refperf: Hoist function-pointer calls out of the loop
Current runs show PREEMPT=n rcu_read_lock()/rcu_read_unlock() pairs consuming between 20 and 30 nanoseconds, when in fact the actual value is zero, give or take the barrier() asm's effect on compiler optimizations. The additional overhead is caused by function calls through pointers (especially in these days of Spectre mitigations) and perhaps also needless argument passing, a non-const loop limit, and an upcounting loop. This commit therefore combines the ->readlock() and ->readunlock() function pointers into a single ->readsection() function pointer that takes the loop count as a const parameter and keeps any data passed from the read-lock to the read-unlock internal to this new function. These changes reduce the measured overhead of the aforementioned PREEMPT=n rcu_read_lock()/rcu_read_unlock() pairs from between 20 and 30 nanoseconds to somewhere south of 500 picoseconds.

refperf: Add holdoff parameter to allow CPUs to come online
This commit adds an rcuperf module parameter named "holdoff" that defaults to 10 seconds if refperf is built in and to zero otherwise. The assumption is that all the CPUs are online by the time that the modprobe and insmod commands are going to do anything, and that normal systems will have all the CPUs online within ten seconds. Larger systems may take many tens of seconds or even minutes to get to this point, hence this being a module parameter instead of being a hard-coded constant.

rcuperf: Add comments explaining the high reader overhead
This commit adds comments explaining why the readers have otherwise insane levels of measurement overhead, namely that they are intended as a test load for update-side performance measurements, not as a straight-up read-side performance test. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> |

refperf: Add a test to measure performance of read-side synchronization
Add a test for comparing the performance of RCU with various read-side synchronization mechanisms. The test has proved useful for collecting data and performing these comparisons. Currently RCU, SRCU, reader-writer lock, reader-writer semaphore and reference counting can be measured using refperf.perf_type parameter. Each invocation of the test runs measures performance of a specific mechanism. The maximum number of CPUs to concurrently run readers on is chosen by the test itself and is 75% of the total number of CPUs. So if you had 24 CPUs, the test runs with a maximum of 18 parallel readers. A number of experiments are conducted, and in each experiment, the number of readers is increased by 1, upto the 75% of CPUs mark. During each experiment, all readers execute an empty loop with refperf.loops iterations and time the total loop duration. This is then averaged. Example output: Parameters "refperf.perf_type=srcu refperf.loops=2000000" looks like: [ 3.347133] srcu-ref-perf: [ 3.347133] Threads Time(ns) [ 3.347133] 1 36 [ 3.347133] 2 34 [ 3.347133] 3 34 [ 3.347133] 4 34 [ 3.347133] 5 33 [ 3.347133] 6 33 [ 3.347133] 7 33 [ 3.347133] 8 33 [ 3.347133] 9 33 [ 3.347133] 10 33 [ 3.347133] 11 33 [ 3.347133] 12 33 [ 3.347133] 13 33 [ 3.347133] 14 33 [ 3.347133] 15 32 [ 3.347133] 16 33 [ 3.347133] 17 33 [ 3.347133] 18 34 Signed-off-by: Joel Fernandes (Google) <joel@joelfernandes.org> Signed-off-by: Paul E.

ARM: OMAP fixes for v5.8
The OMAP developers are particularly active at hunting down regressions,
so this is a separate branch with OMAP specific fixes for the v5.8:
As Tony explains
"The recent display subsystem (DSS) related platform data changes
caused display related regressions for suspend and resume. Looks like
I only tested suspend and resume before dropping the legacy platform
data, and forgot to test it after dropping it. Turns out the main issue
was that we no longer have platform code calling pm_runtime_suspend
for DSS like we did for the legacy platform data case, and that fix
is still being discussed on the dri-devel list and will get merged
separately. The DSS related testing exposed a pile other other display
related issues that also need fixing though":
- Fix ti-sysc optional clock handling and reset status checks
for devices that reset automatically in idle like DSS
- Ignore ti-sysc clockactivity bit unless separately requested
to avoid unexpected performance issues
- Init ti-sysc framedonetv_irq to true and disable for am4
- Avoid duplicate DSS reset for legacy mode with dts data
- Remove LCD timings for am4 as they cause warnings now that we're
using generic panels
Other OMAP changes from Tony include:
- Fix omap_prm reset deassert as we still have drivers setting the
pm_runtime_irq_safe() flag
- Flush posted write for ti-sysc enable and disable
- Fix droid4 spi related errors with spi flags
- Fix am335x USB range and a typo for softreset
- Fix dra7 timer nodes for clocks for IPU and DSP
- Drop duplicate mailboxes after mismerge for dra7
- Prevent pocketgeagle header line signal from accidentally setting
micro-SD write protection signal by removing the default mux
- Fix NFSroot flakeyness after resume for duover by switching the
smsc911x gpio interrupt to back to level sensitive
- Fix regression for omap4 clockevent source after recent system
timer changes
- Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"
phy-mode
- One patch to convert am3/am4 DT files to use the regular sdhci-omap
driver instead of the old hsmmc driver, this was meant for the
merge window but got lost in the process.

