* ramoops: make record_size a module parameterSergiu Iordache2011-07-261-10/+27
| | | | | | | | | | | | | | | The size of the dump is currently set using the RECORD_SIZE macro which is set to a page size. This patch makes the record size a module parameter and allows it to be set through platform data as well to allow larger dumps if needed.

| | | | | | | | | | | | | | | | The platform driver currently allows setting the mem_size and mem_address. ince dump_oops is also a module parameter it would be more consistent if it could be set through platform data as well.

* ramoops: use module parameters instead of platform data if not availableMarco Stornelli2011-07-261-12/+35
| | | | | | | | | | | | | | | | Use generic module parameters instead of platform data, if platform data are not available.

* rtc: fix hrtimer deadlockThomas Gleixner2011-07-261-19/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | Ben reported a lockup related to rtc. The lockup happens due to: CPU0 CPU1 rtc_irq_set_state() __run_hrtimer() spin_lock_irqsave(&rtc->irq_task_lock) rtc_handle_legacy_irq(); spin_lock(&rtc->irq_task_lock); hrtimer_cancel() while (callback_running); So the running callback never finishes as it's blocked on rtc->irq_task_lock. Use hrtimer_try_to_cancel() instead and drop rtc->irq_task_lock while waiting for the callback. Fix this for both rtc_irq_set_state() and rtc_irq_set_freq().

To get this guarantee, we need to perform an MMIO read from the device, which will flush all outstanding DMAs from bridges between the device and the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The writeback ring pointer and IH ring pointer are read using le32_to_cpu so we do not want the chip to byteswap them on big-endian. We still want to byteswap the ring itself and the IBs, so we don't touch that but we remove setting of the byteswap bits in CP_RB_RPTR_ADDR and IH_CNTL. In general, for things like that where we control all the accessors easily, we are better off doing the swap in SW rather than HW. Paradoxally, it does keep the code closer to x86 and avoid using poorly tested HW features. I also changed the use of RADEON_ to R600_ in a couple of cases to be more consistent with the surrounding code.

They also allow to limit these flags to specific outputs. Both things were previously undocumented. Also the parsing of the line had some oddities: -A lot of misplaced options were silently ignored or partly rejected instead of stopping the parsing immediately -The 'R' option is documented to follow the 'M' option if specified. It is not documented that 'M' is needed to specify 'R' (also this is the case for normal fb drivers). In fact the code is correct for normal fb drivers but wrong for DRM ones. The old code allowed 'R' only _before_ 'M' (since it parses backwards) and only if 'M' is given at all which is not needed for the DRM drivers. -the margins option ('m') was parsed but later ignored even if the later functions support it. -specifying multiple enable options at the same time did not lead to an error. -specifying something bogus for horizontal resolution (i.e. other things as digits) did not lead to an error but an invalid resolution was used. If any errors are encountered the position of the faulting string is now printed to the user and the complete mode is ignored. This gives much more consistent error behaviour. I also removed some useless assignments and changed the local flag variables to be bool. Signed-off-by: Rolf Eike Beer <eike-kernel@sf-tec.de> Signed-off-by: Dave Airlie <airlied@redhat.com>

This allocation is roughly 200 bytes, a little too large to friviously place on the stack. However, we can simply use the few bytes we need stored within the original DVO timing data, skip the translation and do the compare directly between the timing data rather than on a mode, thus avoiding the need for any temporary allocations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The read back of the available FIFO entries is vital for system stability, but extremely costly. However, we only need a guide so as to avoid eating into the reserved entries and since we are the only consumer we can cache the read of the count from the last write.
