arm ds-5 v5.9版本更新

this is a summary of the new features and other major changes in this release:

l  arm compiler toolchain: updated to 5.01u2 release for latest bug fixes

l  arm streamline: timeline filtering per process selection

l  arm streamline: timeline process pane can be configured to display gpu (graphics processor) and vpu (vertex processor) heat map

l  arm streamline: visualization of mali gpu vertex and fragment processors trace activity

l  arm streamline: dvfs clock frequency is displayed in the timeline chart

l  arm streamline: support for all performance counters on qualcomm scorpion processors (for example msm8660)

l  arm streamline: support for the architecturally compliant counters on qualcomm krait processors (for example msm8960)

l  arm streamline: current, voltage and power usage can be analyzed using the energy probe hardware unit (available to purchase separately)

l  arm streamline: added onlining/offlining support for perf inside gator

l  arm streamline: gator uses perf hal on linux versions 3.0 and later

l  arm streamline: includes gator_v8

l  dstream/rvi: new 4.6 version of firmware included

l  ds-5: linux edition is renamed to basic edition

l  ds-5: installation now includes flexnet 11 binaries

l  ds-5 debugger: added support for debugging linux symmetric multiprocessing (smp) systems

l  ds-5 debugger: debug control view provides separate visibility of active (currently scheduled) threads and all threads

l  ds-5 debugger: debug control view and command line indicate the power state of each core

l  ds-5 debugger: when performing linux kernel debug, the list of threads that is printed when stopping now only includes the active (currently scheduled) threads; use info threads to list all the threads

l  ds-5 debugger: new address spaces ahb: and apb: added for direct memory access via a coresight debug access port

l  ds-5 debugger: memory can be accessed whilst the target is running (subject to the target and address spaces supporting this)

l  ds-5 debugger: memory can be filled using new fill memory dialog in eclipse and using memory fill from the command line

l  ds-5 debugger: debugger can connect to vstream (available for purchase separately) to debug on rtl simulators and hardware emulators

l  ds-5 debugger: device support extended to include: arm versatile express v2p cortex-a15, arm versatile express with cortex-a15 neon soft macrocell model, arm versatile express with cortex-r5x2, arm versatile express cortex-a15x4 cortexa7x4 rtsm, calao systems snowball board, nvidia tegra 3, pandaboard es, st-ericsson ap9500, ti am3352/4/6/7/8/9 / omap 4460 and xilinx zynq-7000 epp zc702

l  eclipse: elf content editor now displays segment information in a separate tab

l  examples: new example added to demonstrate trustzone debugging on versatile express a9x4 board: trustzone

l  examples: new example added to demonstrate symmetric multiprocessing (smp) bare-metal debug on cortex-a15 mpcore: smp_primes_a15x2-coretile

l  examples: new example added to demonstrate symmetric multiprocessing (smp) bare-metal debug on snowball: fireworks_snowball

l  examples: new instrumented c code example added to demonstrate instrumented arm streamline bookmark, text, and visual annotations: streamline_annotate

l  examples: new example jython script added in ds-5 debugger: jython_hash

l  examples: bare-metal start-up code added for the cortex-a15 mpcore processor: startup_cortex-a15mpcore

l  examples: kernel module debug example now has a generic makefile, to build it against any kernel with user-supplied dependencies, for example, for use on snowball
