2006-12-08[PATCH] ioremap balanced with iounmap for drivers/video/offbAmol Lad
ioremap must be balanced by an iounmap and failing to do so can result in a memory leak. Signed-off-by: Amol Lad <amol@verismonetworks.com> Cc: "Antonino A.

2006-11-01[POWERPC] Fix various offb issuesBenjamin Herrenschmidt
This patch fixes a few issues in offb: - A test was inverted causing the palette hack to never work (no device node was passed down to the init function) - Some cards seem to have their assigned-addresses property in a random order, thus we need to try using of_get_pci_address() first, which will fail if it's not a PCI device, and fallback to of_get_address() in that case. of_get_pci_address() properly parsees assigned-addresses to test the BAR number and thus will get it right whatever the order is. - Some cards (like GXT4500) provide a linebytes of 0xffffffff in the device-tree which does no good. This patch handles that by using the screen width when that happens. (Also fixes btext.c while at it). - Add detection of the GXT4500 in addition to the GXT2000 for the palette hacks (we use the same hack, palette is linear in register space at offset 0x6000).

2006-07-31[POWERPC] video & agp: Constify & voidify get_property()Jeremy Kerr
Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powerpc-specific video & agp driver changes. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-07-26[POWERPC] More offb/bootx fixesBenjamin Herrenschmidt
There were still some issues with offb when BootX doesn't provide a proper display node, this fixes them. This also re-instates the palette hacks that were disabled a couple of kernel versions ago when I converted to the new OF parsing, and shuffles some functions around to avoid prototypes.

2006-07-10[PATCH] vt: Remove VT-specific declarations and definitions from tty.hJon Smirl
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h allows all of the framebuffer and VT console drivers to remove their dependency on tty.h.

2006-07-03[POWERPC] Fix various offb and BootX-related issuesBenjamin Herrenschmidt
This patch fixes various issues with offb (the default fbdev used on powerpc when no proper fbdev is supported). It was broken when using BootX under some circumstances and would fail to properly get the framebuffer base address in others.

2006-01-09[PATCH] powerpc: Remove device_node addrs/n_addrBenjamin Herrenschmidt
The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

2005-11-17[PATCH] powerpc: Workaround for offb on 64 bits platformsBenjamin Herrenschmidt
This fixes a problem with offb not parsing addresses properly on 64 bits machines, and thus crashing at boot. The problem is worked around by locating the matching PCI device and using the properly relocated PCI base addresses instead of misparsing the Open Firmware properties.

2005-11-07[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbconAntonino A. Daplas
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for drivers that do not support hardware cursors is redundant. The soft_cursor function is usable by all drivers because it is just a wrapper around fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is moved to the console directory. Thus, drivers that do not support hardware cursors can leave the fb_cursor field blank. For drivers that do, they can fill up this field with their own version. The end result is a smaller code size. And if the framebuffer console is not loaded, module/kernel size is also reduced because the soft_cursor module will also not be loaded.

2005-09-09[PATCH] Separate pci bits out of struct device_nodePaul Mackerras
This patch pulls the PCI-related junk out of struct device_node and puts it in a separate structure, struct pci_dn. The device_node now just has a void * pointer in it, which points to a struct pci_dn for nodes that represent PCI devices. It could potentially be used in future for device-specific data for other sorts of devices, such as virtual I/O devices. Signed-off-by: Paul Mackerras <paulus@samba.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
