| H A D | sc_machdep.c | diff 146480 Sat May 21 20:38:26 MDT 2005 marius o creator(4): - Use register macros instead of magic values in the code. [1] - Check the return values of OF_getprop() and other stuff that actually can fail. - Let the unimplemented video driver methods return ENODEV rather than 0 so other code isn't tricked into thinking a certain operation was successfull. In case of e.g. the video driver creator_ioctl() this caused vidcontrol(1) to return random garbage information. Remove the TODO macros in the unimplemented video driver methods which did a printf("%s: unimplemented\n", __func__). Under certain circumstances these managed to invoke a printf() when a low-level console device wasn't attached, yet, causing a Fast Data Access MMU Miss. These macros were only really usefull for development anyway. - Set the struct video_adapter and struct video_info va_flags and vi_flags etc. as appropriate. - In creator_configure() don't rely on hitting the node which is the chosen console device first when searching the OFW tree for adapters compatible with this driver. Instead just check whether the chosen console device is a viable target for this driver. Targets that are not the console (including additional cards in multi-head configs) will be attached through creator_upa_attach(). I think this how the code in creator_configure() was actually meant to work. Honour the VIO_PROBE_ONLY flag and don't initialise and register the console device twice when creator_configure() is called a second time during sc_probe_unit(). Let creator_configure() return the number of the found adapters, i.e. 1 in case probing succeeds, as it's expected. The return values of video adapter configure functions however currently aren't checked so this doesn't make a difference at the moment. - In creator_upa_attach() don't rely on probing and attaching the adapter which is the console first, in case there are multiple adpaters and one of them is the console this could lead into using the video adapter unit 0 twice. - Make the check for DACs with inverted cursor control a bit more precise and actually honour that information when turning the cursor on or off. Add a helper function creator_cursor_enable() for this in order to keep code duplication low. [1] - Don't bother with faking a hardware cursor in case a device is the console. Apparently this was meant to start kernel output right after where the firmware left. In general this isn't worth the fuzz and also had no real effect as creator_set_mode() did clear the screen in any case, not just in case a device was not the console. - Implement creator_fill_rect() and use it to actually blank the display in creator_blank_display() when the mode is V_DISPLAY_BLANK, moving blanking the display out of creator_set_mode(). Use it also to implement creator_set_border() so the border can be re-drawn when switching to a VTY from X, exiting X, etc. (which leaves us with a black border most of the time). - Implement the video driver creator_ioctl(), moving the implementation of the IOCTL interface from the fbN CDEV version of creator_ioctl() into the video driver version and use the latter to implement the former. Use fb_commonioctl() to handle most of the FBIO IOCTLs. This gives programs like vidcontrol(1) which use the video driver creator_ioctl() a chance of working. Implement turning off the cursor via the FBIOSCURSOR IOCTL, which Xorg uses to in order to inform the OS that it's taking over the cursor. In creator_putm() check whether the cursor is enabled and (re-)install it if necessary, moving installing the cursor out of creator_init() and into a helper function creator_cursor_install(). This fixes the missing mouse pointer when switching to a VTY from X, exiting X, etc. - Some clean-up (remove unused/useless code, etc.). o sparc64/creator/creator_upa.c / sparc64/sparc64/sc_machdep.c: - Attach syscons(4) as an own pseudo-device on the nexus rather than directly in creator_upa_attach(), similiar to attaching syscons(4) as a pseudo-device on isa(4) on other archs. This makes it a whole lot easier to do the right thing in multi-head configs, especially with different types of graphics adapters. [2] - Set SC_AUTODETECT_KBD by default so USB keyboards work out of the box. [2] Based on/obtained from: Xorg 'ffb' driver [1] Based on/obtained from: FreeBSD/powerpc [2] |
