* [PPP]: handle misaligned accessesPhilippe De Muyter2005-11-081-3/+14
| | | | | | | | | | | | | | From: "Philippe De Muyter" <phdm@macqel.be> This patch avoids ppp-generated kernel crashes on machines where unaligned accesses are forbidden (ie: m68000), by fixing ppp alignment setting for reused skb's.

| | | | | | | | | | | | | | | | | | | | This adds a new thermal control framework for PowerMac, along with the implementation for PowerMac8,1, PowerMac8,2 (iMac G5 rev 1 and 2), and PowerMac9,1 (latest single CPU desktop). In the future, I expect to move the older G5 thermal control to the new framework as well.

| | | | | | | | | | | | | | | | | | | | This patch adds the ability to the SMU driver to recover missing calibration partitions from the SMU chip itself.

| * | | [CPUFREQ] Avoid the ondemand cpufreq governor to use a too high frequency ↵Dave Jones2005-09-201-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | for stats. The problem is in the ondemand governor, there is a periodic measurement of the CPU usage. This CPU usage is updated by the scheduler after every tick (basically, by adding 1 either to "idle" or to "user" or to "system"). So if the frequency of the governor is too high, the stat will be meaningless (as mostly no number have changed). So this patch checks that the measurements are separated by at least 10 ticks. It means that by default, stats will have about 5% error (20 ticks). Of course those numbers can be argued but, IMHO, they look sane. The patch also includes a small clean-up to check more explictly the result of the conversion from ns to µs being null. Let's note that (on x86) this has never been really needed before 2.6.13 because HZ was always 1000. Now that HZ can be 100, some CPU might be affected by this problem. For instance when HZ=100, the centrino ,which has a 10µs transition latency, would lead to the governor allowing to read stats every tick (10ms)!

It turned out that this was because of a race in the timeout handling do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and sometimes if the timer interrupt handling takes more than one or even two jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just after chip_ready() call, the driver bails out from a ready polling loop despite the chip has actually become ready while all those interrupts were handled. To deal with this issue, extra check for chip ready is neccessary on timeout expiration (and the checks should better be reordered). As do_write_oneword() uses the same approach, it needs to also be changed.
