PVRTune/SGXPerfServer v1.103

• Added PVRTune and PVRScope inside the SDK packages.
• SGXPerfServer is now called PVRPerfServer.
• TA/3D data in graph views now enabled by default.
• Improved recollection of graph view position, this is mostly of use when changing the number of graphs in the tab.
• Fixed: Android builds of PVRScope could "lose" the last custom marks sent before application shutdown as the connection was not flushed.
• Manual: Updating Tune manual with new images.
• Manual: Fixed a minor number of grammatical errors.

SGXPerfServer/PVRTune v1.103

• The PID Editor window is now full decorated with a close box and is resizable, it also now has a proper title, and finally its default position is now aligned with the left hand side of the main PVRTune window.
• Three counters (SGX task load: TA/3D/2D core) are now available in the Developer build.
• Moved to new descriptions for the counters "SGX task load: 3D core" et al.

SGXPerfServer/PVRTune v1.102

• When attempting to open non existant files/servers, or files/servers of the wrong protocol version, PVRTune now offers to delete them from the "recent" list.

SGXPerfServer/PVRTune v1.101

• Fixed PID and RTData colours, they were indicating everything is shared on old (pre 1.7.17.3949) drivers.

SGXPerfServer/PVRTune v1.99

• The PID editor window is improved; it now has a list of selectable PIDs on the left, and the right hand pane shows content for the selected PID.
• Default PVRTune window size is slightly larger.
• Graphs: Timing data is now less translucent, and to aid visual recognition the render-target and PID wingtip colours are now narrower and more intense than the frame colour.
• Graphs: There is now a horizontal scroll bar, this helps the user with navigation and spatial awareness.
• Graphs: A time axis is now drawn along the bottom of each graph.

SGXPerfServer/PVRTune v1.98

• 2D timeline no longer overlaps TA.

SGXPerfServer/PVRTune v1.97

• PVRTune now refreshes its display much more frequently, giving smoother interaction.

SGXPerfServer/PVRTune v1.96

• Added user-defined counters. PVRScope gains two new API's: pplCountersCreate() and pplCountersUpdate(). These allow an application to define a new set of user defined counters at any point and then submit regular (eg per-frame) samples of their values. Counters are expected to increment and never reset. The counter definitions can be changed while running.
• PVRTune GUI: user marks are now prefixed by the PID they came from.
• SGXPerfServer now checks that PVRScope-enabled applications that connect are using the same protocol version (just like the SGXPerfServer to PVRTune connection.)
• PVRTune protocol ID is now 14; older files can no longer be read.
• Major version will now change when the communications protocol changes; if the major version matches then PVRScope, PVRPerfServer and PVRTune will work together.
• Editable library window now defaults a little larger.
• "Float" editable library items now have a text box as well as a slider bar, and the item name now specifies the min and max values.
• Added file/export processed data option, compiled out by default (ENABLE_SAVE_TIMING).
• SGXPerfServer is now called PVRPerfServer.

SGXPerfServer/PVRTune v1.95

• Fixed a bug that caused event packets without a counter reading (ie 1.3 drivers) to have the wrong size. This incorrect size happened to perfectly consume the following event, meaning 'end' events were sent but not appearing to arrive.
• Improved useability; SGXPerfServer and AppLibs now inform each other when they are closing. AppLibs return to looking for an SGXPerfServer. This means that SGXPerfServer can be restarted without restarting the applications, and that SGXPerfServer can inform PVRTune when applications disconnect. Also SGXPerfServer no longer restarts when there is an error communicating to an AppLib (e.g. one that crashed).
• PVRTune accepts a command-line. Just as in the connect box, specify the server as pvrtune://servername or file://hello.pvrtune. Unspecified protocols assume "file"; this allows PVRTune to be associated with .pvrtune files in Windows.
• PID editor now properly clears itself when disconnecting from SGXPerfServer.
• Added Ctrl+F11 keyboard shortcut for "Save image to..."

SGXPerfServer/PVRTune v1.94

• PID and Frame numbers are now shown per activity.

SGXPerfServer/PVRTune v1.92

• User-defined Marks are now microsecond time-stamped when they are sent, rather than when SGXPerfServer spots them, which improves resolution.

SGXPerfServer/PVRTune v1.91

• SGXPerfServer instances running on the same subnet as PVRTune now show up in a new list on the PVRTune front page. Click to connect, as in the recently used connections list. The PVRTune front-page no longer shows the instructions text.
• Fix: TA and 3D tasks that are interrupted by a HW lockup detection are now rendered in the GUI.
• 3D SPM events are now properly labelled in the GUI when the pointer hovers over them.
• PVRTune now shows the OS, driver name, device name and device revision (all as sent from SGXPerfServer) in the advanced remote settings option.
• SGXPerfServer start-up text now includes the driver device name and revision.
• PVRTune CPU usage counter now greys out on WinCE, as it's not available.
• Reading-rate counters, and the CPU load counter - they were always showing 0 (in the counter table, graphs were fine).
• uKernel detected lockups are now drawn as Marks.
• The Android version of SGXPerfServer will no longer exit if it fails to open the file it has been asked to send data to.
• Added reset option to the Android SGXPerfServer.

