2005-07-29[ACPI] Always set P-state on initializationDominik Brodowski
Otherwise a platform that supports ACPI based cpufreq and boots up at lowest possible speed could stay there forever. This because the governor may request max speed, but the code doesn't update if there is no change in speed, and it assumed the initial state of max speed. http://bugzilla.kernel.org/show_bug.cgi?id=4634 Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2005-07-29[ACPI] Add "ec_polling" boot optionLuming Yu
EC burst mode benefits many machines, some of them significantly. However, our current implementation fails on some machines such as Rafael's Asus L5D. This patch restores the alternative EC polling code, which can be enabled at boot time via "ec_polling" http://bugzilla.kernel.org/show_bug.cgi?id=4665 Signed-off-by: Luming Yu <luming.yu@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2005-07-12ACPICA 20050408 from Bob MooreRobert Moore
Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>

2005-07-11[ACPI] Bind PCI devices with ACPI devicesDavid Shaohua Li
Implement the framework for binding physical devices with ACPI devices. A physical bus like PCI bus should create a 'acpi_bus_type', with: .find_device: For device which has parent such as normal PCI devices. .find_bridge: It's for special devices, such as PCI root bridge or IDE controller. Such devices generally haven't a parent or ->bus. We use the special method to get an ACPI handle.

2005-06-17When cfq I/O scheduler is selected, get_request() in __make_request() callsKiyoshi Ueda
__cfq_get_queue(). __cfq_get_queue() finds an existing queue (struct cfq_queue) of the current process for the device and returns it. If it's not found, __cfq_get_queue() creates and returns a new one if __cfq_get_queue() is called with __GFP_WAIT flag, or __cfq_get_queue() returns NULL (this means that get_request() fails) if no __GFP_WAIT flag. On the other hand, in __make_request(), get_request() is called without __GFP_WAIT flag at the first time. Thus, the get_request() fails when there is no existing queue, typically when it's called for the first I/O request of the process to the device. Though it will be followed by get_request_wait() for general case, __make_request() will just end the I/O with an error (EWOULDBLOCK) when the request was for read-ahead.
