| * | | | | tpm: Adjust the durations if they are too smallStefan Berger2011-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adjust the durations if they are found to be too small, i.e., if they are returned in milliseconds rather than microseconds as some Infineon TPMs are reported to do.

| * | | | | tpm: Use durations returned from TPMStefan Berger2011-07-12

The check of the response packet needs to consider that the return_code field is 0 on success and the size of the expected packet is equivalent to the header size + u32 length indicator for the TPM_GetCapability() result + 3 timeout indicators of type u32. v4: - sysfs entry 'durations' is now a patch of its own - the work-around for TPMs reporting durations in milliseconds is now in a patch of its own v3: - sysfs entry now called 'durations' to resemble TPM-speak (previously was called 'timeouts') v2: - adjusting all timeouts for TPM devices reporting timeouts in msec rather than usec - also displaying in sysfs whether the timeouts are 'original' or 'adjusted' Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Guillaume Chazarain <guichaz@gmail.com> Signed-off-by: Rajiv Andrade <srajiv@linux.vnet.ibm.com>

Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2.

This happened because given an interval t and a time for the current interrupt m we would compute the next time as t + m. This works until we are delayed for > t, in which case we would be writing a new value which is in fact in the past. This can be solved by computing the next time instead as (k * t) + m where k is large enough to be in the future. The exact computation of k is described in a comment to the code. More detail: Assuming an interval of 5 between each expected interrupt we have a normal case of t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t5: interrupt, read t5 from comparator, set next interrupt t5 + 5 t10: interrupt, read t10 from comparator, set next interrupt t10 + 5 ... So, what happens when the interrupt is serviced too late? t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t11: delayed interrupt serviced, read t5 from comparator, set next interrupt t5 + 5, which is in the past! ... counter loops ... t10: Much much later, get the next interrupt. This can happen either because we have interrupts masked for too long (some stupid driver goes on a printk rampage) or just because we are pushing the limits of the interval (too small a period), or both most probably. My solution is to read the main counter as well and set the next interrupt to occur at the right interval, for example: t0: interrupt, read t0 from comparator, set next interrupt t0 + 5 t11: delayed interrupt serviced, read t5 from comparator, set next interrupt t15 as t10 has been missed. t15: back on track.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | apm_mutex is locked by a process (e.g. apm -s) at the start of apm_ioctl() and remains locked while pm_suspend() is called. Any subsequent process trying to ACK the suspend (e.g. apmd) is then blocked at the start of apm_ioctl(), causing the suspend to be delayed for 5 seconds in apm_suspend_notifier() while the ACK times out. In short, ACKs don't work. The driver's data structures are sufficiently protected by assorted locks. And pm_suspend() has its own mutex to prevent reentrancy. Consequently there is no obvious requirement for apm_mutex, which evolved from earlier BKL calls. So let's remove it. Signed-off-by: Paul Parsons <lost.distance@yahoo.com> Acked-by: Rafael J.
