Convert the irq_chip functions and install handle_simple_irq for each interrupt. This converts V10 to the flow handling and lets us remove __do_IRQ(). Signed-off-by: Thomas Gleixner <[email protected]> Cc: Mikael Starvik <[email protected]>

2011-01-21h8300: Use generic irq KconfigThomas Gleixner2-5/+3
Switch to the generic irq Kconfig. h8300 has all irq chips converted to the new functions, so select the GENERIC_HARDIRQS_NO_DEPRECATED switch as well.

2011-01-21h8300: Convert interrupt handling to flow handlerThomas Gleixner1-12/+3
__do_IRQ is deprecated so h8300 needs to be converted to proper flow handling. The irq chip is simple and does not required any mask/ack/eoi functions, so we can use handle_simple_irq.

2011-01-21powerpc: Enable 64kB pages and 1024 threads in pseries configAnton Blanchard1-1/+3
- Enable 64kB pages so it gets some regular testing. - The largest POWER7 has 1024 threads so bump NR_CPUS it to match. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc: Disable mcount tracers in pseries defconfigAnton Blanchard1-2/+0
IRQSOFF_TRACER and STACK_TRACER force the kernel to be built with -pg which is a substantial overhead. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc/boot/dts: Install dts from the right directoryBen Hutchings1-1/+1
The dts-installed variable is initialised using a wildcard path that will be expanded relative to the build directory.

2011-01-21powerpc: machine_check_generic is wrong on 64bitAnton Blanchard1-23/+0
Decoding machine checks is CPU specific and so machine_check_generic doesn't do the right thing on 64bit chips. Luckily we never call into this code because we call ppc_md.machine_check_exception instead if available. Since we check cur_cpu_spec->machine_check before calling it, we may as well remove machine_check_generic from 64bit archs.

2011-01-21powerpc: Check RTAS extended log flag before checking lengthAnton Blanchard1-1/+1
The spec suggests we should first check the extended log flag before checking the length field. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc: Fix corruption when grabbing FWNMI dataAnton Blanchard1-14/+38
The FWNMI code uses a global buffer without any locks to read the RTAS error information. If two CPUs take a machine check at once then we will corrupt this buffer. Since most FWNMI rtas messages are not of the extended type, we can create a 64bit percpu buffer and use it where possible. If we do receive an extended RTAS log then we fall back to the old behaviour of using the global buffer.

2011-01-21powerpc: Rework pseries machine check handlerAnton Blanchard1-18/+30
Rework pseries machine check handler: - If MSR_RI isn't set, we cannot recover even if the machine check was fully recovered - Rename nonfatal to recovered - Handle RTAS_DISP_LIMITED_RECOVERY - Use BUS_MCEERR_AR instead of BUS_ADRERR - Don't check all the RTAS error log fields when receiving a synchronous machine check. Recent versions of the pseries firmware do not fill them in during a machine check and instead send a follow up error log with the detailed information. If we see a synchronous machine check, and we came from userspace then kill the task. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc: Don't silently handle machine checks from userspaceAnton Blanchard1-5/+0
If a machine check comes from userspace we send a SIGBUS to the task and fail to printk anything. If we are taking machine checks due to bad hardware we want to know about it right away. Furthermore if we don't complain loudly then it will look a lot like a bug in the userspace application, potentially causing a lot of confusion.

2011-01-21powerpc: Remove duplicate debugger hook in machine_check_exceptionAnton Blanchard1-2/+0

2011-01-21powerpc: Never halt RTAS error logging after receiving an unrecoverable ↵Anton Blanchard1-1/+1
machine check Newer versions of the System p firwmare send a partial RTAS error log in the machine check handler with a more detailed response appearing sometime later via check event. This means at machine check time we do not have enough information to ascertain exactly what went on. Furthermore, I have found the RTAS error logs in the machine check handler contain no useful information, so halting on them makes little sense. If we want to halt it would make more sense to do it following the error log received sometime later via check event. In light of this, never halt the error log in the pseries machine check handler.

2011-01-21powerpc: Don't force MSR_RI in machine_check_exceptionAnton Blanchard1-4/+1
We should never force MSR_RI on. If we take a machine check with MSR_RI off then we have no chance of recovering safely. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc: Print 32 bits of DSISR in show_regsAnton Blanchard1-1/+1

2011-01-21powerpc/kdump: Disable ftrace during kexecAnton Blanchard1-0/+7
We should disable ftrace during kexec, some of the tracers are very invasive and we do not want them going off while doing the low level work of swapping one kernel out for another. This mirrors what we do on x86. Even though we cannot return from a kexec on powerpc (since we do not implement CONFIG_KEXEC_JUMP), add the restore code in case we do one day.

2011-01-21powerpc/kdump: Move crash_kexec_stop_spus to kdump crash handlerAnton Blanchard3-78/+72
Use the crash handler hooks to run the SPU stop code, just like we do for ehea and cell RAS code. While I'm here I noticed "CPUSs reliabally" so fix the spelling MISTAKESs reliabally. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc/kexec: Remove empty ppc_md.machine_kexec_prepareAnton Blanchard2-22/+0
We check for a valid handler before calling ppc_md.machine_kexec_prepare so we can just remove these empty handlers. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
2011-01-21powerpc/kexec: Don't initialise kexec hooks to default handlersAnton Blanchard2-13/+0
There's no need to initialise ppc_md.machine_kexec and ppc_md.machine_kexec_prepare to the default handlers. Signed-off-by: Anton Blanchard <[email protected]> Signed-off-by: Benjamin Herrenschmidt <[email protected]>
