-Subject: [PATCH 09/17] zen: Use [defer+madvise] as default khugepaged defrag
- strategy
-
-For some reason, the default strategy to respond to THP fault fallbacks
-is still just madvise, meaning stall if the program wants transparent
-hugepages, but don't trigger a background reclaim / compaction if THP
-begins to fail allocations.  This creates a snowball affect where we
-still use the THP code paths, but we almost always fail once a system
-has been active and busy for a while.
-
-The option "defer" was created for interactive systems where THP can
-still improve performance.  If we have to fallback to a regular page due
-to an allocation failure or anything else, we will trigger a background
-reclaim and compaction so future THP attempts succeed and previous
-attempts eventually have their smaller pages combined without stalling
-running applications.
-
-We still want madvise to stall applications that explicitely want THP,
-so defer+madvise _does_ make a ton of sense.  Make it the default for
-interactive systems, especially if the kernel maintainer left
-transparent hugepages on "always".

-The value is still pretty low, and AMD64-ABI and ELF extended numbering
-supports that, so we should be fine on modern x86 systems.
-
-This fixes crashes in some applications using more than 65535 vmas (also
-affects some windows games running in wine, such as Star Citizen).

-Subject: [PATCH 17/17] ZEN: intel-pstate: Implement "enable" parameter
-
-If intel-pstate is compiled into the kernel, it will preempt the loading
-of acpi-cpufreq so you can take advantage of hardware p-states without
-any friction.
-
-However, intel-pstate is not completely superior to cpufreq's ondemand
-for one reason.  There's no concept of an up_threshold property.
-
-In ondemand, up_threshold essentially reduces the maximum utilization to
-compare against, allowing you to hit max frequencies and turbo boost
-from a much lower core utilization.
-
-With intel-pstate, you have the concept of minimum and maximum
-performance, but no tunable that lets you define, maximum frequency
-means 50% core utilization.  For just this oversight, there's reasons
-you may want ondemand.
-
-Lets support setting "enable" in kernel boot parameters.  This lets
-kernel maintainers include "intel_pstate=disable" statically in the
-static boot parameters, but let users of the kernel override this
-selection.

-Subject: [PATCH] ZEN: Input: evdev - use call_rcu when detaching client
-
-Significant time was spent on synchronize_rcu in evdev_detach_client
-when applications closed evdev devices. Switching VT away from a
-graphical environment commonly leads to mass input device closures,
-which could lead to noticable delays on systems with many input devices.
-
-Replace synchronize_rcu with call_rcu, deferring reclaim of the evdev
-client struct till after the RCU grace period instead of blocking the
-calling application.
-
-While this does not solve all slow evdev fd closures, it takes care of a
-good portion of them, including this simple test:
-
-	#include <fcntl.h>
-	#include <unistd.h>
-
-	int main(int argc, char *argv[])
-	{
-		int idx, fd;
-		const char *path = "/dev/input/event0";
-		for (idx = 0; idx < 1000; idx++) {
-			if ((fd = open(path, O_RDWR)) == -1) {
-				return -1;
-			}
-			close(fd);
-		}
-		return 0;
-	}
-
-Time to completion of above test when run locally:

-	Before: 0m27.111s
-	After:  0m0.018s

-Subject: [PATCH] ZEN: mm: Lower the non-hugetlbpage pageblock size to reduce
- scheduling delays
-
-The page allocator processes free pages in groups of pageblocks, where
-the size of a pageblock is typically quite large (1024 pages without
-hugetlbpage support). Pageblocks are processed atomically with the zone
-lock held, which can cause severe scheduling delays on both the CPU
-going through the pageblock and any other CPUs waiting to acquire the
-zone lock. A frequent offender is move_freepages_block(), which is used
-by rmqueue() for page allocation.
-
-As it turns out, there's no requirement for pageblocks to be so large,
-so the pageblock order can simply be reduced to ease the scheduling
-delays and zone lock contention. PAGE_ALLOC_COSTLY_ORDER is used as a
-reasonable setting to ensure non-costly page allocation requests can
-still be serviced without always needing to free up more than one
-pageblock's worth of pages at a time.
-
-This has a noticeable effect on overall system latency when memory
-pressure is elevated. The various mm functions which operate on
-pageblocks no longer appear in the preemptoff tracer, where previously
-they would spend up to 100 ms on a mobile arm64 CPU processing a
-pageblock with preemption disabled and the zone lock held.

