[RFC v4 2/6] sched/deadline: improve the tracking of active utilization

From: Luca Abeni This patch implements a more theoretically sound algorithm for tracking active utilization: instead of decreasing it when a task blocks, use a timer (the "inactive timer", named after the "Inactive" task state of the GRUB algorithm) to decrease the active

[RFC v4 1/6] sched/deadline: track the active utilization

From: Luca Abeni Active utilization is defined as the total utilization of active (TASK_RUNNING) tasks queued on a runqueue. Hence, it is increased when a task wakes up and is decreased when a task blocks. When a task is migrated from CPUi to CPUj, immediately subtract the

[RFC v4 5/6] sched/deadline: do not reclaim the whole CPU bandwidth

From: Luca Abeni Original GRUB tends to reclaim 100% of the CPU time... And this allows a CPU hog to starve non-deadline tasks. To address this issue, allow the scheduler to reclaim only a specified fraction of CPU time. Signed-off-by: Luca Abeni ---

[RFC v4 4/6] sched/deadline: implement GRUB accounting

From: Luca Abeni According to the GRUB (Greedy Reclaimation of Unused Bandwidth) reclaiming algorithm, the runtime is not decreased as "dq = -dt", but as "dq = -Uact dt" (where Uact is the per-runqueue active utilization). Hence, this commit modifies the runtime accounting

[RFC v4 3/6] sched/deadline: fix the update of the total -deadline utilization

From: Luca Abeni Now that the inactive timer can be armed to fire at the 0-lag time, it is possible to use inactive_task_timer() to update the total -deadline utilization (dl_b->total_bw) at the correct time, fixing dl_overflow() and __setparam_dl(). Signed-off-by: Luca

[PATCH 0/3] ata: add m68k/Atari Falcon PATA support

Hi, This patchset adds m68k/Atari Falcon PATA support to libata. The major difference in the new libata's pata_falcon host driver when compared to legacy IDE's falconide host driver is that we are using polled PIO mode and thus avoiding the need for STDMA locking magic altogether. Tested under

[PATCH 3/3] ata: add Atari Falcon PATA controller driver

Add Atari Falcon PATA controller driver. The major difference when compared to legacy IDE's falconide host driver is that we are using polled PIO mode and thus avoiding the need for STDMA locking magic altogether. Tested under ARAnyM emulator. Signed-off-by: Bartlomiej Zolnierkiewicz

[PATCH 2/3] ata: pass queued command to ->sff_data_xfer method

For Atari Falcon PATA support we need to check the current command in its ->sff_data_xfer method. Update core code and all users accordingly. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz ---

[PATCH 0/3] cpufreq: intel_pstate: Locking and limits fix-ups

Hi, This series fixes a couple of possible locking issues and limits synchronization in intel pstate. [1/3] Add locking to intel_pstate_resume(). [2/3] Add locking to intel_cpufreq_verify_policy(). [3/3] Always keep all limits settings in sync. Thanks, Rafael

[PATCH 2/3] cpufreq: intel_pstate: Use locking in intel_cpufreq_verify_policy()

From: Rafael J. Wysocki Race conditions are possible if intel_cpufreq_verify_policy() is executed in parallel with global limits updates from sysfs, so the invocation of intel_pstate_update_perf_limits() in it should be carried out under intel_pstate_limits_lock.

[PATCH 1/3] cpufreq: intel_pstate: Use locking in intel_pstate_resume()

From: Rafael J. Wysocki Theoretically, intel_pstate_resume() may be executed in parallel with intel_pstate_set_policy(), if the latter is invoked via cpufreq_update_policy() as a result of a notification, so use intel_pstate_limits_lock in there too to avoid race

[PATCH 3/3] cpufreq: intel_pstate: Always keep all limits settings in sync

From: Rafael J. Wysocki Make intel_pstate update per-logical-CPU limits when the global settings are changed to ensure that they are always in sync and users will not see confusing values in per-logical-CPU sysfs attributes. This also fixes the problem that setting
