| * ACPI: SCI interrupt source overrideKimball Murray2006-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux group at Stratus Technologies has come across an issue with SCI routing under ACPI. 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.

| |/ | | | | | | | | | | | | | | | | | | On acquiring the ACPI global lock, if there were sleepers on the lock, we used to use acpi_os_execute() to defer a thread which would signal sleepers.

In addition it allows access to the WLAN and Bluetooth states through a platform driver (/sys/devices/platform/msi-laptop-pf/).

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().

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intel processors starting with the Core Duo support support processor native C-state using the MWAIT instruction. 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.

* [PATCH] Fix up mmap_kmemFranck Bui-Huu2006-10-13
| | | | | | | | | | | | | | | | | | | | | | | vma->vm_pgoff is an pfn _offset_ relatif to the begining of the memory start. The previous code was doing at first: vma->vm_pgoff << PAGE_SHIFT which results into a wrong physical address since some platforms have a physical mem start that can be different from 0. After that the previous call __pa() on this wrong physical address, however __pa() is used to convert a _virtual_ address into a physical one. This patch rewrites this convertion. It calculates the pfn of PAGE_OFFSET which is the pfn of the mem start then it adds the vma->vm_pgoff to it. It also uses virt_to_phys() instead of __pa() since the latter shouldn't be used by drivers. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
