Slightly bumping the minimum round-trip-time adds more tolerance for connections with fluctutating ping to stay connected before the sender-side TCP stack gives up on the packet and considers it lost and the connection broken. Lowering the initial RTT duration works conversely by reducing tolerance for bad networks so that we avoid getting on bad connections in the first place.

One SoC can have multiple CPU speedbins which cannot be represented with current energy model due to fixed capacity per CPU frequency steps. Provide CPU's all possible frequency steps instead of capacities along with corresponding energy costs to be able to support different speedbins.

CAF did not use WALT on msm-4.4 kernels and left out important WALT bits.
Energy cost estimation has been a long lasting challenge for WALT because WALT guides CPU frequency based on the CPU utilization of previous window. Consequently it's not possible to know newly waking-up task's energy cost until WALT's end of the current window. The WALT already tracks 'Previous Runnable Sum' (prev_runnable_sum) and 'Cumulative Runnable Average' (cr_avg). They are designed for CPU frequency guidance and task placement but unfortunately both are not suitable for the energy cost estimation. It's because using prev_runnable_sum for energy cost calculation would make us to account CPU and task's energy solely based on activity in the previous window so for example, any task didn't have an activity in the previous window will be accounted as a 'zero energy cost' task. Energy estimation with cr_avg is what energy_diff() relies on at present. However cr_avg can only represent instantaneous picture of energy cost thus for example, if a CPU was fully occupied for an entire WALT window and became idle just before window boundary, and if there is a wake-up, energy_diff() accounts that CPU is a 'zero energy cost' CPU. As a result, introduce a new accounting unit 'Cumulative Window Demand'. The cumulative window demand tracks all the tasks' demands have seen in current window which is neither instantaneous nor actual execution time. Because task demand represents estimated scaled execution time when the task runs a full window, accumulation of all the demands represents predicted CPU load at the end of window. Thus we can estimate CPU's frequency at the end of current WALT window with the cumulative window demand. The use of prev_runnable_sum for the CPU frequency guidance and cr_avg for the task placement have not changed and these are going to be used for both purpose while this patch aims to add an additional statistics.

Use do_div() instead of "/" operator to fix undefined references to "__aeabi_uldivmod" build error for ARCH=arm. Also in TP_fast_assign(), along with do_div() usage, replace "," with ";" which would have resulted in a syntax error (!), because '#define TP_fast_assign(args...) args' would have stripped off the "," and left white space between these two assignments after CPP phase.

Active balance currently picks one task to migrate from busy cpu to
a chosen cpu (push_cpu). This patch extends active load balance to
recognize a particular task ('push_task') that needs to be migrated to
'push_cpu'. This capability will be leveraged by HMP-aware task
placement in a subsequent patch.

If there have misfit task on one CPU, current code does not handle this situation for nohz idle balance. As result, we can see the misfit task stays run on little core for long time. So this patch check if the CPU has misfit task or not. If has misfit task then kick nohz idle balance so finally can execute active balance.

EAS won't allow NOHZ idle balancer until CPU's over utilized. However nohz_kick_needed() can return true. This causes idle CPU wake up for nothing. Change-Id: I6e548442e29e4f85cda695e4c7101dd591b12fe6 Signed-off-by: Joonwoo Park <[email protected]>
Upmigrate misfit current task upon scheduler tick with stopper. We can kick an random (not necessarily big CPU) NOHZ idle CPU when a CPU bound task is in need of upmigration. But it's not efficient as that way needs following unnecessary wakeups: 1. Busy little CPU A to kick idle B 2. B runs idle balancer and enqueue migration/A 3. B goes idle 4. A runs migration/A, enqueues busy task on B. 5. B wakes up again. This change makes active upmigration more efficiently by doing: 1. Busy little CPU A find target CPU B upon tick. 2. CPU A enqueues migration/A. Change-Id: Ie865738054ea3296f28e6ba01710635efa7193c0 [joonwoop: The original version had logic to reserve CPU.

This patch fixes one of the infrequent conditions in
commit 54b6baeca500 ("sched/fair: Skip frequency updates if CPU about to idle")
where we could have skipped a frequency update. The fix is to use the
correct flag which skips freq updates.
Note that this is a rare issue (can show up only during CFS throttling)
and even then we just do an additional frequency update which we were
doing anyway before the above patch.

We should apply the iowait boost only if cpufreq policy has iowait boost enabled. Also make it a schedutil configuration from sysfs so it can be turned on/off if needed (by default initialize it to the policy value). For systems that don't need/want it enabled, such as those on arm64 based mobile devices that are battery operated, it saves energy when the cpufreq driver policy doesn't have it enabled (details below): Here are some results for energy measurements collected running a YouTube video for 30 seconds: Before: 8.042533 mWh After: 7.948377 mWh Energy savings is ~1.2% Bug: 38010527 Link: https://lkml.org/lkml/2017/5/19/42 Change-Id: If124076ad0c16ade369253840dedfbf870aff927 Signed-off-by: Joel Fernandes <[email protected]>

If someone has the silly idea to write something along those lines:
extern u64 foo(void);
void bar(struct arm_smccc_res *res)
{
arm_smccc_1_1_smc(0xbad, foo(), res);
}
they are in for a surprise, as this gets compiled as:

5c0: d65f03c0 ret

The call to foo "overwrites" the x0 register for the return value,
and we end up calling the wrong secure service.
A solution is to evaluate all the parameters before assigning
anything to specific registers, leading to the expected result:

[ Upstream commit 1a1c851bbd706ea9f3a9756c2d3db28523506d3b ] We meet several NULL pointer issues if configfs_composite_unbind and composite_setup (or composite_disconnect) are running together. These issues occur when do the function switch stress test, the configfs_compsoite_unbind is called from user mode by echo "" to /sys/../UDC entry, and meanwhile, the setup interrupt or disconnect interrupt occurs by hardware. The composite_setup will get the cdev from get_gadget_data, but configfs_composite_unbind will set gadget data as NULL, so the NULL pointer issue occurs. This concurrent is hard to reproduce by native kernel, but can be reproduced by android kernel. In this commit, we introduce one spinlock belongs to structure gadget_info since we can't use the same spinlock in usb_composite_dev due to exclusive running together between composite_setup and configfs_composite_unbind. And one bit flag 'unbind' to indicate the code is at unbind routine, this bit is needed due to we release the lock at during configfs_composite_unbind sometimes, and composite_setup may be run at that time.

[ Upstream commit e24c6447ccb7b1a01f9bf0aec94939e6450c0b4d ]
I compiled with AddressSanitizer and I had these memory leaks while I
was using the tep_parse_format function:
Direct leak of 28 byte(s) in 4 object(s) allocated from:

The token variable in the process_dynamic_array_len function is
allocated in the read_expect_type function, but is not freed before
calling the read_token function.
Free the token variable before calling read_token in order to plug the
leak.

[ Upstream commit 13a6f3153922391e90036ba2267d34eed63196fc ]
When calling the 'ql_sem_spinlock', the driver has already acquired the
spin lock, so the driver should not call 'ssleep' in atomic context.
This bug can be fixed by using 'mdelay' instead of 'ssleep'.
The KASAN's log reveals it:
