Actually no excuse for the top post. I see. I like the idea of making sane memory allocation. When I ''fused'' Xspice I took what I thought was was simplest. I think you can replace mspace with malloc. There is no api to disable the address translation we do (i.e. memslots) but it's already equallity. I can't think of any other complication. Yes, the framebuffer is one allocation but it can be changed on every create primary, before it actually and after the destroy primary, with realloc. Maybe even the address can be changed, I think it could, but realloc takes care of that. I guess that has some cost though.
Hmm. Well, I just tried the brute force:
#define mspace_malloc(m,b) malloc(b)
#define mspace_free(m,mem) free(mem)
in qxl_mem.c and my very basic tests seemed to function.
So I guess that suggests I should explore that a little bit further :-/.
For the non vdagent case, we'll still need to have an initial frame
buffer size, so that configuration option is likely to make sense
regardless. Given that, I think I'll go ahead and resubmit this patch.
Cheers,
Jeremy
