Application:WarthogKernel

The warthog series of kernels are the kernels intended to explore performance and benchmarking in a stable manner. It will also cherry-pick patches as needed from sbromwich and unixpsycho kernels.

The kernels are only available at http://ipkg.preware.org/feeds/webos-kernels/testing/1.4.1.1/ and can be added using any standard package manager in the standard format (deducing this is left as an exercise for the reader).

Patches applied for 1.4.1-49

• Some makefile housekeeping
• Enabled all TCP congestion algorithms, CPU governors and IO schedulers.
• Testers wanted to help determine optimal configurations. If interested, join #webos-internals IRC channel on Freenode.

Patches applied for 1.4.1-46

• Revised compcache makefile gcc flags
• Initial pixi build. Feedback wanted.

Patches applied for 1.4.1-43

• Compcache included
• Using 2007q3 toolchain
• Use -Os -mtune=cortex-a8 -mcpu=cortex-a8 -march=armv7-a for kernel compile

This makes things about 6% faster @ 500Mhz. YMMV.

Warnings (THIS IS A TESTING KERNEL)

• This kernel may be less stable than Uber-Kernel although stability is still a key target.
• This kernel will only live in testing (meaning, no crying if this kernel eats your phone). Data and knowledge gleaned from this kernel will migrate to UK over time.
• Out of the testing kernels, warthog will most likely be the closest to uber-kernel. That is, it is intended to be less bleeding edge.

Notes

Just a scratchpad for now.
