FS-UAE 1.1 Development Series

[FrodeSolheim]

* Use GL_NV_fence extension for display synchronization where available.
* Use GL_APPLE_fence extension for display synchronization where available.
* Some code refactoring for better future portability.
* Fix rendering of scanlines with aspect correction on (overscan).
* Use requested video_format for text rendering and utility textures as well.
* Use smaller texture for text rendering and caching (for now).

Source only for now -build farm not currently running. Linux/nVIDIA users (at least those who compiles themselves) are especially encouraged to test this release, as it should run better than ever, both with and without a compositing manager running.

Compiled and working !

Seem to be a little faster (sysinfo gave me 106x A600 speed before, now 115x)
and in WhichAmiga detected like A1200 (with "SUPER" mode) before, now like A4000.

need to test more to find bugs

Great -Although the point was to improve framerate / display synchronization, this update does free up more CPU time to be spent emulating ;-)

Well, the version works for everyone, but the big improvement should only affect nVIDIA users. But this does not necessarily mean that other users are left behind. The point was that nVIDIA drivers were troublesome to start with because of excessive CPU usage while executing glFinish. Other drivers may not have this problem to begin with.

A similar technique can be used on non-nVIDIA hardware if ARB_sync extension is implemented by the driver, and I plan to support this as well. If you find the text "ARB_sync" in FS-UAE.log for a recent development version, this will probably work for you soon.

"Unfortunately", I only have nVIDIA hardware, so I cannot easily test Linux/ATI performance, for instance (or Intel graphics, etc), but for all I know, it already works perfectly in these cases.

GL_ARB_sync in my log with ATI 5700 HD gpu.

Excellent! Then you can test FS-UAE when I add support for this extension. Whether this will actually improve anything depends on the driver. There is a simple test for this: If

fs-uae [other args] --video-sync=off

uses significantly less CPU (as measured by "top" for example), than

fs-uae [other args] --video-sync=auto

-then the use of GL_ARB_sync should reduce CPU usage in the latter mode to something more like the former.

just attached a real 2.5p ide hard drive to my PC, but fs-uae won't boot on it .. sd-card on usb is ok, but not IDE hard drive.

edit: can boot but fs-uae is changing permission :

info2000@infonux:~$ sudo chmod 777 /dev/sda

info2000@infonux:~$ ls -l /dev/sda
brwxrwxrwx 1 root disk 8, 0 2012-04-19 15:05 /dev/sda

after quitting fs-uae :

info2000@infonux:~$ ls -l /dev/sda
brw-rw---- 1 root disk 8, 0 2012-04-19 15:17 /dev/sda

I searched through the code, but did not find a relevant call to chmod, so I don't think FS-UAE does this. Perhaps some system policy/daemon regularly corrects/resets the mode for security purposes?

You can add your user to the "disk" group (and log out/in again). This way you don't need to have altered permissions.

Try this version:

Version 1.1.7
* Use GL_ARB_sync extension for display synchronization where available.
* Try creating a OpenAL context at 48000 Hz first.

Any ETA to fix the CDROM select problem?!

Thanks Frode, for now I'm at work, tonight I compile the source and let you know the results.

I know this issue is fixed in the WinUAE 2.4.1 betas, but I don't plan to merge code until WinUAE 2.4.1 is released (Perhaps a week away, according to winuae.net).

You can merge filesys.c and isofs.c (and related header file) changes safely. I don't recommend touching other parts just yet

[Speedvicio]

Frode I tested the latest version with support for GL_ARB_sync, memory usage has actually decreased around 85% to 75% (especially with vsync disabled), unfortunately increase the video synchronization problems .

fs-uae crash when launching netsurf (68k)...

[Pyromania]

When I start fs-uae on OS X Lion all it does is bounce up and down.




Then Application Not Responding Error.

This is not working on a i7 MacBook Air. fs-uae works fine on on older iMac.

Send me your i7 macbook air and I'll send you an older one back that'll work with FS-UAE. Problem solved.

PM me for my address

Please post the log file, if it is created (if not, please check if the Mac system log contains anything FS-UAE-related).

Much improved performance with 1.1.7 compared to 1.1.5 on Linux with a GTS450 (drivers = 295.40). Average cpu usage while playing a couple of games (across two 3.2ghz cores and with "sync = vblank") dropped roughly from 65% to 21%.

Just thought you might like to know.

Many thanks for your efforts FS

My Logitech Precision joypad is detected and the direction pad works, but not the fire buttons. Any ideas? I've got rid of USB Overdrive because that was just getting in the way.
