http://www.lxdream.org/news lxdream news and updates Thu, 25 Feb 2010 07:23:52 +0000 http://backend.userland.com/rss092 en The (hopefully last) major refactor of the cdrom host subsystem has finally landed in trunk - this shouldn't be particularly user-visible at this point (unless I've broken something, which is entirely possible), although it does fix a few long-standing bugs that no-one ever ran into. Mostly this is to make ... http://www.lxdream.org/news/archives/152 We're now (finally) up-to-date with everything on the site - let me know if I've inadvertently broken anything. I eventually gave up on the Trac option - the core system is nice enough, but it was going to take far too much work to get the plugins up to standard, ... http://www.lxdream.org/news/archives/150 It's been pointed out to me that lxdream currently lacks mailing lists, and that it might be a good idea to have some. I mean, sure we have the forums, but they aren't really as convenient as email, are they? So since my esteemed webhost actually has mailman setup and ... http://www.lxdream.org/news/archives/146 As of this evening, the public source tree is now being maintained in Mercurial at http://www.lxdream.org/hg/lxdream. The subversion repo will stay up for the immediate future for reference, but won't receive any more updates. So if you're following the development trunk, please install a copy of hg if you don't ... http://www.lxdream.org/news/archives/143 As promised, the 0.9.1 release is now out. It is somewhat faster than 0.9, the core is around 30-40% faster, and MMU performance is nearly an order of magnitude better, but rendering performance is still holding things back overall. There's also (finally) preliminary VMU support for anyone who cares about ... http://www.lxdream.org/news/archives/139 Not much really got done last month, seeing as I was away for nearly all of it, but I did get a few small tidy ups done. The new translation core is definitely on hold now for a while so I can get some other things done - I'll get ... http://www.lxdream.org/news/archives/136 I was distracted by Anthony Green's Moxie blog this last week and a bit, specifically by the bit about qemu gdb support. This seemed like a really good idea, not to mention being fairly simple to implement, so it's in now for both the SH4 and ARM. The actual debug ... http://www.lxdream.org/news/archives/131 There's not going to be a February release as originally scheduled - there's just not enough 'stuff' ready to make it worthwhile in my opinion, and anyone looking for the latest has probably already pulled it from SVN. At the current (depressingly slow) velocity, there may be something releasable in ... http://www.lxdream.org/news/archives/83 I've had some high-level performance numbers kicking around for a while - give or take a few percent they're fairly consistent, at least for the work-loads that I've been profiling. So, expressed as seconds of real time per second of emulated time, the runtime looks something like this on my ... http://www.lxdream.org/news/archives/95 Out of sheer curiousity, I thought it might be worth seeing how icc performs on lxdream - short answer, not too shabby at all. All tests otherwise with the same command options, best of 3 runs: Compiler 5-second core runtime Improvement gcc -O2 3.10s N/A gcc -O2 -fprofile-use 2.96s 4.6% icc -fast 2.96s 4.6% icc -fast -prof-use 2.73s 12% Profile runs using profile generated for the ... http://www.lxdream.org/news/archives/119