PVRScope v1.103

• Library to access HW counters and to set up user defined PVRTune stats. First public release.

What's New in Version 2.9, Release 1

Builds

• Fix for utilities paths so Android projects will build under MacOS.
• Fixed packaging of Builds/Media/iTunesArtwork file for iOS SDKs.
• Updated header files (gl2.h, gl2ext.h, gl2extimg.h, gl2platform.h and khrplatform.h) with most recent version from Khronos registry.

Demos

• OGLESParticles: Fixed some spelling and removed some unused variables.
• OGLES2Water: Switched demo to use standard, z-axis major RGB ordered normal maps from new PVRTexTool. ‘WaterToEyeLength’ varying passed but not used. This was being recomputed. Now fixed. ‘vTmp’ was using wrong coordinates and was not correctly mapping the refraction texture. Fixed culling issue: refraction texture was culling incorrect face. Switched to demo rendering FBOs at screen resolution by default for better quality. Removed unused variable ‘PerturbedUVs’. Added a toggle to the UI to render the water effect at the screen's resolution instead of the resolution defined in the code (this increases the fragment workload, but the effect will look better at higher resolutions). Fixed a bug with half of created shaders not being released.
• OGLESFilmTV, OGLESFiveSphere, OGLESFur and OGLESMouse: Fixed disabling of GL_NORMAL_ARRAY before print3D is flushed.
• OGLES2Skybox2: Fixed VBO for the skybox which was not used.
• OGLES2PhantomMask: Added deleting shaders/program of Background in ReleaseView.
• OGLES2Navigation3D: Changed all textures to use the fast PVRTC compressor.

• OGLES2Bloom: Fixed incorrect intra-texel offset for optimized filtering.
• OGLES2ShadowMapping: Removed unused colour variable from the shaders.
• OGLES2Skinning: Fixed the mesh drawing so the skinless mesh fall-back works.
• OGLES2EdgeDetection: Added releasing shaders and programs in OGLES2EdgeDetection
• OGLES2Bumpmap, OGLESMultitexture, OGLES2PerturbedUVs and OGLES2LevelOfDetail: Switched to use standard, z-axis major RGB ordered normal maps from new PVRTexTool.
• OGLES2RenderToTexture: Modified so it uses a normal FBO if we fail to create a multi-sampled one. Fixed missing extension initialization when using multi-sampling. Moved extension loading into tools code. Added multi-sampled FBO support via extension to OGLES2 version.

PVRTools

• CPVRTHash: Added new module which uses Tiny Encryption Algorithm to generate 32-bit hashes of strings or generic data.
• PVRTDecompress: Added new faster PVRTC decompressor.
• PVRTPrint3D: Added ability to specify Projection and ModelView matrices.
• PVRTArray: New module to handle arrays.
• PVRTModelPOD: Added isLoaded() function to be able to check whether a POD file has been successfully loaded before attempting to use any of its data. CountIndices optimised for triangle strips. Modified to only write out the FPS value to POD files if there is animation data. Changed to use PVRT standard variable types.
• PVRTMat4::Translate and PVRTMat4::Scale overloads added that take PVRTVec3, which call the original 3 float functions.
• PVRTResourceFile: Added the ability to override the file loading functions with your own. Removed the StringPtr helper function as, with the added ability to use your own functions, we can no longer guarantee the data will be null-terminated.
• PVRTMisc: prefix GetPOTHigher/Lower() with PVRT.
• PVRTString: Removed default value for the last argument to CPVRTString function compare to fix ambiguous call error. Added find next/previous occurrence of a string. Added left/right functions to return the left/rightmost 'n' characters in the string.
• PVRTPixelType: Changed PixelType to PVRTPixelType as it clashes with something in the Apple Cocoa APIs. Changed unsigned longs into unsigned ints as unsigned int is 32bit under both 32bit and 64bit (unsigned long is 64bit under 64bit).
• PVRTBoneBatch/PVRTModelPOD: Modified so they constantly use malloc for the bone batches instead of a combination of new and malloc.
• PVRTFixedPointAPI: Removed reference to PVRTFixedPointAPI.h from the WindowsVC2008 project and added PVRTBoneBatch.h.
• PVRTPFXParser: Changed default texture wrap mode to ‘REPEAT’. Changed some variable names in ParseTextureFlags to make it more clear for the user. Added better error checking. Correctly set mipmap default to None/Off. Fixed a bug, now binds a texture before setting the texture properties. Changed random ints in PVRTPFXParser to enums to make code clearer. Re-written texture flag parsing to make it clearer and have better error checking. Added function to look up texture index in Effect block from a given name.
• PVRTString: Added a ‘format’ method.
• PVRTgles2Ext: Added GL_IMG_multisampled_render_to_texture support.
• Fix for CPVRTPFXEffect encapsulation – variables are no longer public and now have accessors.

