2009-12-15Blackfin: BF537: push down error masks to avoid namespace pollutionMike Frysinger1-4/+10
The error masks are only needed in the BF537 demux error code, so instead of needing all the short peripheral defines in global space, push these masks into the one file where they are actually needed. This fixes a bunch of define collisions with common code (can/serial/etc...). Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Barry Song <barry.song@analog.com>
2009-12-15Blackfin: SMP: don't start up core b until its state has been completely onlinedYi Li1-8/+8
When testing PREEMPT_RT kernel on BF561-EZKit, the kernel blocks while booting. When the kernel initializes the ethernet driver, it sleeps and never wakes up. The issue happens when the kernel waits for a timer for Core B to timeout (the timers are per-cpu based: static DEFINE_PER_CPU(struct tvec_base *, tvec_bases) = &boot_tvec_bases). However, the ksoftirqd thread for Core B (note, the ksoftirqd thread is also per-cpu based) cannot work properly, and the timers for Core B never times out. When ksoftirqd() for the first time runs on core B, it is possible core A is still initializing core B (see smp_init() -> cpu_up() -> __cpu_up()). So the "cpu_is_offline()" check may return true and ksoftirqd moves to "wait_to_die". So delay the core b start up until the per-cpu timers have been set up fully.

2009-12-15Blackfin: bf538: add support for extended GPIO banksMichael Hennerich1-0/+30
The GPIOs on ports C/D/E on the BF538/BF539 do not behave the same way as the other ports on the part and the same way as all other Blackfin parts. The MMRs are programmed slightly different and they cannot be used to generate interrupts or wakeup a sleeping system. Since these guys don't fit into the existing code, create a simple gpiolib driver for them.

2009-12-15Blackfin: cpufreq: use a constant latencyMichael Hennerich1-1/+2
PLL_LOCKCNT applies only to the PLL programming sequence which does not apply to core and system clock dividers. Writes to PLL_DIV to change the CSEL/SSEL dividers take effect immediately. There is still overhead in software in writing the new dividers, so just use a value of 50us as this should be good enough.

2009-10-12net: Introduce recvmmsg socket syscallArnaldo Carvalho de Melo1-0/+1
Meaning receive multiple messages, reducing the number of syscalls and net stack entry/exit operations. Next patches will introduce mechanisms where protocols that want to optimize this operation will provide an unlocked_recvmsg operation. This takes into account comments made by: . Paul Moore: sock_recvmsg is called only for the first datagram, sock_recvmsg_nosec is used for the rest. . Caitlin Bestler: recvmmsg now has a struct timespec timeout, that works in the same fashion as the ppoll one. If the underlying protocol returns a datagram with MSG_OOB set, this will make recvmmsg return right away with as many datagrams (+ the OOB one) it has received so far. . Rémi Denis-Courmont & Steven Whitehouse: If we receive N < vlen datagrams and then recvmsg returns an error, recvmmsg will return the successfully received datagrams, store the error and return it in the next call. This paves the way for a subsequent optimization, sk_prot->unlocked_recvmsg, where we will be able to acquire the lock only at batch start and end, not at every underlying recvmsg call.

2009-09-21perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar1-1/+1
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.

2009-09-16Blackfin: cleanup sync handling when enabling/disabling cplbsYi Li2-66/+12
The handling of updating the [DI]MEM_CONTROL MMRs does not follow proper sync procedures as laid out in the Blackfin programming manual. So rather than audit/fix every call location, create helper functions that do the right things in order to safely update these MMRs. Then convert all call sites to use these new helper functions. While we're fixing the code, drop the workaround for anomaly 05000125 as that anomaly applies to old versions of silicon that we do not support.

