If you say Y here, you are able to get PAL (Processor Abstraction
|
|
|
|
Layer) information in /proc/pal. This contains useful information
|
|
|
|
about the processors in your systems, such as cache and TLB sizes
|
|
|
|
and the PAL firmware version in use.
|
|
|
|
|
|
|
|
To use this option, you have to ensure that the "/proc file system
|
|
|
|
support" (CONFIG_PROC_FS) is enabled, too.

[PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinity
When handling writes to /proc/irq, current code is re-programming rte
entries directly. This is not recommended and could potentially cause
chipset's to lockup, or cause missing interrupts.
CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the
interrupt is pending. The same needs to be done for /proc/irq handling as well.
Otherwise user space irq balancers are really not doing the right thing.
- Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for
lack of a generic name.
- added move_irq out of IRQ_BALANCE, and added this same to X86_64
- Added new proc handler for write, so we can do deferred write at irq
handling time.
- Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead
it now shows only active cpu masks, or exactly what was set.
- Provided a common move_irq implementation, instead of duplicating
when using generic irq framework.
Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off.
Tested UP builds as well.
MSI testing: tbd: I have cards, need to look for a x-over cable, although I
did test an earlier version of this patch. Will test in a couple days.

Kprobes allows you to trap at almost any kernel address and
|
|
|
|
execute a callback function. register_kprobe() establishes
|
|
|
|
a probepoint and specifies the callback. Kprobes is useful
|
|
|
|
for kernel debugging, non-intrusive instrumentation and testing.
|
|
|
|
If in doubt, say "N".
