* [ARM] 4781/1: S3C24XX: DMA suspend and resume supportBen Dooks2008-01-281-1/+25
| | | | | | | | | | | | If an DMA channel was active at suspend, then ensure that it is correctly reconfigured when the system resumes. Note, the previous policy was for each driver to handle their own reconfiguration on resume. The policy has been changed to make the individual driver's job easier.

* [ARM] 4780/1: S3C2412: Allow for seperate DMA channels for TX and RXBen Dooks2008-01-282-6/+49
| | | | | | | | | | | | The current S3C24XX DMA code does not allow for an peripheral that has one channel for RX and another for TX. This patch adds a per-cpu dma operation to select the transmit or receive channel, and adds support to the S3C2412 for the seperate DMA channels for TX and RX.

| | | | | | | | | | | | | Check if the sleep command returns due to a pending interrupt in the standby unit. If this happens, try and ack the IRQ before re-trying the resume. It is currently unclear whether the resume can be backed out of at this stage as this could cause a problem with level based interrupts.

| | | | | | | | | | | | | | | | | | | Commit 09cadedbdc01f1a4bea1f427d4fb4642eaa19da9 ("Combine instrumentation menus in kernel/Kconfig.instrumentation") broke ARM profiling support, since ARM has some extra Kconfig options and doesn't just use the common OPROFILE/KPROBES config options. Rather than just revert the thing outright, or add ARM-specific knowledge to the generic Kconfig.instrumentation file (where the only and whole point was to be generic, not too architecture-specific), this just makes ARM not use the generic version, since it doesn't suit it. So create an arm-specific version of Kconfig.instrumentation instead, and use that.

It however can produce spurious false negative if a processor exception occurs in the middle of the operation. Normally this is not a problem since cmpxchg is typically called in a loop until it succeeds to implement an atomic increment for example. Some use cases which don't involve a loop require that the operation be 100% reliable though. This patch changes the implementation so to reattempt the operation after an exception has occurred in the critical section rather than abort it. Here's a simple program to test the fix (don't use CONFIG_NO_HZ in your kernel as this depends on a sufficiently high interrupt rate): #include <stdio.h> typedef int (__kernel_cmpxchg_t)(int oldval, int newval, int *ptr); #define __kernel_cmpxchg (*(__kernel_cmpxchg_t *)0xffff0fc0) int main() { int i, x = 0; for (i = 0; i < 100000000; i++) { int v = x; if (__kernel_cmpxchg(v, v+1, &x)) printf("failed at %d: %d vs %d\n", i, v, x); } printf("done with %d vs %d\n", i, x); return 0; } Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One-shot timer mode on PXA has various bugs which prevent kernels build with NO_HZ enabled booting. They end up spinning on a permanently asserted timer interrupt because we don't properly clear it down - clearing the OIER bit does not stop the pending interrupt status. Fix this in the set_mode handler as well. Moreover, the code which sets the next expiry point may race with the hardware, and we might not set the match register sufficiently in the future. If we encounter that situation, return -ETIME so the generic time code retries.
