5
6the default tuning is a compromise between client power and server
7performance;
8for a server distro like Clear Linux, we don't need to compromise.
9(for non-server usages we have different kernel binaries)
10
11in principle this can be done as a patch to systemd as well, but we have
12a shared
13systemd between usages while we have different kernels, so the logistics
14for where the patch goes work out better here

4Subject: [PATCH 110/126] fs: ext4: fsync: optimize double-fsync() a bunch
5
6There are cases where EXT4 is a bit too conservative sending barriers down to
7the disk; there are cases where the transaction in progress is not the one
8that sent the barrier (in other words: the fsync is for a file for which the
9IO happened more time ago and all data was already sent to the disk).
10
11For that case, a more performing tradeoff can be made on SSD devices (which
12have the ability to flush their dram caches in a hurry on a power fail event)
13where the barrier gets sent to the disk, but we don't need to wait for the
14barrier to complete. Any consecutive IO will block on the barrier correctly.

7the mounting code is reached, so a retry device scan will
8be performed every 0.5 sec for at least 40 sec

4Subject: [PATCH] migrate some systemd defaults to the kernel defaults.
5
6These settings are needed to prevent networking issues when
7the networking modules come up by default without explicit
8settings, which breaks some cases.
9
10We don't want the modprobe settings to be read at boot time
11if we're not going to do anything else ever.

4Subject: [PATCH 117/126] reduce e1000e boot time by tightening sleep ranges
5
6The e1000e driver is a great user of the usleep_range() API,
7and has any nice ranges that in principle help power management.
8
9However the ranges that are used only during system startup are
10very long (and can add easily 100 msec to the boot time) while
11the power savings of such long ranges is irrelevant due to the
12one-off, boot only, nature of these functions.
13
14This patch shrinks some of the longest ranges to be shorter
15(while still using a power friendly 1 msec range); this saves
16100msec+ of boot time on my BDW NUCs
17

4Subject: [PATCH 151/154] mm: Export do_madvise()
5
6Combined with some interesting flags madvise() system call
7allows to free memory more smartly and more efficiently than
8we could do with a simple free(). The issue is that is not
9available for kernel modules that could need it.
10
11In order to solve this lack of support, this patch exports
12do_madvise() so as to make it available to the entire kernel.
13The already existing madvise() system call is unchanged and
14now relies on this new do_madvise() function.

4Subject: [PATCH 152/154] x86: kvm: Notify host to release pages
5
6In context of hypervisors managing several virtual machines, we
7want those virtual machines to give the memory they used back to
8the host when they don't need it anymore.
9
10This patch introduces a new hypercall KVM_HC_RETURN_MEM, allowing
11the guest kernel to notify the host kernel when such event occurs.
12And relying on do_madvise() function that we have previously exported,
13it issues a call to this function when it receives the new hypercall.
14
15Use of do_madvise() with MADV_DONTNEED flag will allow the guest to
16ask for a new page without going through a new hypercall. Instead,
17it will be able to start using that memory again as it will get
18faulted back in as a fresh new page. That's why do_madvise() is more
19efficient than doing vm_unmap() to return some memory to the host.
20
21This patch introduces also a new sysctl kvm_madv_instant_free,
22allowing user to set MADV_FREE advice instead of MADV_DONTNEED.
23Indeed, MADV_FREE saves more performances than using MADV_DONTNEED
24because it does not zero the pages in case the memory has not been
25freed by the kernel. This can happen when there was no need for the
26kernel to get this memory back, meaning it was keeping those pages
27in the right state to be re-used by the same application.
28MADV_FREE being a very recent advice introduced in kernel 4.5, we
29only want to enable it through a sysctl in case the user want to
30use it.

4Subject: [PATCH 153/154] x86: Return memory from guest to host kernel
5
6All virtual machines need memory to perform various tasks, but this
7memory is not released to the host after it is not used anymore. We
8have to wait for the termination of the virtual machine to get this
9memory back into the host.
10
11Ballooning mechanism is close but not designed for the same purpose.
12In case we hit memory limits of the system, the host predicts how much
13memory can be asked back from a guest, and it issues an hypercall to
14retrieve this memory.
15
16The solution proposed is different because it does not wait for host
17needs before to return memory, and it knows precisely how much memory
18it can return.
19
20The way to notify the host side about such a return is to rely on
21the new hypercall KVM_HC_RETURN_MEM. In order to avoid the CPU to be
22overloaded with too many hypercalls, we only return memory blocks of
23order 7 (512k blocks) and higher. This value has been found running
24memory tests using multiple threads allocating/freeing high amount
25of memory. Those tests were run for different order values, and 7 was
26the best tradeoff between the number of hypercalls issued and the
27amount of memory returned to the host.
28
29In order to limit performances impact related to this code addition,
30we check for blocks of order 7 or higher. This means it only costs an
31additional function call and a branch to perform this check.
32
33Furthermore, this code has been added to the "merge" codepath of the
34buddy allocator, which is not as sensitive as the "free" codepath.
35Not all blocks going through the "free" codepath will end up in the
36"merge" codepath because some of them won't find their free buddy.
37But this is a negligible amount since the kernel does not use many
38high order blocks directly. Instead, those bigger blocks are often
39broken into smaller chunks used as low order blocks. At the time
40those small blocks are released, they go through the merge path.
41
42Benchmarks such as ebizzy and will-it-scale have been run in order
43to make sure this patch does not affect kernel performances and no
44significant differences were observed.

4Subject: [PATCH 154/154] sysctl: vm: Fine-grained cache shrinking
5
6Lots of virtual machines are let in idle state for days until they
7are terminated, and they can keep a large amount of memory in their
8cache, meaning this memory cannot be used by other processes.
9
10We tried to release this memory using existing drop_caches sysctl,
11but it led to the complete cache loss while it could have been used
12whether the idle process wakes up. Indeed, the process can't find any
13available cached data and it directly affects performances to rebuild
14it from scratch.
15
16Instead, the solution we want is based on shrinking gradually system
17cache over time. This patch adds a new sysctl shrink_caches_mb so as
18to allow userspace applications indicating the kernel it should shrink
19system cache up to the amount (in MiB) specified.
20
21There is an application called "memshrinker" which uses this new
22mechanism. It runs in the background and periodically releases a
23specified amount of cache. This amount is based on the remaining
24cache on the system, and period is computed to follow a shrinking
25model. It results in saving a lot of memory for other processes
26running on the system.
