2009-09-01[CPUFREQ] update Doc for cpuinfo_cur_freq and scaling_cur_freqNaga Chumbalkar
I think the way "cpuinfo_cur_info" and "scaling_cur_info" are defined under ./Documentation/cpu-freq/user-guide.txt can be enhanced. Currently, they are both defined the same way: "Current speed/frequency" of the CPU, in KHz". Below is a patch that distinguishes one from the other. Regards, - naga - ----------------------------------------- Update description for "cpuinfo_cur_freq" and "scaling_cur_freq". Some of the wording is drawn from comments found in ./drivers/cpufreq/cpufreq.c: cpufreq_out_of_sync(): * @old_freq: CPU frequency the kernel thinks the CPU runs at * @new_freq: CPU frequency the CPU actually runs at Signed-off-by: Naga Chumbalkar <nagananda.chumbalkar@hp.com> Signed-off-by: Dave Jones <davej@redhat.com>
2009-09-01[CPUFREQ] Re-enable cpufreq suspend and resume codeDominik Brodowski
Commit 4bc5d3413503 is broken and causes regressions: (1) cpufreq_driver->resume() and ->suspend() were only called on __powerpc__, but you could set them on all architectures. In fact, ->resume() was defined and used before the PPC-related commit 42d4dc3f4e1e complained about in 4bc5d3413503. (2) Therfore, the resume functions in acpi_cpufreq and speedstep-smi would never be called. (3) This means speedstep-smi would be unusuable after suspend or resume. The _real_ problem was calling cpufreq_driver->get() with interrupts off, but it re-enabling interrupts on some platforms. Why is ->get() necessary? Some systems like to change the CPU frequency behind our back, especially during BIOS-intensive operations like suspend or resume. If such systems also use a CPU frequency-dependant timing loop, delays might be off by large factors. Therefore, we need to ascertain as soon as possible that the CPU frequency is indeed at the speed we think it is. You can do this two ways: either setting it anew, or trying to get it. The latter is what was done, the former also has the same IRQ issue. So, let's try something different: defer the checking to after interrupts are re-enabled, by calling cpufreq_update_policy() (via schedule_work()). Timings may be off until this later stage, so let's watch out for resume regressions caused by the deferred handling of frequency changes behind the kernel's back.

2009-08-31ata_piix: parallel scanning on PATA needs an extra lockingBartlomiej Zolnierkiewicz
Commit log for commit 517d3cc15b36392e518abab6bacbb72089658313 ("[libata] ata_piix: Enable parallel scan") says: This patch turns on parallel scanning for the ata_piix driver. This driver is used on most netbooks (no AHCI for cheap storage it seems). The scan is the dominating time factor in the kernel boot for these devices; with this flag it gets cut in half for the device I used for testing (eeepc). Alan took a look at the driver source and concluded that it ought to be safe to do for this driver. Alan has also checked with the hardware team. and it is all true but once we put all things together additional constraints for PATA controllers show up (some hardware registers have per-host not per-port atomicity) and we risk misprogramming the controller. I used the following test to check whether the issue is real: @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_ (timings[pio][1] << 8); } pci_write_config_word(dev, master_port, master_data); - if (is_slave) + if (is_slave) { + if (ap->port_no == 0) { + u8 tmp = slave_data; + + while (slave_data == tmp) { + pci_read_config_byte(dev, slave_port, &tmp); + msleep(50); + } + + dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan " + "race detected\n"); + } pci_write_config_byte(dev, slave_port, slave_data); + } /* Ensure the UDMA bit is off - it will be turned back on if UDMA is selected */ and it indeed triggered the error message. Lets fix all such races by adding an extra locking to ->set_piomode and ->set_dmamode methods for PATA controllers.

2009-08-29drm/i915: Fix CPU-spinning hangs related to fence usage by using an LRU.Eric Anholt
The lack of a proper LRU was partially worked around by taking the fence from the object containing the oldest seqno. But if there are multiple objects inactive, then they don't have seqnos and the first fence reg among them would be chosen. If you were trying to copy data between two mappings, this could result in each page fault stealing the fence from the other argument, and your application hanging. https://bugs.freedesktop.org/show_bug.cgi?id=23566 https://bugs.freedesktop.org/show_bug.cgi?id=23220 https://bugs.freedesktop.org/show_bug.cgi?id=23253 https://bugs.freedesktop.org/show_bug.cgi?id=23366 Cc: Stable Team <stable@kernel.org> Signed-off-by: Eric Anholt <eric@anholt.net> Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

2009-08-27inotify: Ensure we alwasy write the terminating NULL.Eric W. Biederman
Before the rewrite copy_event_to_user always wrote a terqminating '\0' byte to user space after the filename. Since the rewrite that terminating byte was skipped if your filename is exactly a multiple of event_size. Ouch! So add one byte to name_size before we round up and use clear_user to set userspace to zero like /dev/zero does instead of copying the strange nul_inotify_event. I can't quite convince myself len_to_zero will never exceed 16 and even if it doesn't clear_user should be more efficient and a more accurate reflection of what the code is trying to do.
