2011-01-12ACPI, intel_idle: Cleanup idle= internal variablesThomas Renninger2-7/+4
Having four variables for the same thing: idle_halt, idle_nomwait, force_mwait and boot_option_idle_overrides is rather confusing and unnecessary complex. if idle= boot param is passed, only set up one variable: boot_option_idle_overrides Introduces following functional changes/fixes: - intel_idle driver does not register if any idle=xy boot param is passed. - processor_idle.c will also not register a cpuidle driver and get active if idle=halt is passed. Before a cpuidle driver with one (C1, halt) state got registered Now the default_idle function will be used which finally uses the same idle call to enter sleep state (safe_halt()), but without registering a whole cpuidle driver. That means idle= param will always avoid cpuidle drivers to register with one exception (same behavior as before): idle=nomwait may still register acpi_idle cpuidle driver, but C1 will not use mwait, but hlt. This can be a workaround for IO based deeper sleep states where C1 mwait causes problems.

2011-01-07fs: scale mntget/mntputNick Piggin1-1/+1
The problem that this patch aims to fix is vfsmount refcounting scalability. We need to take a reference on the vfsmount for every successful path lookup, which often go to the same mount point. The fundamental difficulty is that a "simple" reference count can never be made scalable, because any time a reference is dropped, we must check whether that was the last reference. To do that requires communication with all other CPUs that may have taken a reference count. We can make refcounts more scalable in a couple of ways, involving keeping distributed counters, and checking for the global-zero condition less frequently. - check the global sum once every interval (this will delay zero detection for some interval, so it's probably a showstopper for vfsmounts). - keep a local count and only taking the global sum when local reaches 0 (this is difficult for vfsmounts, because we can't hold preempt off for the life of a reference, so a counter would need to be per-thread or tied strongly to a particular CPU which requires more locking). - keep a local difference of increments and decrements, which allows us to sum the total difference and hence find the refcount when summing all CPUs. Then, keep a single integer "long" refcount for slow and long lasting references, and only take the global sum of local counters when the long refcount is 0. This last scheme is what I implemented here. Attached mounts and process root and working directory references are "long" references, and everything else is a short reference. This allows scalable vfsmount references during path walking over mounted subtrees and unattached (lazy umounted) mounts with processes still running in them. This results in one fewer atomic op in the fastpath: mntget is now just a per-CPU inc, rather than an atomic inc; and mntput just requires a spinlock and non-atomic decrement in the common case. However code is otherwise bigger and heavier, so single threaded performance is basically a wash. Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-07fs: dcache reduce branches in lookup pathNick Piggin1-1/+1
Reduce some branches and memory accesses in dcache lookup by adding dentry flags to indicate common d_ops are set, rather than having to check them. This saves a pointer memory access (dentry->d_op) in common path lookup situations, and saves another pointer load and branch in cases where we have d_op but not the particular operation. Patched with: git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-07fs: change d_delete semanticsNick Piggin1-1/+1
Change d_delete from a dentry deletion notification to a dentry caching advise, more like ->drop_inode. Require it to be constant and idempotent, and not take d_lock. This is how all existing filesystems use the callback anyway. This makes fine grained dentry locking of dput and dentry lru scanning much simpler. Signed-off-by: Nick Piggin <npiggin@kernel.dk>
2011-01-07ACPI: Use ioremap_cache()Len Brown1-0/+5
Although the temporary boot-time ACPI table mappings were set up with CPU caching enabled, the permanent table mappings and AML run-time region memory accesses were set up with ioremap(), which on x86 is a synonym for ioremap_nocache(). Changing this to ioremap_cache() improves performance as seen when accessing the tables via acpidump, or /sys/firmware/acpi/tables. It should also improve AML run-time performance. No change on ia64.

2010-11-16SCSI host lock push-downJeff Garzik1-1/+3
Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

2010-10-24KVM: ia64: define kvm_lapic_enabled() to fix a compile errorTakuya Yoshikawa1-0/+1
The following patch commit 57ce1659316f4ca298919649f9b1b55862ac3826 KVM: x86: In DM_LOWEST, only deliver interrupts to vcpus with enabled LAPIC's ignored the fact that kvm_irq_delivery_to_apic() was also used by ia64. We define kvm_lapic_enabled() to fix a compile error caused by this. This will have the same effect as reverting the problematic patch for ia64.

2010-10-22ioctl: Use asm-generic/ioctls.h on ia64 (enables termiox)Jeff Mahoney1-88/+1
This patch converts ia64 to use asm-generic/ioctls.h instead of its own version. The differences between the arch-specific version and the generic version are as follows: - The generic version adds TIOCSRS485 and TIOCGRS485, which are unused by any driver available on this architecture. - The generic version adds support for termiox Cc: Tony Luck <tony.luck@intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
