android: compilation failure with new version of svn

2012-05-23T13:55:46+00:00

The line setting SVN_REV assumes "svnversion" will report either the svn revision of the directory or "exported". This assumption is no longer true for subversion 1.7.4, which reports "Unversioned directory" instead of "exported", causing the build to fail (gcc -DSVN_REV=Unversioned directory) Signed-off-by: Bernhard Rosenkranzer Submitted-by: Mathieu Poirier

snowball: android: mali: Disable profiling of Mali L2 cache

2012-05-22T09:04:33+00:00

When connecting the ARM Streamline Performance Analyzer to Snowball Android this will cause a board lock-up if the screen is static (Bug #961962). The cause of this appears to be a know issue with reading the L2 cache performance counters whilst the hardware block is powered down. As the current code is written to access these counters even when they have not been explicitly selected then this issue prevents Streamline being used reliably for any purpose. To workaround this bug, this patch disables support for the L2 cache counters in Mali. This has no effect on the operation of the cache. Signed-off-by: Jon Medhurst

snowball: android: mali: Add Streamline Support for Mali DDK

2012-05-22T09:04:33+00:00

ARM's Streamline Performance Analyzer now supports Mali graphics. This requires support from the Mali kernel module which this patch adds. These changes were delivered by ARM Ltd in a patch file called: r2p3-01rel0_gpl_driver_streamline_support.patch that came with a README.txt which included the following... BUILDING THE DRIVER The driver can be built as normal. Profiling instrumentation is enabled by default by the patch. To disable it, use USING_PROFILING=0 in your build command. To revert to the old-style profiling code, use USING_INTERNAL_PROFILING=1 this option will disable the Streamline profiling support. KNOWN ISSUES * Attempting to read L2 cache counters when the hardware block is powered down could potentially lead to a hang due to a lack of locking. This will be addressed in a future driver update. Signed-off-by: Jon Medhurst
