2011-08-06oom_ajd: don't use WARN_ONCE, just use printk_onceLinus Torvalds1-1/+1
WARN_ONCE() is very annoying, in that it shows the stack trace that we don't care about at all, and also triggers various user-level "kernel oopsed" logic that we really don't care about. And it's not like the user can do anything about the applications (sshd) in question, it's a distro issue.

2011-08-06lib/sha1: use the git implementation of SHA-1Mandeep Singh Baines2-55/+159
For ChromiumOS, we use SHA-1 to verify the integrity of the root filesystem. The speed of the kernel sha-1 implementation has a major impact on our boot performance. To improve boot performance, we investigated using the heavily optimized sha-1 implementation used in git. With the git sha-1 implementation, we see a 11.7% improvement in boot time. 10 reboots, remove slowest/fastest. Before: Mean: 6.58 seconds Stdev: 0.14 After (with git sha-1, this patch): Mean: 5.89 seconds Stdev: 0.07 The other cool thing about the git SHA-1 implementation is that it only needs 64 bytes of stack for the workspace while the original kernel implementation needed 320 bytes.

2011-08-05jump label: Reduce the cycle count by changing the link orderJason Baron1-1/+2
In the course of testing jump labels for use with the CFS bandwidth controller, Paul Turner, discovered that using jump labels reduced the branch count and the instruction count, but did not reduce the cycle count or wall time. I noticed that having the jump_label.o included in the kernel but not used in any way still caused this increase in cycle count and wall time. Thus, I moved jump_label.o in the kernel/Makefile, thus changing the link order, and presumably moving it out of hot icache areas. This brought down the cycle count/time as expected. In addition to Paul's testing, I've tested the patch using a single 'static_branch()' in the getppid() path, and basically running tight loops of calls to getppid(). Here are my results for the branch disabled case: With jump labels turned on (CONFIG_JUMP_LABEL), branch disabled: Performance counter stats for 'bash -c /tmp/getppid;true' (50 runs): 3,969,510,217 instructions # 0.864 IPC ( +-0.000% ) 4,592,334,954 cycles ( +- 0.046% ) 751,634,470 branches ( +- 0.000% ) 1.722635797 seconds time elapsed ( +- 0.046% ) Jump labels turned off (CONFIG_JUMP_LABEL not set), branch disabled: Performance counter stats for 'bash -c /tmp/getppid;true' (50 runs): 4,009,611,846 instructions # 0.867 IPC ( +-0.000% ) 4,622,210,580 cycles ( +- 0.012% ) 771,662,904 branches ( +- 0.000% ) 1.734341454 seconds time elapsed ( +- 0.022% ) Signed-off-by: Jason Baron <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ingo Molnar <[email protected]> Tested-by: Paul Turner <[email protected]>
2011-08-05PM / Runtime: Allow _put_sync() from interrupts-disabled contextKevin Hilman2-7/+13
Currently the use of pm_runtime_put_sync() is not safe from interrupts-disabled context because rpm_idle() will release the spinlock and enable interrupts for the idle callbacks. This enables interrupts during a time where interrupts were expected to be disabled, and can have strange side effects on drivers that expected interrupts to be disabled. This is not a bug since the documentation clearly states that only _put_sync_suspend() is safe in IRQ-safe mode. However, pm_runtime_put_sync() could be made safe when in IRQ-safe mode by releasing the spinlock but not re-enabling interrupts, which is what this patch aims to do. Problem was found when using some buggy drivers that set pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled context.

2011-08-05OMAP2+: PM: SmartReflex: use put_sync_suspend for IRQ-safe disablingColin Cross1-1/+1
omap_sr_disable_reset_volt is called with irqs off in omapx_enter_sleep, as part of idle sequence, this eventually calls sr_disable and pm_runtime_put_sync. pm_runtime_put_sync calls rpm_idle, which will enable interrupts in order to call the callback. In this short interval when interrupts are enabled, scenarios such as the following can occur: while interrupts are enabled, the timer interrupt that is supposed to wake the device out of idle occurs and is acked, so when the CPU finally goes to off, the timer is already gone, missing a wakeup event. Further, as the documentation for runtime states:" However, subsystems can use the pm_runtime_irq_safe() helper function to tell the PM core that a device's ->runtime_suspend() and ->runtime_resume() callbacks should be invoked in atomic context with interrupts disabled (->runtime_idle() is still invoked the default way)." Hence, replace pm_runtime_put_sync with pm_runtime_put_sync_suspend to invoke the suspend handler and shut off the fclk for SmartReflex module instead of using the idle handler in interrupt disabled context.

2011-08-05OMAP3+: SR: ensure pm-runtime callbacks can be invoked with IRQs disabledNishanth Menon1-0/+1
SmartReflex should be disabled while entering low power mode due to a) SmartReflex values are not defined for retention voltage, further b) with SmartReflex enabled, if CPU enters lower c-states, FSM will try to bump the voltage to current OPP's voltage for which it has entered c-state; hence SmartReflex needs to be disabled for MPU, CORE and IVA voltage domains in idle path before enabling auto retention voltage achievement on the device. However, since the current pm_runtime setup for SmartReflex devices are setup to allow callbacks to be invoked with interrupts enabled, calling SmartReflex enable/disable from other contexts such as idle paths where preemption is disabled causes warnings such as the following indicating of a potential race.
