android: lowmemkiller: don't consider CMA memory as free

As CMA memory can only be used for Movable allocations,
Android lowmemkiller shouldn't consider this as free memory
for lowmem kill decisions.  If it considered as free memory,
It can delay the killing of apps and lead to slowness of
system as memory allocations start waiting for kswap
daemon to free up the memory.

deinitialisation:
- If two channel initialisations were running concurrently for

gave an uninitialised channel to the second requester

video: tegra: host: Fix debug dump

Currently the debug dump routine is vulnerable against tricky races.
As normal operation is more important than getting the full dump
always, this patch reworks mutex usage in debug dump routine:

 - lock the channel list is now before going through channels. This
   ensures that channel states remain valid even if some of the
   channels were finished during dump.
 - this patch modifies mutex_lock() calls to mutex_trylock() calls.
   This ensures that the function call cannot block.

Incremented nvmap_handle ref count in utility function
nvmap_get_id_from_dmabuf_fd() before the function release reference
to dma buffer. This is required to avoid race conditions in nvmap

4 years agocpufreq: ondemand: Change the calculation of target frequency
Stratos Karafotis [Wed, 5 Jun 2013 16:01:25 +0000]
cpufreq: ondemand: Change the calculation of target frequency

The ondemand governor calculates load in terms of frequency and
increases it only if load_freq is greater than up_threshold
multiplied by the current or average frequency.  This appears to
produce oscillations of frequency between min and max because,
for example, a relatively small load can easily saturate minimum
frequency and lead the CPU to the max.  Then, it will decrease
back to the min due to small load_freq.

Change the calculation method of load and target frequency on the
basis of the following two observations:

 - Load computation should not depend on the current or average
   measured frequency.  For example, absolute load of 80% at 100MHz
   is not necessarily equivalent to 8% at 1000MHz in the next
   sampling interval.

 - It should be possible to increase the target frequency to any
   value present in the frequency table proportional to the absolute
   load, rather than to the max only, so that:

   Target frequency = C * load

   where we take C = policy->cpuinfo.max_freq / 100.

Tested on Intel i7-3770 CPU @ 3.40GHz and on Quad core 1500MHz Krait.
Phoronix benchmark of Linux Kernel Compilation 3.1 test shows an
increase ~1.5% in performance. cpufreq_stats (time_in_state) shows
that middle frequencies are used more, with this patch.  Highest
and lowest frequencies were used less by ~9%.

[rjw: We have run multiple other tests on kernels with this
 change applied and in the vast majority of cases it turns out
 that the resulting performance improvement also leads to reduced
 consumption of energy.  The change is additionally justified by
 the overall simplification of the code in question.]

4 years agomedia: platform: tegra: support 64 bit user code
Charlie Huang [Fri, 11 Jul 2014 23:19:32 +0000]
media: platform: tegra: support 64 bit user code

Since the user space code may works in either 32 or 64 bit mode,
attentions should be taken while passing pointers from user space to
the kernel. In this case, the p_value of struct nvc_param and
power_on/power_off of struct virtual_device received from the user
space should be handled properly.

The solution is to create a set of 32 bit version of structures
nvc_param and virtual_device along with some dedicated 32 bit mode
ioctl commands, then in the ioctl functions, the 32 bit user mode
access will be handled separately.
