2009-10-09sh: Don't allocate smaller sized mappings on every iterationMatt Fleming
Currently, we've got the less than ideal situation where if we need to allocate a 256MB mapping we'll allocate four entries like so, entry 1: 128MB entry 2: 64MB entry 3: 16MB entry 4: 16MB This is because as we execute the loop in pmb_remap() we will progressively try mapping the remaining address space with smaller and smaller sizes. This isn't good because the size we use on one iteration may be the perfect size to use on the next iteration, for instance when the initial size is divisible by one of the PMB mapping sizes. With this patch, we now only need two entries in the PMB to map 256MB of address space, entry 1: 128MB entry 2: 128MB Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-10-08x86, timers: Check for pending timers after (device) interruptsArjan van de Ven
Now that range timers and deferred timers are common, I found a problem with these using the "perf timechart" tool. Frans Pop also reported high scheduler latencies via LatencyTop, when using iwlagn. It turns out that on x86, these two 'opportunistic' timers only get checked when another "real" timer happens. These opportunistic timers have the objective to save power by hitchhiking on other wakeups, as to avoid CPU wakeups by themselves as much as possible. The change in this patch runs this check not only at timer interrupts, but at all (device) interrupts. The effect is that: 1) the deferred timers/range timers get delayed less 2) the range timers cause less wakeups by themselves because the percentage of hitchhiking on existing wakeup events goes up. I've verified the working of the patch using "perf timechart", the original exposed bug is gone with this patch. Frans also reported success - the latencies are now down in the expected ~10 msec range.

Some architectures such as Sparc, ARM and MIPS (basically everything with flush_dcache_page()) need to deal with dcache aliases by carefully placing pages in both kernel and user maps. These architectures typically have to use vmalloc_user() for this. However, on other architectures, vmalloc() is not needed and has the downsides of being more restricted and slower than regular allocations.

Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added support for omap850. However, the patch accidentally removed the wrong ifdef: # define cpu_is_omap730() 1 # endif #endif +#else +# if defined(CONFIG_ARCH_OMAP850) +# undef cpu_is_omap850 +# define cpu_is_omap850() 1 +# endif +#endif ... void omap2_check_revision(void); #endif /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */ - -#endif Instead of removing removing the #endif at the end of the file, the #endif before #else should have been removed. But we cannot have multiple #else statements as pointed out by Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to: - remove the non-multi-omap special handling, as we need to detect between omap730 and omap850 anyways. - add the missing #endif back to the end of the file Reported-by: Sanjeev Premi <premi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-10-05OMAP3: PM: introduce a new powerdomain walk helperArtem Bityutskiy
The 'pwrdm_for_each()' function walks powerdomains with a spinlock locked, so the the callbacks cannot do anything which may sleep. This patch introduces a 'pwrdm_for_each_nolock()' helper which does the same, but without the spinlock locked.

2009-10-05OMAP3: PM: Enable GPIO module-level wakeupsKevin Hilman
Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are enabled as wakups. This patch also enables GPIOs in the PER powerdomain (banks 2-6) to be used as possible wakeup sources. In addition, this patch ensures that all GPIO wakeups can wakeup the MPU using the PM_MPUGRPSEL_<pwrdm> registers. NOTE: this doesn't enable the individual GPIOs as wakeups, this simply enables the per-bank wakeups at the powerdomain level. This problem was discovered by Mike Chan when preventing the CORE powerdomain from going into retention/off. When CORE was allowed to hit retention, GPIO wakeups via IO pad were working fine, but when CORE remained on, GPIO module-level wakeups were not working properly. To test, prevent CORE from going inactive/retention/off, thus preventing the IO chain from being armed: # echo 3 > /debug/pm_debug/core_pwrdm/suspend This ensures that GPIO wakeups happen via module-level wakeups and not via IO pad. Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP) Tested on Zoom2 using the QUART interrup GPIO (gpio 102, in PER) Also, c.f.

Since we don't handle any other types of PRCM interrupts right now, warn if we get any other type of PRCM interrupt.

2009-10-05OMAP3: PM: Prevent hang in prcm_interrupt_handlerJon Hunter
There are two scenarios where a race condition could result in a hang in the prcm_interrupt handler. These are: 1). Waiting for PRM_IRQSTATUS_MPU register to clear. Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event is pending for the MPU. This bit can only be cleared if the all the wake-up events latched in the various PM_WKST_x registers have been cleared. If a wake-up event occurred during the processing of the prcm interrupt handler, after the corresponding PM_WKST_x register was checked but before the PRM_IRQSTATUS_MPU was cleared, then the CPU would be stuck forever waiting for bit 0 in PRM_IRQSTATUS_MPU to be cleared. 2). Waiting for the PM_WKST_x register to clear. Some power domains have more than one wake-up source. The PM_WKST_x registers indicate the source of a wake-up event and need to be cleared after a wake-up event occurs. When the PM_WKST_x registers are read and before they are cleared, it is possible that another wake-up event could occur causing another bit to be set in one of the PM_WKST_x registers. If this did occur after reading a PM_WKST_x register then the CPU would miss this event and get stuck forever in a loop waiting for that PM_WKST_x register to clear. This patch address the above race conditions that would result in a hang.

2009-10-04m32r: Fix IPI function calls for SMPToshihiro HANAWA
This patch fixes the m32r SMP kernel after 2.6.27. A part of the following patch breaks m32r SMP operation. > m32r: convert to generic helpers for IPI function calls > commit 7b7426c8a615cf61df9a77b9df7d5b75d91e3fa0 In the above patch, a CALL_FUNC_SINGLE_IPI was newly introduced, but the its IPI vector number was wrong in the patch code. The m32r SMP kernel hanged-up during boot operation, because the CPU_BOOT_IPI was called instead of CALL_FUNC_SINGLE_IPI (CPU_BOOT_IPI had no side effect at that time because the 2nd core had already been started up), as a result, csd_unlock() was not called, then a dead lock occurred in csd_lock_wait() after the detection of Compact Flash memory as IDE generic disk.

2009-10-04m32r: Fix set_memory() for DISCONTIGMEMHirokazu Takata
In case CONFIG_DISCONTIGMEM is set, the memory size of system was always determined by CONFIG_MEMORY_SIZE and was not changeable. This patch fixes set_memory() of arch/m32r/mm/discontig.c so that we can specify memory size by the "mem=<size>" kernel parameter. Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
2009-10-04m32r: add rtc_lock variableHirokazu Takata
Add a spinlock variable "rtc_lock". This is taken from arch/arm/kernel/time.c. Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
2009-10-04m32r: define ioread* and iowrite* macrosHirokazu Takata
Define ioread* and iowrite* macros to fix the following build errors: CC [M] drivers/uio/uio_smx.o drivers/uio/uio_smx.c: In function 'smx_handler': drivers/uio/uio_smx.c:31: error: implicit declaration of function 'ioread32' drivers/uio/uio_smx.c:37: error: implicit declaration of function 'iowrite32' Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
2009-10-04m32r: export delay loop symbolsHirokazu Takata
- Move EXPORT_SYMBOL lines of delay loop functions from arch/m32r/kernel/m32r_ksyms.c to arch/m32r/lib/delay.c. - Export __ndelay. Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
2009-10-04m32r: fix tme_handlerHirokazu Takata
Fix pmd_bad check code of tme_handler (TLB Miss Exception handler). The correct _KERNPG_TABLE value is not 0x263(=611) but 0x163. Signed-off-by: Hirokazu Takata <takata@linux-m32r.org>
