Hi Linus, please pull from: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git release All of these patches have been through -mm, and have been re-based to apply cleanly to 2.6.19-rc2 The C-state changes add support for recently released MONITOR/MWAIT hardware extensions for deep C-states -- a lower overhead method than the IO port method they replace. The EC driver deltas are a long overdue clean-up -- no significant functionality. The msi-laptop driver is new. Although we are at rc2, I think it is a good idea to push it upstream b/c it is a better example than the current upstream platform-specific drivers at using ACPI without _exposing_ ACPI to the user. Andrew seemed supportive of me not waiting to push it upstream, so here you go. thanks! -Len ps. a plain patch is also available here: ftp://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test/2.6.19/acpi-test-20060707-2.6.19-rc2.diff.gz Documentation/ibm-acpi.txt | 75 - MAINTAINERS | 7 arch/i386/kernel/acpi/boot.c | 10 arch/i386/kernel/acpi/cstate.c | 122 +++ arch/i386/kernel/process.c | 22 arch/x86_64/kernel/process.c | 22 drivers/acpi/asus_acpi.c | 67 - drivers/acpi/battery.c | 14 drivers/acpi/ec.c | 1096 +++++++---------------------- drivers/acpi/events/evmisc.c | 14 drivers/acpi/events/evrgnini.c | 13 drivers/acpi/ibm_acpi.c | 2 drivers/acpi/motherboard.c | 6 drivers/acpi/osl.c | 34 drivers/acpi/pci_link.c | 2 drivers/acpi/power.c | 9 drivers/acpi/processor_core.c | 2 drivers/acpi/processor_idle.c | 103 +- drivers/acpi/sbs.c | 20 drivers/acpi/tables/tbget.c | 2 drivers/acpi/tables/tbrsdt.c | 2 drivers/misc/Kconfig | 19 drivers/misc/Makefile | 1 drivers/misc/msi-laptop.c | 395 ++++++++++ include/acpi/pdc_intel.h | 9 include/acpi/processor.h | 18 include/asm-i386/processor.h | 2 include/asm-x86_64/processor.h | 2 include/linux/acpi.h | 3 29 files changed, 1088 insertions(+), 1005 deletions(-) through these commits: Alexey Dobriyan (1): ACPI: asus_acpi: don't printk on writing garbage to proc files Alexey Y.

We were bitten by this when we made an x86_64 platform whose BIOS provides an Interrupt Source Override for the SCI itself. Apparently the override has no effect for the System Control Interrupt, and this appears to be because of the way the SCI is setup in the ACPI code. It does not handle the case where busirq != gsi. The code that sets up the SCI routing assumes that bus irq == global irq. So there is simply no provision for telling it otherwise. The attached patch provides this mechanism. This patch provided by David Bulkow, was tested on an i386 platform, which does not use the SCI override, and also on an x86_64 platform which does use an override.

The old _read(), _write(), _query() are just special cases of these functions. Then unified the code in acpi_ec_poll_transaction() and acpi_ec_intr_transaction() a little more. Both functions are now just wrappers around the new acpi_ec_transaction_unlocked() function. The latter contains the EC access logic, the two original function now just do their special way of locking and call the the new function for the actual work. This saves a lot of very similar code. The primary reason for doing this, however, is that my driver for MSI 270 laptops needs to issue some non-standard EC commands in a safe way. Due to this I added a new exported function similar to ec_write()/ec_write() which is called ec_transaction() and is essentially just a wrapper around acpi_ec_{poll,intr}_transaction().

Refer: Intel Architecture Software Developer's Manual http://www.intel.com/design/Pentium4/manuals/253668.htm Platform firmware exports the support for Native C-state to OS using ACPI _PDC and _CST methods. Refer: Intel Processor Vendor-Specific ACPI: Interface Specification http://www.intel.com/technology/iapc/acpi/downloads/302223.htm With Processor Native C-state, we use 'MWAIT' instruction on the processor to enter different C-states (C1, C2, C3). We won't use the special IO ports to enter C-state and no SMM mode etc required to enter C-state. Overall this will mean better C-state support. One major advantage of using MWAIT for all C-states is, with this and "treat interrupt as break event" feature of MWAIT, we can now get accurate timing for the time spent in C1, C2, .. states.
