sparc32: genirq support The conversion of sparc32 to genirq is based on original work done by David S. Miller.

sparc64: sparse irq This patch attempts to do a few things. The highlights are: 1) enable SPARSE_IRQ unconditionally, 2) kills off !SPARSE_IRQ code 3) allocates ivector_table at boot time and 4) default to cookie only VIRQ mechanism for supported firmware. The first firmware with cookie only support for me appears on T5. You can optionally force the HV firmware to not cookie only mode which is the sysino support. The sysino is a deprecated HV mechanism according to the most recent SPARC Virtual Machine Specification. HV_GRP_INTR is what controls the cookie/sysino firmware versioning. The history of this interface is: 1) Major version 1.0 only supported sysino based interrupt interfaces. 2) Major version 2.0 added cookie based VIRQs, however due to the fact that OSs were using the VIRQs without negoatiating major version 2.0 (Linux and Solaris are both guilty), the VIRQs calls were allowed even with major version 1.0 To complicate things even further, the VIRQ interfaces were only actually hooked up in the hypervisor for LDC interrupt sources. VIRQ calls on other device types would result in HV_EINVAL errors. So effectively, major version 2.0 is unusable. 3) Major version 3.0 was created to signal use of VIRQs and the fact that the hypervisor has these calls hooked up for all interrupt sources, not just those for LDC devices. A new boot option is provided should cookie only HV support have issues. hvirq - this is the version for HV_GRP_INTR. This is related to HV API versioning. The code attempts major=3 first by default. The option can be used to override this default. I've tested with SPARSE_IRQ on T5-8, M7-4 and T4-X and Jalap?no. Signed-off-by: Bob Picco <bob.picco@oracle.com> Signed-off-by: David S.

perf: Do the big rename: Performance Counters -> Performance Events Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.

Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

container freezer: implement freezer cgroup subsystem This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read. The state will remain "FREEZING" until one of these things happens: 1) Userspace cancels the freezing operation by writing "RUNNING" to the freezer.state file 2) Userspace retries the freezing operation by writing "FROZEN" to the freezer.state file (writing "FREEZING" is not legal and returns EIO) 3) The tasks that blocked the cgroup from entering the "FROZEN" state disappear from the cgroup's set of tasks.

sparc: fix MSI build failure on Sparc32 Commit ebd97be635 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option') removes the ARCH_SUPPORTS_MSI Kconfig option that allowed architectures to indicate whether they support PCI MSI or not. Now, PCI MSI support can be compiled in on any architecture thanks to the use of weak functions thanks to 4287d824f265 ('PCI: use weak functions for MSI arch-specific functions'). So, architecture specific code is now responsible to ensure that its PCI MSI code builds in all cases, or be appropriately conditionally compiled. On Sparc, the MSI support is only provided for Sparc64, so the ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and not for the Sparc architecture as a whole. Therefore, removing ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y, because the Sparc-specific MSI code is not designed to be built on Sparc32. To solve this, this commit ensures that the Sparc MSI code is only built on Sparc64. This is done thanks to a new Kconfig Makefile helper option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The SPARC64_PCI_MSI option is an hidden option that is true when both Sparc64 PCI support is enabled and MSI is enabled. The arch/sparc/kernel/pci_msi.c file is now only built when SPARC64_PCI_MSI is true.

sparc: fix MSI build failure on Sparc32 Commit ebd97be635 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option') removes the ARCH_SUPPORTS_MSI Kconfig option that allowed architectures to indicate whether they support PCI MSI or not. Now, PCI MSI support can be compiled in on any architecture thanks to the use of weak functions thanks to 4287d824f265 ('PCI: use weak functions for MSI arch-specific functions'). So, architecture specific code is now responsible to ensure that its PCI MSI code builds in all cases, or be appropriately conditionally compiled. On Sparc, the MSI support is only provided for Sparc64, so the ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and not for the Sparc architecture as a whole. Therefore, removing ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y, because the Sparc-specific MSI code is not designed to be built on Sparc32. To solve this, this commit ensures that the Sparc MSI code is only built on Sparc64. This is done thanks to a new Kconfig Makefile helper option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The SPARC64_PCI_MSI option is an hidden option that is true when both Sparc64 PCI support is enabled and MSI is enabled. The arch/sparc/kernel/pci_msi.c file is now only built when SPARC64_PCI_MSI is true.
