Yonattan Louise 63e3a4e772 Fix checkpatch issue - ERROR:ELSE_AFTER_BRACE The 'else' statement should be in the same line that the close brace of the 'if' statement. E.g.: if (condition) { do_this(); do_that(); } else { otherwise(); } This commit fixed this kind of error using the following script: #!/bin/bash for file in $(find ./ -name ".[ch]" ! -path "./scripts/" ! -path "./host/src/wrsconfig/"); do if [ ! -h $file ]; then sed -i '/^[ \t]}$/ { :review_next_one_too N s/^$.$\n[ \t]else/\1 else/ /}$/ b review_next_one_too }' $file; fi; done Change-Id: I7e811a572d735fa08e84850055ebbde29eb10e8d Signed-off-by: Yonattan Louise <yonattan.a.louise.mendoza@intel.com>		2016-02-05 20:13:59 -05:00

Title: test_fp_sharing

Description:

This test uses two tasks to independently compute pi, while two other tasks
load and store floating point registers and check for corruption. This tests
the ability of tasks to safely share floating point hardware resources, even
when switching occurs preemptively. (Note that both sets of tests run
concurrently even though they report their progress at different times.)

The demonstration utilizes microkernel resource APIs, timers, semaphores,
round robin scheduling, and floating point support.

Building and Running Project:

This microkernel project outputs to the console.  It can be built and executed
on QEMU as follows:

    make pristine
    make microkernel.qemu
