Adding to a definition
by Programmingkid 17 May '12

17 May '12

Is there a way to add words to the end of a definition? If my word is declared like this: : myword firstWord secondWord ; is there a way to append a word to the end of this word so it looks like this: : myword firstWord secondWord thirdWord ;

MS word
by Programmingkid 30 Apr '12

30 Apr '12

The MS word is suppose to wait a specified amount of milliseconds before allowing a program to continue. Yet when a simple line of code like this is run: "1000 MS ." hi" ", the message is printed immediately. This happens no matter how high the top value on the stack is. Is this a bug or am I missing something?

Author: mcayland Date: Sat Apr 28 15:35:00 2012 New Revision: 1054 URL: http://tracker.coreboot.org/trac/openbios/changeset/1054 Log: SPARC64: Remove majority of the video initialisation hack. Now that we have OFMEM, as long as we have a PCI bus then we can configure the address of the framebuffer automatically without having an architecture-specific hack. The only thing we need to do is override the virtual address from the OFMEM phys == virt default. Similarly we can remove all reference to the video memory variables _vmem and _evmem since the memory is allocated outside of the OpenBIOS image. This commit also fixes another couple of issues: switch video.c to use virtual instead of physical addresses for architectures that require it (the default is the existing behaviour where phys_addr == virt_addr) and also correct the framebuffer size calculation which was also adding the framebuffer start address to size of the framebuffer to be mapped.

This cleans up the OFMEM interface by allowing us to keep all of the architecture-specific code in separate header files; in particular ofmem_sparc32.h and ofmem_sparc64.h. PPC doesn't reference the variables from ofmem.h outside of ofmem.c, so simply redefine them as static variables.

Author: mcayland Date: Sat Apr 28 15:34:42 2012 New Revision: 1049 URL: http://tracker.coreboot.org/trac/openbios/changeset/1049 Log: Rename ofmem_arch_early_map_pages() to ofmem_arch_map_pages(). This OFMEM call does actually map the page for the architectures that require it, so let's change its name so that we now have a symmetrical ofmem_arch_map_pages() and ofmem_arch_unmap_pages() API.
