8de7408125 [mips]: Don't hard-code PHYS_AVAIL_ENTRIES. 2015-11-22 02:40:19 +00:00
adrian
b5c03ef320 mips: teach the malta platform about extended memory.
Extended memory here is "physical memory above 256MB".
"memsize" in the environment only grows to 256MB; "ememsize" is the entire
memory range.  Extended memory shows up at physical address 0x90000000.

This allows for malta64 VMs to be created with > 256MB RAM, all the way
up to 2GB RAM.

Tested:

* qemu-devel package; qemu-system-mips64 -m 2048 (and -m 256 to test the
  no-ememsize case.)

TODO:

* testing mips32 with > 256MB RAM.

95f13176f5 Add domain support to PCI bus allocation
When the system has more than a single PCI domain, the bus numbers
are not unique, thus they cannot be used for "pci" device numbering.
Change bus numbers to -1 (i.e. to-be-determined automatically)
wherever the code did not care about domains.

44c01df173 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

most kernels before FreeBSD 9.0.  Remove such modules and respective kernel
options: atadisk, ataraid, atapicd, atapifd, atapist, atapicam.  Remove the
atacontrol utility and some man pages.  Remove useless now options ATA_CAM.

195d122172 o) Use ABI, not ISA_* options, to determine whether to compile bits if libkern
required for the ABI the kernel is being built for.
   XXX This is implemented in a kind-of nasty way that involves including source
       files, but it's still an improvement.
o) Retire ISA_* options since they're unused and were always wrong.

ac2071063e Remove platform APIs which are not used by any code and which had only stub
implementations or no implementation on all platforms.

Some of these functions might be good ideas, but their semantics were unclear
given the lack of implementation, and an unlucky porter could be fooled into
trying to implement them or, worse, being baffled when something like
platform_trap_enter() failed to be called.

17e14c6132 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

2d5817167b The i8259 controller is initialized incorrectly on MALTA. It writes
mask bits to control register and control bits to mask register.

The former causes ICW1_RESET|ICW1_LTIM combination to be written to
control register, which on QEMU results in "level sensitive irq not
supported" error.

512a6cd715 Switch the GENERIC kernels for all architectures to the new CAM-based ATA
stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.

Does 4 things:
1) Adds future RMI directories
2) Places intr_machdep.c in specfic files.arch pointing to the generic
   intr_machdep.c.  This allows us to have an architecture dependant
   intr_machdep.c (which we will need for RMI) in the machine specific
   directory
3) removes intr_machdep.c from files.mips
4) Adds some TARGET_XLR_XLS ifdef's for the machine specific intra_machdep.h. We
   may need to look at finding a better place to put this. But first I want to
   get this thing compiling.

Use FreeBSD/arm approach for handling bus space access: space tag is a pointer
to bus_space structure that defines access methods and hence every bus can
define own accessors. Default space is mips_bus_space_generic. It's a simple
interface to physical memory, values are read with regard to host system
byte order.

63f02baf0e As discussed on IRC and at BSDcan, move the mips32/* directories up a
