#8457: Blank screen after boot on Radeon Mobility 4670 HD ------------------------------------------+---------------------------- Reporter: kvark | Owner: kallisti5 Type: bug | Status: new Priority: normal | Milestone: R1 Component: Drivers/Graphics/radeon_hd | Version: R1/Development Resolution: | Keywords: blank radeon Blocked By: | Blocking: 7662 Has a Patch: 1 | Platform: x86 ------------------------------------------+---------------------------- Comment (by kvark): Thanks kallisti5, I'll test it in a couple of hours. I'm still convinced the pitch is not passed correctly though: Write32(CRT, regs->grphPitch, widthAligned); Shouldn't it look like that instead?: Write32(CRT, regs->grphPitch, widthAligned * bytesPerPixel); Also, the pitchMask computation should be changed to match this one: http://kerneldox.net/kdox-linux/d2/db3/radeon__fb_8c.html (look for radeon_align_pitch()) With this code it would produce widthAligned==1408, exactly like on DRM. -- Ticket URL: <http://dev.haiku-os.org/ticket/8457#comment:50> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
