Solaris kmdb support for OpenBIOS SPARC64
by Mark Cave-Ayland
Hi all,
I've been looking at how to enable kmdb support for Solaris OpenBIOS
SPARC64 and it seems that OpenBIOS needs some additional routines in
order for the kernel to load the debugger.
AIUI the kernel makes use of 2 traps for kmdb, for which some searching
on the internet gives the following:
0x17d : kadb enter
0x17e : kadb breakpoint
Indeed if I start Milax with "boot cdrom:a -kdv" then current SVN trunk
will halt because the 0x17d trap currently jumps straight to the bug()
routine. Sadly what OpenBIOS should do is a little more hazy, especially
as I don't think the relevant sun4u parts are in Sun's open-sourced
OpenBOOT.
Currently booting Milax will emit the following error on the console
during boot:
interpret : kmdb_callback %pc f000.0000 ffff.ffff between if exit then
%pc h# 18e9058 x! %npc h# 18e9060 x! %g1 h# 18e8f58 x! %g2 h#
18e8f60 x! %g3 h# 18e8f68 x! %g4 h# 18e8f70 x! %g5 h# 18e8f78 x!
%g6 h# 18e8f80 x! %g7 h# 18e8f88 x! 1 %tstate h# 18e9220 x! 1
%tt h# 18e90e8 x! %tba h# 18e90a8 x! h# 12f6098 set-pc go ;
failed with error ffffffffffffffed
kmdb_callback:interpret: exception -13 caught
interpret ['] kmdb_callback init-debugger-hook failed with error
ffffffffffffffed
Based upon this, my best guess would be that both traps above execute
the init-debugger-hook word which simply copies the current register
sets above on PROM entry somewhere accessible to kmdb, then points the
PC to the debugger entry point and resumes execution causing a jump
straight into kmdb. Does this sound about right?
ATB,
Mark.

QEMU OpenBIOS update
by Mark Cave-Ayland
Hi all,
I've just pushed my outstanding patches for OpenBIOS to SVN trunk and
will probably send a QEMU pull request tomorrow as I'm interested to get
both the OFMEM and TCX patches tested as soon as possible (I should add
that it seems to pass all my tests here, but I know Alex has a more
comprehensive build-bot).
The other patch I have on my immediate radar is Zoltan's bus mastering
patch here:
http://www.openfirmware.info/pipermail/openbios/2014-June/008448.html.
Would anyone have any further objections to applying this after the next
QEMU pull request? It seems reasonable, but I can't say I'm overly
familiar enough with PCI to say this won't break anything. Will a
successful test under SPARC64 be good enough? Thoughts?
ATB,
Mark.

[commit] r1320 - trunk/openbios-devel/drivers
by repository service
Author: mcayland
Date: Wed Sep 24 20:03:55 2014
New Revision: 1320

Log:
tcx.fs: add support for hardware acceleration
This is a tidied version of the patch originally posted to the mailing list by
Olivier DANET <odanet(a)caramail.com>.
- Change a few addresses to match actual hardware
- Remove the "address" property from TCX, because of some almost-bug in NetBSD
when detecting framebuffers (actual TCX has no address property, so it works
by chance on real hardware)
- Add the hardware cursor properties
With this and the corresponding QEMU TCX hardware acceleration patch, the
hardware-assisted NetBSD TCX driver will function under QEMU.

Log:
OFMEM: change ofmem_claim() to always allocate addresses where phys == virt
The wording of the IEEE1275 specification for the CIF claim and release words
contains the following:
claim
IN: [address] virt, size, align
OUT: [address] baseaddr
Allocates size bytes of memory. If align is zero, the allocated range begins
at the virtual address virt.... The range of physical memory and virtual addresses
affected by this operation will be unavailable for subsequent mapping or allocation
operations until freed by release.
release
IN: [address] virt, size
OUT: none
Frees size bytes of physical memory starting at virtual address virt, making that
physical memory and the corresponding range of virtual address space available for
later use. That memory must have been previously allocated by claim.
Even though the claim word mentions virtual addresses, the implication from the
release word mentioning physical memory is that allocations made by claim must
have phys == virt. So change ofmem_claim() to ensure that addresses allocated via
the CIF claim word always have phys == virt.
This fixes a bug in MorphOS boot where different physical and virtual addresses
cause mixed accesses by the bootloader to fail.

Re: [OpenBIOS] [PATCH] SPARC64: configure the Sabre PCI TAS register
by Peter Firmstone
There's a lot of cheap sparc hardware based on sunv T2 coming onto the market, I'd like to use AMD cards that are known to work well with the free radeon driver, but none of them have open firmware support.
I've read that IBM's OpenFirmware did include vga bios emulation.
I think the openBoot firmware at the link is for the T1, Sun also released a later version for the T2 sparc processor, which is still available.
They released their hypervisor code too, I don't know it's portable to other architectures, but it's pretty cool technology.
Thanks,
Peter.

[PATCH] OFMEM: change ofmem_claim() to always allocate addresses where phys == virt
by Mark Cave-Ayland
The wording of the IEEE1275 specification for the CIF claim and release words
contains the following:
claim
IN: [address] virt, size, align
OUT: [address] baseaddr
Allocates size bytes of memory. If align is zero, the allocated range begins
at the virtual address virt.... The range of physical memory and virtual addresses
affected by this operation will be unavailable for subsequent mapping or allocation
operations until freed by release.
release
IN: [address] virt, size
OUT: none
Frees size bytes of physical memory starting at virtual address virt, making that
physical memory and the corresponding range of virtual address space available for
later use. That memory must have been previously allocated by claim.
Even though the claim word mentions virtual addresses, the implication from the
release word mentioning physical memory is that allocations made by claim must
have phys == virt. So change ofmem_claim() to ensure that addresses allocated via
the CIF claim word always have phys == virt.
This fixes a bug in MorphOS boot where different physical and virtual addresses
cause mixed accesses by the bootloader to fail.

[PATCH 1/2] tcx.fs: update reg offsets to use proper register names
by Mark Cave-Ayland
Rather than use numerical offsets, use the proper register names as used in
the QEMU TCX hardware acceleration patch.
