Yonattan Louise d85179a0cb Fix spaces after #ifdef This commit deletes the exceeded spaces after #ifdef declaration on the line that the checkpatch script mark as having the SPACING error in order to complay with the defined coding style. The script used to perform this fixes was: checkpatch_script="$VXMICRO_BASE/scripts/checkpatch.pl --mailback --no-tree -f --emacs --summary-file --show-types --ignore BRACES,PRINTK_WITHOUT_KERN_LEVEL,SPLIT_STRING --max-line-length=100 " cd $VXMICRO_BASE; for file in $(find ./ -name ".[ch]" ! -path "./scripts/" ! -path "./host/src/wrsconfig/"); do for line in $(eval $checkpatch_script $file \| grep "ERROR:SPACING: exactly one space required after that #ifdef" \| cut -d":" -f2) do sed -i -r -e ''$line' { s/^#ifdef[ \t]/#ifdef /g }' $file; done; done; Signed-off-by: Yonattan Louise <yonattan.a.louise.mendoza@intel.com> Change-Id: Ic9bb67243f91fa3b5aca6288b306f9b4e8c816fe Signed-off-by: Anas Nashif <anas.nashif@intel.com>		2016-02-05 20:13:33 -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

If executing on Simics, substitute 'simics' for 'qemu' in the command line.