Peter Zijlstra says:

These patches address a number of instrumentation issues that were found after
the x86/entry overhaul. When combined with rcu/urgent and objtool/urgent, these
patches make UBSAN/KASAN/KCSAN happy again.
Part of making this all work is bumping the minimum GCC version for KASAN
builds to gcc-8.3, the reason for this is that the __no_sanitize_address
function attribute is broken in GCC releases before that.
No known GCC version has a working __no_sanitize_undefined, however because the
only noinstr violation that results from this happens when an UB is found, we
treat it like WARN. That is, we allow it to violate the noinstr rules in order
to get the warning out.

Instead of relying on BUG_ON() to ensure the various data structures line up, use a bunch of horrible unions to make it all automatic.

sched/core: Fix PI boosting between RT and DEADLINE tasks
syzbot reported the following warning:
WARNING: CPU: 1 PID: 6351 at kernel/sched/deadline.c:628
enqueue_task_dl+0x22da/0x38a0 kernel/sched/deadline.c:1504
At deadline.c:628 we have:
623 static inline void setup_new_dl_entity(struct sched_dl_entity *dl_se)
624 {
625 struct dl_rq *dl_rq = dl_rq_of_se(dl_se);
626 struct rq *rq = rq_of_dl_rq(dl_rq);
627
628 WARN_ON(dl_se->dl_boosted);
629 WARN_ON(dl_time_before(rq_clock(rq), dl_se->deadline));
[...]
}
Which means that setup_new_dl_entity() has been called on a task
currently boosted. This shouldn't happen though, as setup_new_dl_entity()
is only called when the 'dynamic' deadline of the new entity
is in the past w.r.t. rq_clock and boosted tasks shouldn't verify this
condition.
Digging through the PI code I noticed that what above might in fact happen
if an RT tasks blocks on an rt_mutex hold by a DEADLINE task. In the
first branch of boosting conditions we check only if a pi_task 'dynamic'
deadline is earlier than mutex holder's and in this case we set mutex
holder to be dl_boosted. However, since RT 'dynamic' deadlines are only
initialized if such tasks get boosted at some point (or if they become
DEADLINE of course), in general RT 'dynamic' deadlines are usually equal
to 0 and this verifies the aforementioned condition.
Fix it by checking that the potential donor task is actually (even if
temporary because in turn boosted) running at DEADLINE priority before
using its 'dynamic' deadline value.

sched/deadline: Initialize ->dl_boosted

This happens because the ->dl_boosted flag is currently not initialized by
__dl_clear_params() (unlike the other flags) and setup_new_dl_entity()
rightfully complains about it.
Initialize dl_boosted to 0.

Missed sdhci patch for am3 and am4

There was a display subsystem related suspend and resume regression found recently and looks like I forgot to send a pull request for this patch while debugging the regression.

