* pixelflinger: Provide more scanline shortcut functions.David 'Digit' Turner2011-04-161-40/+842
| | | | | | | | | | | | | | | | | | | This patch adds a dozen more "shortcut" scanline-processing functions to pixel-flingers. All of them avoid using the JIT for the corresponding operation (on ARM), or using the generic and _extremely_ slow 'scanline' function (on x86, where there is no JIT). The shortcuts were selected by running the system under emulation (build full_x86-eng, then launch emulator-x86), and correspond to operations that are in use when using the system's typical UI features. This makes it much more responsive and amenable to testing most applications, at least those that don't use OpenGL ES heavily. Note that HW OpenGLES emulation is under completion and should solve this problem entirely, though is not there yet. Change-Id: I9c73ba21ad158d6cc5532fabe7ed2419e00ecb3f

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces UBFX instruction generation abilities to the Pixelflinger JIT, and also modifies the component extraction function to generate the instruction. The extract function contains defines to prevent generation of UBFX on pre-v7 cores. The JIT itself retains the ability to produce the instruction even on v5/6. This patch only generates UBFX when MOV, AND or BIC can't be used. Based on the TRM, this appears to be faster on A9 than using UBFX in all cases. On startup, Pixelflinger JITs three chunks of code. UBFX improves these as follows: 00000077:03515104_00000000_00000000 (Blends a single colour into an RGB565 buffer.) Before: 27 inst/pixel, After: 24 inst/pixel, Improvement: 12.5% 00000077:03545404_00000A01_00000000 (Blends RGBA8888 texture into an RGB565 buffer using alpha.)

* | | Allow pixelflinger to work when NX (No Execute) is enabled.Nick Kralevich2010-05-072-7/+33
|/ / | | | | | | | | | | | | | | | | | | | | | | | | Instead of allocating memory from the (non executable) heap, allocate memory using mspace and ensure that we use mprotect to mark it as PROT_EXEC. This allows pixelflinger to continue to work even when NX protections are enabled. Testing: Using the ApiDemos market app, verify that Apidemos -> Graphics -> OpenGL ES -> GLSurfaceView works when "adb shell setprop debug.egl.hw 0" is set.

| * Fix LDM addressing mode disassemblyMartyn Capewell2010-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Pixelflinger disassembler does not handle LDM addressing modes correctly, assuming that the P and U bits in the instruction mean the same in both LDM and STM. This results in the disassembler producing sequences like: stmfd r13!, {r4-r11, r14} ... ... ... ldmea r13!, {r4-r11, r14} This small patch fixes it by EORing the P and U bits with the Load/Store bit.

Introducing the UXTB16 instruction allows removal of some masking code, and is beneficial from a pipeline point of view - lots of UXTB16 followed by MUL sequences. Also, further rescheduling and use of SMULWB brings extra performance improvements. * Use UXTB16 in bilinear filtered texturing Uses UXTB16 to extract channels for SIMD operations, rather than creating and ANDing with masks. Saves a register and is faster on A8, as UXTB16 result can feed into first stage of multiply, unlike AND. Also, used SMULWB rather than SMULBB, which allows removal of MOVs used to rescale results. Code has been scheduled for A8 pipeline, specifically aiming to allow multiplies to issue in pipeline 0, for efficient dual issue operation. Testing on SpriteMethodTest (http://code.google.com/p/apps-for-android/) gives 8% improvement (12.7 vs. 13.7 fps.) SMULBB to SMULWB trick could be used in <v6 code path, but this hasn't been implemented.
| * | NEON shortcut for flat colour blending into 16-bitMartyn Capewell2009-12-074-0/+284
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a shortcut for the needs descriptor 00000077:03515104_00000000_00000000. It requires blending a single 32-bit colour value into a 16-bit framebuffer. It's used when fading out the screen, eg. when a modal requester pops-up. The PF JIT produces code for this using 24 instructions/pixel. The NEON implementation requires 2.1 instructions/pixel. Performance hasn't been benchmarked, but the improvement is quite visible. This code has only been tested by inspection of the fading effect described above, when press+holding a finger on the home screen to pop up the Shortcuts/Widgets/Folders/Wallpaper requester. Along with the NEON version, a fallback v5TE implementation is also provided. This ARM version of col32cb16blend is not fully optimised, but is a reasonable implementation, and better than the version produced by the JIT. It is here as a fallback, if NEON is not available.

| | | | | | | | | | | | | | | | | | | | | | | | | | during blending into 8888 buffers when ONE / ONE_MINUS_SRC_ALPHA blending mode was used, the code wasn't saturating the color component. the reason was that this mode is used for premltiplied alpha blending, however, if used with a non premultiplied source, the color component would wrap. unfortunately, this costs 6 extra cycles per pixels, however... "correctness" prevails. this should not impact the UI since it's using h/w acceleration most of the time it also doesn't impact games which should be using h/w GL. This change will slow the emulator down a bit.
