[PATCH] ia64: use i386 dmi_scan.c
Enable DMI table parsing on ia64.
Andi Kleen has a patch in his x86_64 tree which enables the use of i386
dmi_scan.c on x86_64. dmi_scan.c functions are being used by the
drivers/char/ipmi/ipmi_si_intf.c driver for autodetecting the ports or
memory spaces where the IPMI controllers may be found.
This patch adds equivalent changes for ia64 as to what is in the x86_64
tree. In addition, I reworked the DMI detection, such that on EFI-capable
systems, it uses the efi.smbios pointer to find the table, rather than
brute-force searching from 0xF0000. On non-EFI systems, it continues the
brute-force search.
My test system, an Intel S870BN4 'Tiger4', aka Dell PowerEdge 7250, with
latest BIOS, does not list the IPMI controller in the ACPI namespace, nor
does it have an ACPI SPMI table. Also note, currently shipping Dell x8xx
EM64T servers don't have these either, so DMI is the only method for
obtaining the address of the IPMI controller.

[IA64] esi-support
Add support for making ESI calls [1]. ESI stands for "Extensible SAL
specification" and is basically a way for invoking firmware
subroutines which are identified by a GUID. I don't know whether ESI
is used by vendors other than HP (if you do, please let me know) but
as firmware "backdoors" go, this seems one of the cleaner methods, so
it seems reasonable to support it, even though I'm not aware of any
publicly documented ESI calls. I'd have liked to make the ESI module
completely stand-alone, but unfortunately that is not easily (or not
at all) possible because in order to make ESI calls in physical mode,
a small stub similar to the EFI stub is needed in the kernel proper.
I did try to create a stub that would work in user-level, but it
quickly got ugly beyond recognition (e.g., the stub had to make
assumptions about how the module-loader generated call-stubs work) and
I didn't even get it to work (that's probably fixable, but I didn't
bother because I concluded it was too ugly anyhow). While it's not
terribly elegant to have kernel code which isn't actively used in the
kernel proper, I think it might be worth making an exception here for
two reasons: the code is trivially small (all that's really needed is
esi_stub.S) and by including it in the normal kernel distro, it might
encourage other OEMs to also use ESI, which I think would be far
better than each inventing their own firmware "backdoor".
The code was originally written by Alex. I just massaged and packaged
it a bit (and perhaps messed up some things along the way...).
Changes since first version of patch that was posted to mailing list:
* Export ia64_esi_call and ia64_esi_call_phys() as GPL symbols.
* Disallow building esi.c as a module for now. Building as a module
would currently lead to an unresolved reference to "sal_lock" on SMP kernels
because that symbol doesn't get exported.
* Export esi_call_phys() only if ESI is enabled.
* Remove internal stuff from esi.h and add a "proc_type" argument to
ia64_esi_call() such that serialization-requirements can be expressed (ESI
follows SAL here, where procedure calls may have to be serialized, are
MP-safe, or MP-safe andr reentrant).

kexec is a system call that implements the ability to shutdown your
|
|
|
|
current kernel, and to start another kernel. It is like a reboot
|
2007-05-09 05:12:20 +00:00
|
|
|
but it is independent of the system firmware. And like a reboot
|
2006-12-07 17:51:35 +00:00
|
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
|
2007-10-19 23:34:40 +00:00
|
|
|
The name comes from the similarity to the exec system call.

|
|
It is an ongoing process to be certain the hardware in a machine
|
|
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
|
|
initially work for you. It may help to enable device hotplugging
|
|
|
|
support. As of this writing the exact hardware interface is
|
|
|
|
strongly in flux, so no good recommendation can be made.

[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.