2009-09-16Blackfin: improve double fault debug handlingGraf Yang2-13/+17
Since the hardware only provides reporting for the last exception handled, and the values are valid only when executing the exception handler, we need to save the context for reporting at a later point. While we do this for one exception, it doesn't work properly when handling a second one as the original exception is clobbered by the double fault. So when double fault debugging is enabled, create a dedicated shadow of these values and save/restore out of there. Now the crash report properly displays the first exception as well as the second one. Signed-off-by: Graf Yang <graf.yang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-16Blackfin: catch hardware errors earlier during bootingRobin Getz1-0/+11
Allow hardware errors to be caught during early portions of booting, and leave something in the shadow console that people can use to debug their system with (to be printed out by the bootloader on next reset). This enables the hardare error interrupts in head.S, allowing us to find hardware errors when they happen (well, as much as you can with a hardware error) and prints out the trace if it is enabled. This will catch errors (like booting the wrong image on a 533) which previously resulted in a infinite loop/hang, as well as random hardware errors before before setup_arch(). To disable this debug only feature - turn off EARLY_PRINTK. Signed-off-by: Robin Getz <robin.getz@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-09-16Blackfin: use generic name for EVT14 handlerPhilippe Gerum2-5/+5
The purpose of the EVT14 handler may depend on whether CONFIG_IPIPE is enabled, albeit its implementation can be the same in both cases. When the interrupt pipeline is enabled, EVT14 can be used to raise the core priority level for the running code; when CONFIG_IPIPE is off, EVT14 can be used to lower this level before running softirq handlers. Rename evt14_softirq to evt_evt14 to pick an identifier that fits both, which allows to reuse the same vector setup code as well.

2009-09-16Blackfin: make EVT3->EVT5 lowering more robust wrt IPEND[4]Robin Getz1-32/+54
We handle many exceptions at EVT5 (hardware error level) so that we can catch exceptions in our exception handling code. Today - if the global interrupt enable bit (IPEND[4]) is set (interrupts disabled) our trap handling code goes into a infinite loop, since we need interrupts to be on to defer things to EVT5. Normal kernel code should not trigger this for any reason as IPEND[4] gets cleared early (when doing an interrupt context save) and the kernel stack there should be sane (or something much worse is happening in the system). But there have been a few times where this has happened, so this change makes sure we dump a proper crash message even when things have gone south.

2009-07-16Blackfin: drop per-cpu loops_per_jiffy trackingMichael Hennerich1-1/+1
On Blackfin SMP, a per-cpu loops_per_jiffy is pointless since both cores always run at the same CCLK. In addition, the current implementation has flaws since the main consumer for loops_per_jiffy (asm/delay.h) uses the global kernel loops_per_jiffy and not the per_cpu one.

2009-06-22Blackfin: decouple unrelated cache settings to get exact behaviorJie Zhang3-5/+5
The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware.

2009-06-13Blackfin: fix deadlock in SMP IPI handlerSonic Zhang1-6/+7
When a low priority interrupt (like ethernet) is triggered between 2 high priority IPI messages, a deadlock in disable_irq() is hit by the second IPI handler. This is because the second IPI message is queued within the first IPI handler, but the handler doesn't process all messages, and new ones are inserted rather than appended. So now we process all the pending messages, and append new ones to the pending list.

2009-06-12Blackfin: make deferred hardware errors more exactRobin Getz2-18/+68
Hardware errors on the Blackfin architecture are queued by nature of the hardware design. Things that could generate a hardware level queue up at the system interface and might not process until much later, at which point the system would send a notification back to the core. As such, it is possible for user space code to do something that would trigger a hardware error, but have it delay long enough for the process context to switch. So when the hardware error does signal, we mistakenly evaluate it as a different process or as kernel context and panic (erp!). This makes it pretty difficult to find the offending context. But wait, there is good news somewhere. By forcing a SSYNC in the interrupt entry, we force all pending queues at the system level to be processed and all hardware errors to be signaled. Then we check the current interrupt state to see if the hardware error is now signaled. If so, we re-queue the current interrupt and return thus allowing the higher priority hardware error interrupt to process properly. Since we haven't done any other context processing yet, the right context will be selected and killed. There is still the possibility that the exact offending instruction will be unknown, but at least we'll have a much better idea of where to look. The downside of course is that this causes system-wide syncs at every interrupt point which results in significant performance degradation. Since this situation should not occur in any properly configured system (as hardware errors are triggered by things like bad pointers), make it a debug configuration option and disable it by default.
