* sh: DSP save/restore ordering and a0 sign extension fixups.Paul Mundt2009-08-201-13/+13
| | | | | | | | | | | | | | | | | | | | | | As an excellent indicator of how much testing the DSP code gets, a couple of rather glaring bugs in the DSP save/restore paths were found: - In the DSP restore case a0 needs to be popped off before a0g, or the value of a0g is clobbered by the MSB of a0 in the case of sign extension. - Beyond that, the save and restore orders were out of sync, so this fixes that up as well. At the same time, we switch over to using movs.l for both the save and restore of the general DSP registers as opposed to using sts.l (which was initially put in place to work around a bug in ancient binutils versions which the kernel no longer supports).

The hardware driving the USB port is the on-chip USB0 block in the sh7724 processor configured as USB gadget controller. This board is using external hardware to detect USB hotplug events and allows the processor to dynamically start and stop clocks.

Use fixed buffers for bulk and isochronous pipes, also make sure to handle the isochronous-as-bulk case. With fixed buffers there is no need to keep track of used buffers with bi_bufnum.

* sh: Add a few missing irqflags tracing markers.Matt Fleming2009-08-182-11/+24
| | | | | | | | | | | | | | | | | | | | | save_regs contains an SR modification without an irqflags annotation, which resulted in a missing TRACE_IRQS_OFF in the interrupt exception path on SH-3/SH4. I've also moved the TRACE_IRQS_OFF/ON annotation when returning from the interrupt to just before we call __restore_all. This seems like the most logical place to put this because the annotation is for when we restore the SR register so we should delay the annotation until as last as possible. We were also missing a TRACE_IRQS_OFF in resume_kernel when CONFIG_PREEMPT is enabled. The end result is that this fixes up the lockdep engine debugging support with CONFIG_PREEMPT enabled on all SH-3/4 parts.

* sh: Add support for DWARF GNU extensionsMatt Fleming2009-08-162-1/+17
| | | | | | | | | | | | | | Also, remove the "fix" to DW_CFA_def_cfa_register where we reset the frame's cfa_offset to 0. This action is incorrect when handling DW_CFA_def_cfa_register as the DWARF spec specifically states that the previous contents of cfa_offset should be used with the new register. The reason that I thought cfa_offset should be reset to 0 was because it was being assigned a bogus value prior to executing the DW_CFA_def_cfa_register op. It turns out that the bogus cfa_offset value came from interpreting .cfi_escape pseudo-ops (those used by the GNU extensions) as CFA_DW_def_cfa ops.

* sh: Try again at getting the initial return address for an unwindMatt Fleming2009-08-161-35/+6
| | | | | | | | | | | | | | | | | | The previous hack for calculating the return address for the first frame we unwind (dwarf_unwinder_dump) didn't always work. The problem was that it assumed once it read the rule for calculating the return address, there would be no new rules for calculating it. This isn't true because the way in which the CFA is calculated can change as you progress through a function and the return address is figured out using the CFA. Therefore, the way to calculate the return address can change. So, instead of using some offset from the beginning of dwarf_unwind_stack which is just a flakey approach, and instead of executing instructions from the FDE until the return address is setup, we now figure out the pc in dwarf_unwind_stack() just before we call dwarf_cfa_execute_insns().

| * sh: use in-soc KEYSC on se7724Magnus Damm2009-08-151-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the Solution Engine 7724 board code to use in-SoC KEYSC resources for the keyboard platform device. Using the in-SoC key scan controller fixes a crash-during-resume issue. Without this patch the KEYSC hardware block located in the board specific FPGA is used together with an external IRQ which is routed through the FPGA and handled by some board specific demux code. This board specific FPGA interrupt code does not implement desc->set_wake() so the enable_irq_wake() call in the sh_keysc driver will fail at suspend-to-ram time and the disable_irq_wake() will bomb out when resuming. Changing the platform data to use the in-SoC KEYSC hardware makes the se7724 board support code less special which is a good thing. Also, the board specific KEYSC pin setup code selects in-SoC pin functions already which makes the current FPGA platform device data look like a typo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | free_irq() can remove an irqaction while the corresponding interrupt is in progress, but free_irq() sets action->thread to NULL unconditionally, which might lead to a NULL pointer dereference in handle_IRQ_event() when the hard interrupt context tries to wake up the handler thread. Prevent this by moving the thread stop after synchronize_irq(). No need to set action->thread to NULL either as action is going to be freed anyway. This fixes a boot crash reported against preempt-rt which uses the mainline irq threads code to implement full irq threading.

| | * perf tools: Add a general option to enable raw sample recordsFrederic Weisbecker2009-08-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While we can enable the perf sample records per tracepoint counter, we may also want to enable this option for every tracepoint counters to open, so that we don't need to add a :record flag for all of them. Add the -R, --raw-samples options for this purpose.

| | * perf tools: Add a per tracepoint counter attribute to get raw sampleFrederic Weisbecker2009-08-132-1/+11

In the future, we may want to support further flags, separated by commas.

| | * perf_counter: Provide hw_perf_counter_setup_online() APIsIngo Molnar2009-08-132-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide weak aliases for hw_perf_counter_setup_online(). This is used by the BTS patches (for v2.6.32), but it interacts with fixes so propagate this upstream. (it has no effect as of yet) Also export perf_counter_output() to architecture code.