Fixes for omaps for v5.8
The recent display subsystem (DSS) related platform data changes caused display related regressions for suspend and resume. Looks like I only tested suspend and resume before dropping the legacy platform data, and forgot to test it after dropping it. Turns out the main issue was that we no longer have platform code calling pm_runtime_suspend for DSS like we did for the legacy platform data case, and that fix is still being discussed on the dri-devel list and will get merged separately. The DSS related testing exposed a pile other other display related issues that also need fixing though: - Fix ti-sysc optional clock handling and reset status checks for devices that reset automatically in idle like DSS - Ignore ti-sysc clockactivity bit unless separately requested to avoid unexpected performance issues - Init ti-sysc framedonetv_irq to true and disable for am4 - Avoid duplicate DSS reset for legacy mode with dts data - Remove LCD timings for am4 as they cause warnings now that we're using generic panels Then there is a pile of other fixes not related to the DSS: - Fix omap_prm reset deassert as we still have drivers setting the pm_runtime_irq_safe() flag - Flush posted write for ti-sysc enable and disable - Fix droid4 spi related errors with spi flags - Fix am335x USB range and a typo for softreset - Fix dra7 timer nodes for clocks for IPU and DSP - Drop duplicate mailboxes after mismerge for dra7 -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAl7iS6oRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXPLLBAAzcABBnwfnk+vjSHJ9QnQ/9LfJTLUIrkH ZpB/CR6VC86STjpePaNpVN/fm5sODN4zvtpsuAvJgyF+9Hp3GRPxglC4g9cAmU8x VFQepzgOLOQ/ubPesVWa14RgAoK29GNvfzihCKGmhOq7kz7I/PDIQr8txjw8KHqV M8oVefWL6l95z1MwVEKvsebyloBwYx9q/+Q5bipoV/GvrQnMjaCFzEaO6n8nH0Xc T6XsKA+4hCr94tHM3jgfSdIQYFrq38H84t986ExMVfIhh3LfNkNu7CrSIWcjTgEY jAs/hnPQ/JzMuBivweCrfkpQYy4D/GOjueQJy2Mf3deMJUWEsgZzMOML743W307j HvGB5c3i1HgXir6PtjQFP4RqQQpQN1b4xjYEgvd8SB6xnrbdP43YsNrm9gnqbWd8 yNqiY2+uEh7OFyOJe0Ikrr1DNh3K0dSmtqrdhtWor165W0sAqlgjFjrjH1/xcQrN XWhjBCl/NAODNZqbxU4l6rjiSU8J0cGr8wJrZNLe4itZy9R2jPInTv8FSpfcNI32 cVdDfPc4SVl8zsfZq4vhDrS/JVG7Sp/DXXQIG04wMlA6vyK4YAHh0U40121aAE8E AwzOh++cCeZPQB+i3qCkRMLDohC7IJVvZZ/KN1mp43dDEW+epx5tct0ZmfElr4uX Vg84CHL/I28= =fT9A -----END PGP SIGNATURE----- Merge tag 'omap-for-v5.8/fixes-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps for v5.8 The recent display subsystem (DSS) related platform data changes caused display related regressions for suspend and resume.

afs: Fix storage of cell names
The cell name stored in the afs_cell struct is a 64-char + NUL buffer -
when it needs to be able to handle up to AFS_MAXCELLNAME (256 chars) + NUL.
Fix this by changing the array to a pointer and allocating the string.

Some tiny char/misc driver fixes for 5.8-rc3. "largest" changes are in the mei driver, to resolve some reported problems and add some new device ids.

kgdb patches for 5.8-rc3
The main change here is a fix for a number of unsafe interactions between kdb and the console system. The fixes are specific to kdb (pure kgdb debugging does not use the console system at all). On systems with an NMI then kdb, if it is enabled, must get messages to the user despite potentially running from some "difficult" calling contexts. These fixes avoid using the console system where we have been provided an alternative (safer) way to interact with the user and, if using the console system in unavoidable, use oops_in_progress for deadlock avoidance. These fixes also ensure kdb honours the console enable flag. Also included is a fix that wraps kgdb trap handling in an RCU read lock to avoids triggering diagnostic warnings. This is a wide lock scope but this is OK because kgdb is a stop-the-world debugger. When we stop the world we put all the CPUs into holding pens and this inhibits RCU update anyway.

When we stop the world we put all the CPUs into holding pens and this inhibits RCU update anyway" * tag 'kgdb-5.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/danielt/linux: kgdb: Avoid suspicious RCU usage warning kdb: Switch to use safer dbg_io_ops over console APIs kdb: Make kdb_printf() console handling more robust kdb: Check status of console prior to invoking handlers kdb: Re-factor kdb_printf() message write code |
