2006-06-28ACPI: restore comment justifying 'extra' P_LVLx accessAndreas Mohr1-2/+4
While trying to look for superfluous I/O accesses that can be optimized away, I stumbled upon this ACPI sleep I/O access and couldn't figure out why the hell this dummy op was necessary. After more than one hour of internet research, I had collected a sufficient number of documents (among those very old kernel versions) that finally told me what this dummy read was about: STPCLK# doesn't get asserted in time on (some) chipsets, which is why we need to have a dummy I/O read to delay further instruction processing until the CPU is fully stopped.

2006-06-28ACPI: C-States: only demote on current bus mastering activityDominik Brodowski1-3/+4
Only if bus master activity is going on at the present, we should avoid entering C3-type sleep, as it might be a faulty transition. As long as the bm_activity bitmask was based on the number of calls to the ACPI idle function, looking at previous moments made sense. Now, with it being based on what happened this jiffy, looking at this jiffy should be sufficient.

2006-06-28ACPI: C-States: bm_activity improvementsDominik Brodowski1-12/+6
Do not assume there was bus mastering activity if the idle handler didn't get called, as there's only reason to not enter C3-type sleep if there is bus master activity going on. Only for the "promotion" into C3-type sleep bus mastering activity is taken into account, and there only current bus mastering activity, and not pure guessing should lead to the decision on whether to enter C3-type sleep or not. Also, as bm_activity is a jiffy-based bitmask (bit 0: bus mastering activity during this juffy, bit 31: bus mastering activity 31 jiffies ago), fix the setting of bit 0, as it might be called multiple times within one jiffy.

2006-06-28ACPI: C-States: accounting of sleep statesDominik Brodowski2-4/+7
Track the actual time spent in C-States (C2 upwards, we can't determine this for C1), not only the number of invocations. This is especially useful for dynamic ticks / "tickless systems", but is also of interest on normal systems, as any interrupt activity leads to C-States being exited, not only the timer interrupt. The time is being measured in PM timer ticks, so an increase by one equals 279 nanoseconds.

2006-06-28ACPI: ACPICA 20060623Bob Moore28-470/+563
Implemented a new acpi_spinlock type for the OSL lock interfaces. This allows the type to be customized to the host OS for improved efficiency (since a spinlock is usually a very small object.) Implemented support for "ignored" bits in the ACPI registers. According to the ACPI specification, these bits should be preserved when writing the registers via a read/modify/write cycle. There are 3 bits preserved in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. http://bugzilla.kernel.org/show_bug.cgi?id=3691 Implemented the initial deployment of new OSL mutex interfaces. Since some host operating systems have separate mutex and semaphore objects, this feature was requested. The base code now uses mutexes (and the new mutex interfaces) wherever a binary semaphore was used previously. However, for the current release, the mutex interfaces are defined as macros to map them to the existing semaphore interfaces. Fixed several problems with the support for the control method SyncLevel parameter. The SyncLevel now works according to the ACPI specification and in concert with the Mutex SyncLevel parameter, since the current SyncLevel is a property of the executing thread. Mutual exclusion for control methods is now implemented with a mutex instead of a semaphore. Fixed three instances of the use of the C shift operator in the bitfield support code (exfldio.c) to avoid the use of a shift value larger than the target data width. The behavior of C compilers is undefined in this case and can cause unpredictable results, and therefore the case must be detected and avoided. (Fiodor Suietov) Added an info message whenever an SSDT or OEM table is loaded dynamically via the Load() or LoadTable() ASL operators. This should improve debugging capability since it will show exactly what tables have been loaded (beyond the tables present in the RSDT/XSDT.)

2006-06-28ACPIPHP: prevent duplicate slot numbers when no _SUNKristen Accardi1-2/+7
Dock bridges generally do not implement _SUN, yet show up as ejectable slots. If you have more than one ejectable slot that does not implement SUN, with the current code you will get duplicate slot numbers. So, if there is no _SUN, use the current count of the number of slots found instead.

2006-06-27ACPI: acpi_os_wait_semaphore(): silence complaintBjorn Helgaas1-1/+1
The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out and return True without acquiring the semaphore. There's no indication in the spec that this is an actual error, so this message should be debug-only, as the message for successful acquisition is. This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas' recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.
