- * Compiling the following simply requires the presence of <linux/pci.c>.

- *

- * This scheme requires that the kernel allow mmap()'ing of a host bridge's I/O

- * and memory spaces through its /proc/bus/pci/BUS/DFN entry.  Which one is

- * determined by a prior ioctl().

- *

- * For the sparc64 port, this means 2.4.12 or later.  For ppc, this

- * functionality is almost, but not quite there yet.  Alpha and other kernel

- * ports to multi-domain architectures still need to implement this.

- *

- * This scheme is also predicated on the use of an IOADDRESS compatible type to

- * designate I/O addresses.  Although IOADDRESS is defined as an unsigned

- * integral type, it is actually the virtual address of, i.e. a pointer to, the

- * I/O port to access.  And so, the inX/outX macros in "compiler.h" need to be

- * #define'd appropriately (as is done on SPARC's).

- *

- * Another requirement to port this scheme to another multi-domain architecture

- * is to add the appropriate entries in the pciControllerSizes array below.

- *

- * TO DO:  Address the deleterious reaction some host bridges have to master

- *         aborts.  This is already done for secondary PCI buses, but not yet

- *         for accesses to primary buses (except for the SPARC port, where

- *         master aborts are avoided during PCI scans).

-     * OK, so much for theory.  Now, let's deal with the >real< world...

-     * The above CRTC settings are precise in theory, except that many, if not

-     * most, VGA clones fail to reset the blanking signal when the character or

-     * line counter reaches [HV]Total.  In this case, the signal is only

-     * unblanked when the counter reaches [HV]BlankEnd (mod 64, 128 or 256 as

-     * the case may be) at the start of the >next< scanline or frame, which

-     * means only part of the screen shows.  This affects how null overscans

-     * are to be implemented on such adapters.

-     *

-     * Henceforth, VGA cores that implement this broken, but unfortunately

-     * common, behaviour are to be designated as KGA's, in honour of Koen

-     * Gadeyne, whose zeal to eliminate overscans (read: fury) set in motion

-     * a series of events that led to the discovery of this problem.

-     *

-     * Some VGA's are KGA's only in the horizontal, or only in the vertical,

-     * some in both, others in neither.  Don't let anyone tell you there is

-     * such a thing as a VGA "standard"...  And, thank the Creator for the fact

-     * that Hilbert spaces are not yet implemented in this industry.

-     *

-     * The following implements a trick suggested by David Dawes.  This sets

-     * [HV]BlankEnd to zero if the blanking interval does not already contain a

-     * 0-point, and decrements it by one otherwise.  In the latter case, this

-     * will produce a left and/or top overscan which the colourmap code will

-     * (still) need to ensure is as close to black as possible.  This will make

-     * the behaviour consistent across all chipsets, while allowing all

-     * chipsets to display the entire screen.  Non-KGA drivers can ignore the

-     * following in their own copy of this code.

+     * OK, so much for theory.  Now, let's deal with the >real< world...
+     *
+     * The above CRTC settings are precise in theory, except that many, if not
+     * most, VGA clones fail to reset the blanking signal when the character or
+     * line counter reaches [HV]Total.  In this case, the signal is only
+     * unblanked when the counter reaches [HV]BlankEnd (mod 64, 128 or 256 as
+     * the case may be) at the start of the >next< scanline or frame, which
+     * means only part of the screen shows.  This affects how null overscans
+     * are to be implemented on such adapters.
+     *
+     * Henceforth, VGA cores that implement this broken, but unfortunately
+     * common, behaviour are to be designated as KGA's, in honour of Koen
+     * Gadeyne, whose zeal to eliminate overscans (read: fury) set in motion
+     * a series of events that led to the discovery of this problem.
+     *
+     * Some VGA's are KGA's only in the horizontal, or only in the vertical,
+     * some in both, others in neither.  Don't let anyone tell you there is
+     * such a thing as a VGA "standard"...  And, thank the Creator for the fact
+     * that Hilbert spaces are not yet implemented in this industry.
+     *
+     * The following implements a trick suggested by David Dawes.  This sets
+     * [HV]BlankEnd to zero if the blanking interval does not already contain a
+     * 0-point, and decrements it by one otherwise.  In the latter case, this
+     * will produce a left and/or top overscan which the colourmap code will
+     * (still) need to ensure is as close to black as possible.  This will make
+     * the behaviour consistent across all chipsets, while allowing all
+     * chipsets to display the entire screen.  Non-KGA drivers can ignore the
+     * following in their own copy of this code.