-Subject: [PATCH] ZEN: mm: Don't hog the CPU and zone lock in rmqueue_bulk()
-
-There is noticeable scheduling latency and heavy zone lock contention
-stemming from rmqueue_bulk's single hold of the zone lock while doing
-its work, as seen with the preemptoff tracer. There's no actual need for
-rmqueue_bulk() to hold the zone lock the entire time; it only does so
-for supposed efficiency. As such, we can relax the zone lock and even
-reschedule when IRQs are enabled in order to keep the scheduling delays
-and zone lock contention at bay. Forward progress is still guaranteed,
-as the zone lock can only be relaxed after page removal.
-
-With this change, rmqueue_bulk() no longer appears as a serious offender
-in the preemptoff tracer, and system latency is noticeably improved.

-Queueing in dm-crypt for crypto operations reduces performance on modern
-systems.  As discussed in an article from Cloudflare, they discovered
-that queuing was introduced because the crypto subsystem used to be
-synchronous.  Since it's now asynchronous, we get double queueing when
-using the subsystem through dm-crypt.  This is obviously undesirable and
-reduces throughput and increases latency.
-
-Disable queueing when using our Zen Interactive configuration.

-Subject: [PATCH] pci: Enable overrides for missing ACS capabilities
-
-This an updated version of Alex Williamson's patch from:
-https://lkml.org/lkml/2013/5/30/513
-
-Original commit message follows:
-
-PCIe ACS (Access Control Services) is the PCIe 2.0+ feature that
-allows us to control whether transactions are allowed to be redirected
-in various subnodes of a PCIe topology.  For instance, if two
-endpoints are below a root port or downsteam switch port, the
-downstream port may optionally redirect transactions between the
-devices, bypassing upstream devices.  The same can happen internally
-on multifunction devices.  The transaction may never be visible to the
-upstream devices.
-
-One upstream device that we particularly care about is the IOMMU.  If
-a redirection occurs in the topology below the IOMMU, then the IOMMU
-cannot provide isolation between devices.  This is why the PCIe spec
-encourages topologies to include ACS support.  Without it, we have to
-assume peer-to-peer DMA within a hierarchy can bypass IOMMU isolation.
-
-Unfortunately, far too many topologies do not support ACS to make this
-a steadfast requirement.  Even the latest chipsets from Intel are only
-sporadically supporting ACS.  We have trouble getting interconnect
-vendors to include the PCIe spec required PCIe capability, let alone
-suggested features.
-
-Therefore, we need to add some flexibility.  The pcie_acs_override=
-boot option lets users opt-in specific devices or sets of devices to
-assume ACS support.  The "downstream" option assumes full ACS support
-on root ports and downstream switch ports.  The "multifunction"
-option assumes the subset of ACS features available on multifunction
-endpoints and upstream switch ports are supported.  The "id:nnnn:nnnn"
-option enables ACS support on devices matching the provided vendor
-and device IDs, allowing more strategic ACS overrides.  These options
-may be combined in any order.  A maximum of 16 id specific overrides
-are available.  It's suggested to use the most limited set of options
-necessary to avoid completely disabling ACS across the topology.
-Note to hardware vendors, we have facilities to permanently quirk
-specific devices which enforce isolation but not provide an ACS
-capability.  Please contact me to have your devices added and save
-your customers the hassle of this boot option.
