2009-12-01powerpc: Fix DEBUG_HIGHMEM build break from d4515646699Becky Bruce1-0/+11
Code was added to mm/higmem.c that depends on several kmap types that powerpc does not support. We add dummy invalid definitions for KM_NMI, KM_NM_PTE, and KM_IRQ_PTE. According to list discussion, this fix should not be needed anymore starting with 2.6.33. The code is commented to this effect so hopefully we will remember to remove this.

2009-11-05powerpc/85xx: sbc8548 - fixup of PCI-e related DTS fieldsPaul Gortmaker1-9/+8
The PCI-e addressing was originally patterned of the MPC8548CDS which has PCI1, PCI2, and PCI-e. Since this board only has PCI1 and PCI-e, it makes more sense to be similar to the MPC8568MDS board. This does that by cutting the PCI/PCI-e I/O sizes from 16MB to 8MB and pulling the PCI-e I/O range back to 0xe280_0000 (the hole where PCI2 I/O would have been). This also fixes a typo where an extra zero made an 8MB range a 128MB range, removes the hole left by PCI2 from the aliases, and sets the clocks to match the oscillators that are actually on the board. With accompanying u-boot updates, PCI-e has been validated with both a sky2 card (1148:9e00) and an e1000 card (8086:108b).

2009-10-28powerpc: Disable HCALL_STATS by defaultAnton Blanchard1-1/+1
The overhead of HCALL_STATS is quite high and the functionality is very rarely used. Key statistics are also missing (eg min/max). With the new hcall tracepoints much more powerful tracing can be done in a kernel module. Lets disable this by default.

2009-10-28powerpc: tracing: Give hypervisor call tracepoints access to argumentsAnton Blanchard4-20/+34
While most users of the hcall tracepoints will only want the opcode and return code, some will want all the arguments.

2009-10-28powerpc: tracing: Add hypervisor call tracepointsAnton Blanchard6-44/+175
Add hcall_entry and hcall_exit tracepoints. This replaces the inline assembly HCALL_STATS code and converts it to use the new tracepoints. To keep the disabled case as quick as possible, we embed a status word in the TOC so we can get at it with a single load. By doing so we keep the overhead at a minimum. Time taken for a null hcall: No tracepoint code: 135.79 cycles Disabled tracepoints: 137.95 cycles For reference, before this patch enabling HCALL_STATS resulted in a null hcall of 201.44 cycles!

2009-10-28powerpc: tracing: Add powerpc tracepoints for timer entry and exitAnton Blanchard2-0/+40
We can monitor the effectiveness of our power management of both the kernel and hypervisor by probing the timer interrupt. For example, on this box we see 10.37s timer interrupts on an idle core: <idle>-0 [010] 3900.671297: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3900.671302: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3911.042963: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3911.042968: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3921.414630: timer_interrupt_entry: pt_regs=c0000000ce1e7b10 <idle>-0 [010] 3921.414635: timer_interrupt_exit: pt_regs=c0000000ce1e7b10 Since we have a 207MHz decrementer it will go negative and fire every 10.37s even if Linux is completely idle.

2009-10-28powerpc: tracing: Add powerpc tracepoints for interrupt entry and exitAnton Blanchard2-0/+59
This adds powerpc-specific tracepoints for interrupt entry and exit. While we already have generic irq_handler_entry and irq_handler_exit tracepoints there are cases on our virtualised powerpc machines where an interrupt is presented to the OS, but subsequently handled by the hypervisor. This means no OS interrupt handler is invoked. Here is an example on a POWER6 machine with the patch below applied: <idle>-0 [006] 3243.949840744: irq_entry: pt_regs=c0000000ce31fb10 <idle>-0 [006] 3243.949850520: irq_exit: pt_regs=c0000000ce31fb10 <idle>-0 [007] 3243.950218208: irq_entry: pt_regs=c0000000ce323b10 <idle>-0 [007] 3243.950224080: irq_exit: pt_regs=c0000000ce323b10 <idle>-0 [000] 3244.021879320: irq_entry: pt_regs=c000000000a63aa0 <idle>-0 [000] 3244.021883616: irq_handler_entry: irq=87 handler=eth0 <idle>-0 [000] 3244.021887328: irq_handler_exit: irq=87 return=handled <idle>-0 [000] 3244.021897408: irq_exit: pt_regs=c000000000a63aa0 Here we see two phantom interrupts (no handler was invoked), followed by a real interrupt for eth0. Without the tracepoints in this patch we would have missed the phantom interrupts.

2009-10-27powerpc/ppc64: Use preempt_schedule_irq instead of preempt_scheduleBenjamin Herrenschmidt1-20/+21
Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com> Use preempt_schedule_irq to prevent infinite irq-entry and eventual stack overflow problems with fast-paced IRQ sources. This kind of problems has been observed on the PASemi Electra IDE controller. We have to make sure we are soft-disabled before calling preempt_schedule_irq and hard disable interrupts after that to avoid unrecoverable exceptions. This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered and has to be restored in both cases.
