This is the system type of your hardware. A "generic" kernel will

run on any supported Alpha system. However, if you configure a
|
|
|
|
kernel for your specific system, it will be faster and smaller.

The AXPpci33 (aka NoName), is based on the EB66 (includes the Multia
|
|
|
|
UDB). This design was produced by Digital's Technical OEM (TOEM)
|
|
|
|
group. It uses the 21066 processor running at 166MHz or 233MHz. It
|
|
|
|
is a baby-AT size, and runs from a standard PC power supply. It has
|
|
|
|
5 ISA slots and 3 PCI slots (one pair are a shared slot). There are
|
|
|
|
2 versions, with either PS/2 or large DIN connectors for the

keyboard.

ALPHA: support graphics on non-zero PCI domains
This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).
An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses. All other machines have the option set FALSE.
A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device. This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.
A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.
Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.

There are two different types of booting firmware on Alphas: SRM,
|
|
|
|
which is command line driven, and ARC, which uses menus and arrow
|
|
|
|
keys. Details about the Linux/Alpha booting process are contained in
|
|
|
|
the Linux/Alpha FAQ, accessible on the WWW from
|
|
|
|
<http://www.alphalinux.org/>.
|
|
|
|
|
|
|
|
The usual way to load Linux on an Alpha machine is to use MILO
|
|
|
|
(a bootloader that lets you pass command line parameters to the
|
|
|
|
kernel just like lilo does for the x86 architecture) which can be
|
|
|
|
loaded either from ARC or can be installed directly as a permanent
|
|
|
|
firmware replacement from floppy (which requires changing a certain
|
|
|
|
jumper on the motherboard). If you want to do either of these, say N
|
|
|
|
here. If MILO doesn't work on your system (true for Jensen
|
|
|
|
motherboards), you can bypass it altogether and boot Linux directly
|
|
|
|
from an SRM console; say Y here in order to do that. Note that you
|
|
|
|
won't be able to boot from an IDE disk using SRM.
|
|
|
|
|
|
|
|
If unsure, say N.

For example, if one wanted the option of printing verbose

machine check printing was turned off, then one would choose

avoid overflows in kernel/time.c
When the conversion factor between jiffies and milli- or microseconds is
not a single multiply or divide, as for the case of HZ == 300, we currently
do a multiply followed by a divide. The intervening result, however, is
subject to overflows, especially since the fraction is not simplified (for
HZ == 300, we multiply by 300 and divide by 1000).
This is exposed to the user when passing a large timeout to poll(), for
example.
This patch replaces the multiply-divide with a reciprocal multiplication on
32-bit platforms. When the input is an unsigned long, there is no portable
way to do this on 64-bit platforms there is no portable way to do this
since it requires a 128-bit intermediate result (which gcc does support on
64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but
since the output is a 32-bit integer in the cases affected, just simplify
the multiply-divide (*3/10 instead of *300/1000).
The reciprocal multiply used can have off-by-one errors in the upper half
of the valid output range. This could be avoided at the expense of having
to deal with a potential 65-bit intermediate result. Since the intent is
to avoid overflow problems and most of the other time conversions are only
semiexact, the off-by-one errors were considered an acceptable tradeoff.
At Ralf Baechle's suggestion, this version uses a Perl script to compute
the necessary constants. We already have dependencies on Perl for kernel
compiles. This does, however, require the Perl module Math::BigInt, which
is included in the standard Perl distribution starting with version 5.8.0.
In order to support older versions of Perl, include a table of canned
constants in the script itself, and structure the script so that
Math::BigInt isn't required if pulling values from said table.
Running the script requires that the HZ value is available from the
Makefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the
architectures which didn't already have it (alpha, cris, frv, h8300, m32r,
m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or
sh64 architectures, since Paul Mundt has dealt with those separately in the
sh tree.

If you enable this option, a subdirectory inside /proc called

|
|
/proc/srm_environment will give you access to the all important

SRM environment variables (those which have a name) and also

to all others (by their internal number).

SRM is something like a BIOS for Alpha machines. There are some
|
|
|
|
other such BIOSes, like AlphaBIOS, which this driver cannot
|
|
|
|
support (hey, that's not SRM!).
|
|
|
|
|
|
|
|
Despite the fact that this driver doesn't work on all Alphas (but
|
|
|
|
only on those which have SRM as their firmware), it's save to
|
|
|
|
build it even if your particular machine doesn't know about SRM
|
|
|
|
(or if you intend to compile a generic kernel). It will simply
|
|
|
|
not create those subdirectory in /proc (and give you some warning,
|
|
|
|
of course).
|
|
|
|
|
|
|
|
This driver is also available as a module and will be called
|
|
|
|
srm_env then.

ALPHA: support graphics on non-zero PCI domains
This code replaces earlier and incomplete handling of graphics on non-zero PCI
domains (aka hoses or peer PCI buses).
An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a
kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose
SRM consoles are capable of configuring and handling graphics options on
non-zero hoses. All other machines have the option set FALSE.
A routine, "find_console_vga_hose()", is used to find the graphics device
which the machine's firmware believes is the console device, and it sets a
global (pci_vga_hose) for later use in managing access to the device. This is
called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a
custom version of this routine because of extra complexity.
A routine, "locate_and_init_vga()", is used to find the graphics device and
set a global (pci_vga_hose) for later use in managing access to the device, in
the case where "find_console_vga_hose" has failed.
Various adjustments are made to the ioremap and ioportmap routines for
detecting and translating "legacy" VGA register and memory references to the
real PCI domain.
