| * [IA64] Fix ISA IRQ trigger model and polarity settingLiu Jiang2012-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling Interrupt Source Override in MADT table, the default ISA IRQ trigger model and polarity should be edge-rising. Current IA64 implmentation doesn't follow the specification and set default ISA IRQ trigger model as level-low. With that wrong configuration and when system runs out of interrupt vectors, it will cause vector sharing among edge triggered ISA IRQ and level triggered PCI IRQ, then interrupt storm. So change the code to follow the specification. Signed-off-by: Liu Jiang <jiang.liu@huawei.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [IA64] simserial, bail out when request_irq failsJiri Slaby2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | Without this, the code succeeds when the port is opened by root and we get unwanted interrupts storm on the first key stroke. Instead of that, tell the user we failed and that we won't continue. I suppose, the code was copied from the serial layer where we may want to change the irq number, so we must allow open even of the failing port. This is not the case for this driver at all.

| * [IA64] hpsim, initialize chip for assigned irqsJiri Slaby2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when assign_irq_vector is called and the irq connected in the simulator, the irq is not ready. request_irq will return ENOSYS immediately. It is because the irq chip is unset. Hence set the chip properly to irq_type_hp_sim. And make sure this is done from both users of simulated interrupts. Also we have to set handler here, otherwise we end up in handle_bad_int resulting in spam in logs and no irqs handled. We use handle_simple_irq as these are SW interrupts that need no ACK or anything. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [IA64] hpsim, fix SAL handling in fw-emuJiri Slaby2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The switch-cases of SAL_FREQ_BASE generate non-relocatable code. The same as for the ifs one level upper. This causes oopses early in boot because the kernel jumps to the hell instead of the offset in sal callback. So use ifs here for SAL_FREQ_BASE decision too. Isn't there any compiler directive or settings to solve that cleanly? Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>

| * [IA64] disable interrupts when exiting from ia64_mca_cmc_int_handler()Jiri Kosina2012-02-08
| | | | | | | | | | | | | | | | | | | | | | | | | | SAL specification mandates that ia64_mca_log_sal_error_record() gets called with interrupts enabled, and that's why ia64_mca_cmc_int_handler() is enabling them. It however forgets to re-disable them when exiting, which triggers WARN_ON() in generic IRQ handler. Disable the interrupts again before exiting. This is analogous to a3967685745 ("[IA64] disable interrupts at end of ia64_mca_cpe_int_handler()"). Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Tony Luck <tony.luck@intel.com>

There's also a new initcall_debug feature from Arjan which will print out quirk timing information to help identify slow quirks for fixing or refinement (Yinghai sent in a few patches to do just that once the new debug code landed). Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas. He's been a core PCI and Linux contributor for some time now, and has kindly volunteered to take over. I just don't feel I have the time for PCI review and work that it deserves lately (I've taken on some other projects), and haven't been as responsive lately as I'd like, so I approached Bjorn asking if he'd like to manage things. He's going to give it a try, and I'm confident he'll do at least as well as I have in keeping the tree managed, patches flowing, and keeping things stable."

It also inhibits cpufreq scaling drivers to load so that only the hypervisor can make power management decisions - fixing a weird perf bug. There is one thing in the Kconfig that you won't like: "default y if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by default is off). I've a fix to convert that boolean expression into "default m" which I am going to post after the cpufreq git pull - as the two patches to make this work depend on a fix in Dave Jones's tree. - Function Level Reset (FLR) support in the Xen PCI backend.

| * | xen/enlighten: Expose MWAIT and MWAIT_LEAF if hypervisor OKs it.Konrad Rzeszutek Wilk2012-03-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For the hypervisor to take advantage of the MWAIT support it needs to extract from the ACPI _CST the register address. But the hypervisor does not have the support to parse DSDT so it relies on the initial domain (dom0) to parse the ACPI Power Management information and push it up to the hypervisor. The pushing of the data is done by the processor_harveset_xen module which parses the information that the ACPI parser has graciously exposed in 'struct acpi_processor'. For the ACPI parser to also expose the Cx states for MWAIT, we need to expose the MWAIT capability (leaf 1). Furthermore we also need to expose the MWAIT_LEAF capability (leaf 5) for cstate.c to properly function. The hypervisor could expose these flags when it traps the XEN_EMULATE_PREFIX operations, but it can't do it since it needs to be backwards compatible. Instead we choose to use the native CPUID to figure out if the MWAIT capability exists and use the XEN_SET_PDC query hypercall to figure out if the hypervisor wants us to expose the MWAIT_LEAF capability or not. Note: The XEN_SET_PDC query was implemented in c/s 23783: "ACPI: add _PDC input override mechanism". With this in place, instead of C3 ACPI IOPORT 415 we get now C3:ACPI FFH INTEL MWAIT 0x20 Note: The cpu_idle which would be calling the mwait variants for idling never gets set b/c we set the default pm_idle to be the hypercall variant.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So now we convert startup to be ->activate of tty_port. This means we no longer care about INITIALIZED and TTY_IO_ERROR flags. After we have ->activate much of the code may go as it duplicates what tty_port_open does. In this case tty_port_open adds block_til_ready to the path. But we do not define carrier hooks, so it is a noop.

The ISR was never written for that kind of stuff. So remove all that crap with a hash of linked lists and pass the pointer directly to the ISR. BTW this answers the question there: * I don't know exactly why they don't use the dev_id opaque data * pointer instead of this extra lookup table -> Because they thought they will support more devices bound to a single interrupt w/o IRQF_SHARED. They would need exactly the hash there. What I don't understand is rebinding of the interrupt in the shutdown path. They perhaps meant to do just synchronize_irq? In any case, this is all gone and free_irq there properly. By removing the hash we save some bits (exactly NR_IRQS * 8 bytes of .bss and over a kilo of .text): before: text data bss dec hex filename 19600 320 8227 28147 6df3 ../a/ia64/arch/ia64/hp/sim/simserial.o after: text data bss dec hex filename 18568 320 28 18916 49e4 ../a/ia64/arch/ia64/hp/sim/simserial.o Note that a shared interrupt could not work too. request_irq requires data parameter to be non-NULL. So the whole IRQ_T exercise was pointless. Finally, this helps us remove another two members of async_struct :).
