Jayant: Per Ian's comment, you can modify xen/arch/x86/setup.c where the hypervisor/dom0 commandline gets parsed.. I think.. Something like.. Vga = 791 (16-bit 1024x768) //// void __init __start_xen(multiboot_info_t *mbi) { char __cmdline[] = "", *cmdline = __cmdline; ..... /* Create initial domain 0. */ dom0 = domain_create(0, 0); if ( (dom0 == NULL) || (alloc_vcpu(dom0, 0, 0) == NULL) ) panic("Error creating domain 0\n"); dom0->is_privileged = 1; /* Post-create hook sets security label. */ acm_post_domain0_create(dom0->domain_id); /* Grab the DOM0 command line. */ cmdline = (char *)(mod[0].string ? __va(mod[0].string) : NULL); if ( cmdline != NULL ) { parse_vga_commandline(..); } ..... } void parse_vga_commandline(..) { init_vga_mode(); } void Init_vga_mode() { // your code.. // detect the card, query BIOS and sets up best possible mode } //// Thanks. -Kaushik -----Original Message----- From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Ian Pratt Sent: Monday, May 07, 2007 1:14 PM To: ron minnich; Jayant Mangalampalli Cc: xen-devel@xxxxxxxxxxxxxxxxxxx Subject: RE: [Xen-devel] vesafb > It is pretty easy, I sent sample code to Ian, if somebody can show me > how they want it to look in Xen, i.e. where the function gets called > and all that, I guess I can try to put it in -unstable. I think we want to parse the dom0 kernel's command line looking for a 'vga=' parameter, and if present, setup the appropriate vesa mode just before un-pausing the newly created dom0.
