - time keeping is not longer sensitive to the timer interrupt being delayed Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Miller <davem@davemloft.net> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Linus Torvalds <torvalds@osdl.org> LKML-Reference: <20100326000405.758579387@linutronix.de>
| * genirq: Introduce request_any_context_irq()Marc Zyngier2010-04-132-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we enjoy threaded interrupts, we're starting to see irq_chip implementations (wm831x, pca953x) that make use of threaded interrupts for the controller, and nested interrupts for the client interrupt. It all works very well, with one drawback: Drivers requesting an IRQ must now know whether the handler will run in a thread context or not, and call request_threaded_irq() or request_irq() accordingly. The problem is that the requesting driver sometimes doesn't know about the nature of the interrupt, specially when the interrupt controller is a discrete chip (typically a GPIO expander connected over I2C) that can be connected to a wide variety of otherwise perfectly supported hardware. This patch introduces the request_any_context_irq() function that mostly mimics the usual request_irq(), except that it checks whether the irq level is configured as nested or not, and calls the right backend. On success, it also returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes the Kconfig menu option. SMD can still be selected but it's done inside the Kconfig file and not via the menu. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
| * | | arm: msm: smd: fix SMD modem processor sync conditionDaniel Walker2010-05-123-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting up we need to wait for the modem processor to partially boot. This is because the modem processor does resource allocation for us. If we don't wait the modem won't honor our requests and we end up crashing or in an unknown state. This change just formalizes the waiting process. Signed-off-by: Daniel Walker <c_dwalke@quicinc.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This irq handler isn't used in all cases, so add the proper ifdef. This eliminates a compiler warning due to the function not getting used. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This just removed some unneeded predefines. One needed a whole function moved down further. The others could just be deleted. No functional changes. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the msm_a2m_int() function into the header, and does a small macro clean up to be more inline with Linux norms. No functional changes. Signed-off-by: Daniel Walker <dwalker@codeaurora.org>
| * | | arm: msm: smd: convert unsigned addr to unsigned longDaniel Walker2010-05-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "unsigned" translates to "unsigned int", but this value holds an address. We always want to use unsigned long for addresses since it will change size to fit the machine. This just convert the one address holder to unsigned long.

| * | | arm: msm: smd: use either package v3 or v4 not bothDaniel Walker2010-05-123-48/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This modifies SMD to use either the package v3 or package v4, but not both. The current code tries to allocate as v4 on all system which can produce a scary looking error message on boot up, smem_find(16, 40): wrong size 16424 smd_alloc_channel() cid=02 size=08192 'SMD_RPCCALL' With this error the code then falls back on the package v3 allocation method. This method is inefficient because it causes a slow down on some systems even when the allocation method can be determined at compile time. It also causes a kernel size increase that effects all system and is not needed. This change corrects the allocation to use one method or the other and not both.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Forcing the alignment prevents gcc from generating byte reads for word member variables. Lack of this caused issues when the app processor modified struct members and the modem saw a partial word write.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some smd clients may write from multiple threads, in which case it's not safe to call smd_write without holding a lock. smd_write_atomic() provides the same functionality as smd_write() but obtains the smd lock first.
