Hi,
the 11.08 Android toolchain RC is ready:
https://android-build.linaro.org/builds/~linaro-android/toolchain-4.6-2011.08/#build=6
https://android-build.linaro.org/jenkins/job/linaro-android_toolchain-4.6-2011.08/6/artifact/build/out/android-toolchain-eabi-linaro-4.6-2011.08-6-2011-08-19_20-41-31
Sounds good. Siarhei has just submitted a new patch for implementing
accelerated ISLOW decoding, and he plans to tweak that over the coming
days. Unless anyone sees a reason not to, I would like to release the
official libjpeg-turbo 1.2 beta in September or early October.

HI Bero,
What I did was changing both Os and O2 to O3 in TARGET_linux-arm.mk. I did
not change those O2/Os specified in each module internally. As there may be
a reason for the module itself to specify the optimisation level. I think it
is risky to change those. But I don't think it should be a bi

FSG_NUM_BUFFERS is set to 2 as default.
Usually 2 buffers are enough to establish a good buffering pipeline.
The number may be increased in order to compensate a for bursty VFS
behaviour.

2 buffers.
