But as there is no standard API defined for DRI ( e.g. creating context/drawable etc), so my question is whoever (vendor) implements their OpenGL implementation for DRI/DRM will they be Mesa compliant?Otherwise, if my program already links to Mesa, then can i use vendor's provided dri.so OR, i have to replace Mesa libGL.so with the vendor provided <hw>_dri.so Regs, Rahaman <TABLE CELLSPACING="0" CELLPADDING="0" WIDTH="100%"> <TR> <TD> </TD> </TR> </TABLE> -----Original Message----- From: Daniel Stone <<A HREF="mailto:Daniel%20Stone%20%3cdaniel@fooishbar.org%3e">daniel@fooishbar.org</A>> To: Rahaman <<A HREF="mailto:Rahaman%20%3cmustaf.here@gmail.com%3e">mustaf.here@gmail.com</A>>i, Cc: Dave Airlie <<A HREF="mailto:Dave%20Airlie%20%3cairlied@gmail.com%3e">airlied@gmail.com</A>>, <A HREF="mailto:xorg@lists.freedesktop.org">xorg@lists.freedesktop.org</A> Subject: Re: Reg: AIGLX architecture & it's difference from DRI Date: Mon, 1 Sep 2008 14:19:36 +0300 <PRE> On Mon, Sep 01, 2008 at 02:10:40PM +0530, Rahaman wrote: > 1>If some one( a vendor) gives me only the OpenGL driver(no DRI/DRM > functionality) implementation, can i use that and build my DRI/DRM > modules i.e. Can i write my own dri.so & drm.so and still use the vendor > provided OpenGL? Excuse me as some of my questions can be abstarct or > some cases invalid,too as i am new to this area :-( If you have the source, then yes, you can write a DRI/DRM driver yourself, given enough time. If you don't have the source, then no. > 3>Can i get a comparison like pros & cons for both the architecture in > different context/use cases? Direct: fast. Indirect: slow.
