EPIA-M HW graphics slow under linuxbios
Hi, I have taken freebios from CVS and applied the patch from here http://www.clustermatic.org/pipermail/linuxbios/2003-July/004046.html to enable VGA. It works perfect. Exactly what I need. The major problem with such a build is that directfb( it uses HW accelaration extensively ) works 2 times slower. Even though it still uses it as without acceleration it runs 10 times slower... I'm wondering what could cause such a slow performance ? Does anyone have any suggestions ? ( It seems all other pure memory/disk programs are not affected ) Dmitry/
well we obviously have more to do here. Somebody want to do some register dumps and see what it could be? I have no EPIA-M. Work on bios emulation continues ... ron
Do you have a script I can run ? Dmitry/ ----- Original Message ----- From: "ron minnich" <rminnich@lanl.gov> To: "Dmitry Borisov" <jbors@mail.ru> Cc: <linuxbios@clustermatic.org> Sent: Wednesday, January 28, 2004 8:32 PM Subject: Re: EPIA-M HW graphics slow under linuxbios

just lspci -xxx in linuxbios and standard bios. ron

Just guessing ... Maybe an MTRR entry is missing? Does the epia connect it's graphics with an (AGP) bridge? Maybe the bridge is not at full speed? Stefan -- Stefan Reinauer, SUSE LINUX AG Teamleader Architecture Development
How to verify what you're saying about AGP bridge ? Are ther any utilities or something ? Let me know if I can do some research and where to look.
