| * [CPUFREQ] Fix sysfs_create_file return value handlingTobias Klauser2007-06-211-3/+6
| | | | | | | | | | | | | | | | | | | | Commit 0a4b2ccc555fa2ca6873d60219047104e4805d45 in cpufreq.git eliminates the build warnings but does not pass on the error code of sysfs_create_file to the function calling cpufreq_add_dev. Instead some previous value of ret would be returned. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Dave Jones <davej@redhat.com>
| * [CPUFREQ] ondemand: fix tickless accounting and software coordination bugVenki Pallipadi2007-06-211-7/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With tickless kernel and software coordination os P-states, ondemand can look at wrong idle statistics. This can happen when ondemand sampling is happening on CPU 0 and due to software coordination sampling also looks at utilization of CPU 1. If CPU 1 is in tickless state at that moment, its idle statistics will not be uptodate and CPU 0 thinks CPU 1 is idle for less amount of time than it actually is. This can be resolved by looking at all the busy times of CPUs, which is accurate, even with tickless, and use that to determine idle time in a round about way (total time - busy time). Thanks to Arjan for originally reporting the ondemand bug on Lenovo T61. Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Signed-off-by: Dave Jones <davej@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | powernow-k8 really needs to use ACPI to function on SMP systems. The current Kconfig allows us to build kernels which fail mysteriously for some users due to us trying to automatically enable this, and getting it wrong.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Current version of "bm status" bit test works as long as no USB device is in use. When USB device is plugged in ACPI function in this context is always returning 1. Until reboot. Direct I/O is working fine even when many USB devices are connected. Change bm_timeout value to less annoying. 1000 is still much more then worst case observed and it is much better when status bit gets stuck.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Longhaul with voltage scaling enabled works great on Ezra CPU (Longhaul ver. 2). As long as "conservative" governor is used. Both "ondemand" and "userspace" can change voltage from min to max at once. Motherboard unfortunatly turns off when vid difference is big. Longhaul was printing warning message, but it is not enough.

| | | | | | | | | | | | | | | | | | | | | | It is good idea to wait for PCI bus to become idle before frequency change. Thanks to ACPI it is possible.

The first cpu into OS_MCA grabs the ia64_mca_serialize lock. Subsequent cpus wait for that lock, preventing them from reporting in as rendezvoused. The first cpu waits 5 seconds then complains that all the cpus have not rendezvoused. The first cpu then handles its MCA and frees up all the rendezvoused cpus and releases the ia64_mca_serialize lock. One of the subsequent cpus going thought OS_MCA then gets the ia64_mca_serialize lock, waits another 5 seconds and then complains that none of the other cpus have rendezvoused. This patch allows multiple CPUs to gracefully go through OS_MCA. The first CPU into ia64_mca_handler() grabs a mca_count lock. Subsequent CPUs into ia64_mca_handler() are added to a list of cpus that need to go through OS_MCA (a bit set in mca_cpu), and report in as rendezvoused, and but spin waiting their turn. The first CPU sees everyone rendezvous, handles his MCA, wakes up one of the other CPUs waiting to process their MCA (by clearing one mca_cpu bit), and then waits for the other cpus to complete their MCA handling. The next CPU handles his MCA and the process repeats until all the CPUs have handled their MCA. When the last CPU has handled it's MCA, it sets monarch_cpu to -1, releasing all the CPUs. In testing this works more reliably and faster. Thanks to Keith Owens for suggesting numerous improvements to this code.

The current 'acpiphp' code expects the bus check event to reference the bridge immediately above the slot that received the adapter so the hotplug operation can fail on these systems with the message "acpiphp_glue: cannot get bridge info". This change fixes the problem by re-enumerating all slots that lie below the bridge referenced by the bus check event, including those slots that may be located under lower level PCI-to-PCI bridge(s).

| * | | | PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-1194-459/+190

This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

We can do this once for all devices. Even the pci subsystem needs the revision several times for quirks. The extra u8 member pads out nicely in the pci_dev struct.