PVRShell

• Removed the piece of common code that subtracts the start time from the time as PVRShellGetTime should return an incrementing time value measured in milliseconds instead of the time since the app start.
• Added ‘prefLoadFileFunc’ and ‘prefReleaseFileFunc’ enum values for use with PVRShellGet that will retrieve function pointers from the shell allowing you to get external files stored as assets in an Android .apk.
• PVRShellScreenSave() now takes the image resolution; previously it assumed it was the same size as the render target, even though PVRShellScreenCaptureBuffer() let you specify a sub-rect.
• Added pixel replication functionality while saving: One use-case for this is in combination with creating a stream of screenshots with the -c option, in order to make a video where the individual pixels can be discerned.
• PVRShellScreenSave() and PVRShellWriteBMPFile() now take an optional parameter, default value of 1, set this value to higher values to replicate the pixels as they are saved, scaling up the image.
• Added a new option ‘prefCaptureFrameScale’ and command-line option ‘-screenshotscale’ to override the default.
• Linux X11: Fixed a bug with not releasing Atoms allocated with XGetAtoms
• Windows: Added a few missing #ifndef NO_GDI defines around recently added GDI functions.
• Windows: Removed support for the Axim (X50v, X51v) hot keys as they are no longer needed.
• MacOS/iOS: Updated to use mach_absolute_time instead of gettimeofday(). Previously if the user changed the system time, any time based functionality in a program could have odd behaviour. mach_absolute_time will return the number of milliseconds that the system has been on, providing a more stable time function.
• Android: Update so it exits correctly if InitView/InitApplication return false.

PVRTexTool v3.23

• "Fixed" Normal map generation. Output is now somewhat more accurate and is in XYZ-RGB order. To use the old order, simply use the channel swapping methods.

• PVRScope now shares the SGXPerfServer/PVRTune version number. SGXPerfServer no longer prints the PVRScope version number (since it's the same).
• Protocol ID is now 13. This prevents the use of old SGXPerfServer binaries or old saved files from being loaded into PVRTune due to data format changes.
• User-defined Marks are now microsecond time-stamped when they are sent, rather than when SGXPerfServer spots them, which improves resolution.
• Marks are no longer limited to 256 characters.

PVRTune v1.92

• Incompatible data/SGXPerfServer dialog box now says the PVRTune version info in the title, and suggests which version the user should use.
• TA/3D tasks now feature an extra splash of colour; the closest tips of each block (i.e. the bottom of 3D tasks and the top of TA tasks) are now colour coded to indicate the render target in use. Particularly in the case of render-to-texture, this helps identify which TA tasks and 3D tasks are part of the same render within a frame.
• PVRTune now also indicates PID changes via colours in the timing data. The outside tips of each block (i.e. the top of 3D tasks and the bottom of TA tasks) are now colour coded to indicate the PID of the program that submitted the task.
• Just like 'sleep' periods are rendered grey, 'data lost' periods are now shown olive and 'host reset' periods are now shown as red.
• Fixed: file save/load dialog boxes are now modal. Dialog box for finding documentation PDF is now modal.

• Improvement for mouse-hovers over the timing data: PID is now shown over the frame data.
• Improvement for mouse-hovers over the timing data: transfer tasks on the 3D core are now labelled.
• Fixed an issue where PVRTune would link power-ons and indicate in the GUI that the HW was asleep when it clearly was not.
• Added some clamping to keep HUD text on-screen.
• Fixed crash: load file, close file, load file, press 'z' to view all; keyboard accelerator still tried to use old deallocated view.
• 3D SPM events are now properly labelled in the GUI when the pointer hovers over them.
• PVRTune now shows the OS, driver name, device name and device revision (all as sent from SGXPerfServer) in the advanced remote settings option.

SGXPerfServer v1.92

• Added 'periodic=' and '-graphics=' to enable/disable those categories of timing tasks (for use when recording to a file).
• The user can no longer toggle timing data (eg with 't' in console variants); must be set on the command-line or via PVRTune connection.
• SGXPerfServer: added ‘--disable-hwperf’ command-line option, useful if you're running an app that uses PVRScope's HWPerf functionality.
• The Android version of SGXPerfServer will no longer exit if it fails to open the file it has been asked to send data to.
• SGXPerfServer start-up text now includes the driver device name and revision.
