This patchset modifies SeaBIOS source code to be able to build a firmware for the PA-RISC CPU architecture. This firmware can then be used to boot a virtual PA-RISC machine with PA-Linux and HP/UX on QEMU.
Where possible existing SeaBIOS drivers and infrastructure is reused. Since PA-RISC is native 32/64-Bit, the various segment accessors are not needed and replaced by simple variable accesses.

This patch adds or adjust the existing accessors to the various data areas in a x86 BIOS for usage with a PA-RISC BIOS.
On PA-RISC the x86 areas are emulated as normal variables, stored in normal RAM and can be accessed directly.
GET_IVT() and SET_IVT() are emulated by a static ivt_table[] array.
Introduce a get_bda_ptr() inline function to return the address of the Bios Data Area (BDA).
GET_BDA() and SET_BDA() are used to directly access variables from the BDA.
GET_GLOBAL() is used to access variables directly.

SeaBIOS until now only supported the little-endian x86 platform. PA-RISC is big endian, so add the necessary conversion functions depending on the architecture.

On x86 I/O ports are located below address 0x4000, while on PA-RISC I/O ports are allowed in the whole 32/64 bit address space.
So, introduce a portaddr_t typedef which defaults to the current u16 type on x86 and to unsigned long on PA-RISC.

The cdbcmd pointer given to scsi_fill_cmd() can point to an unaligned address. On x86 writing a 64-bit value to an unaligned address will succeed, while on PA-RISC the machine will stop with an unaligned access error (esp. since the fault handlers are not implemented in the firmware).
Work around that issue by using a temporary variable and copy it to the destination when finished.

The lsi-scsi driver expects the SCSI script in little-endian format. Do this conversion on PA-RISC (which is big-endian). On x86 this conversion will be optimized away.

Add the IO-Ports for the PCI bus on PA-RISC. The PCI bus is little-endian on x86 and PA-RISC, so add the necessary conversions for PA-RISC.

On x86 mremap() is used to provide malloc'ed memory. This can't be used on PA-RISC, so provide an own malloc() implementation. Since PA-RISC is fully 32-/64-bit use "unsigned long" instead of "u32".

This patchset modifies SeaBIOS source code to be able to build a firmware for the PA-RISC CPU architecture. This firmware can then be used to boot a virtual PA-RISC machine with PA-Linux and HP/UX on QEMU.
Where possible existing SeaBIOS drivers and infrastructure is reused. Since PA-RISC is native 32/64-Bit, the various segment accessors are not needed and replaced by simple variable accesses.
Btw, the whole patchset can be pulled on top of seabios master tree from:

Thanks.
My main high-level feedback is that this patch series has too many #ifdefs in it. That is, if we want to integrate the code, we'd really need to do the work to fully integrate it. That would mean going through each case where parisc differs from x86 and coming up with alternate code that works well for both architectures. That may, for example, involve compiling different files for different architectures, using different include directives so that different headers get pulled in, and code refactoring in general. Some of this would be possible using runtime checks (eg, if (CONFIG_X86) ), but even that would need to be kept to only those code paths that are architecture specific.
Similarly, there are many cases where parisc has different implementations of similar functionality that isn't architecture specific (eg, malloc implementation, high-level timer implementation, a different boot menu). If the goal is integration then I think we would need to integrate - including the "warts".
I understand that is significantly more work, but I think it would be necessary. My feedback on the patches today is that it feels like there are two notably different SeaBIOS implementations welded together with ifdefs. Unfortunately, that would effectively double the ongoing maintenance costs. I suspect seemingly innocuous changes could break one of the architectures. Or, alternatively, require twice the work for developers to make similar changes in two places. I fear developers would be unlikely to test both architectures on every change and it would be difficult to know which changes impact each architecture.
Separately, on the procedural side, every incremental patch would need to be compilable and runable. This doesn't appear to be the case for this series - as an example, patch 18 pulls in a header file that isn't actually added until patch 27. It's important to order the patches into functional chucks so that "git bisect" works properly, should we encounter a regression. This is particularly important for this patch series given the magnitude of the change.
Cheers, -Kevin

Yes, my goal was not to put additional burden on the SeaBIOS develpers, so I did not expected everyone to do an additional build check if by mistake the parisc target breaks.

Sure.
Overall, thanks a lot for your feedback!!!
But, I'm not clear yet on how to continue. Currently SeaBIOS-parisc is a fork, and I think it's easy to still keep the fork for the time beeing. That way there will not be additional work for the developers.
What I would prefer is if we maybe could work through at least some of the patches and see if we could integrate them (where it makes sense), so that my diff to upstream-seabios can get reduced. Would that be an acceptable way forward?
If yes, I think I need clear guidance, e.g. first of all, is adding a CONFIG_X86 and CONFIG_PARISC config option (patch #1) in the Kconfig OK ?
What about simplifying the bda accessors (patch #2 and #3, but drop the parisc part there before applying). Same for the patches regarding endianess (e.g. patch #4). Trivial ones like patch #7 which adds some parisc constants? And patch #10 which adds the portaddr_t typedef?
Would you be willing to work walk through the various patches and give specific feedback?
Thanks for your help! Helge

No, I mean that the patch series introduces some code that is different from the X86 seabios code, but does not need to be different. That is, it introduces different versions of some functions that are not architecture specific. I understand introducing different versions of functions that are architectures specific - that's a requirement for supporting a different architecture - but it should not be necessary to introduce a parisc version of a malloc function, for example.

Sure - if there are ways to improve the SeaBIOS code that also make it easier to support parisc then that's fine.
If yes, I think I need clear guidance, e.g. first of all, is adding a CONFIG_X86 and CONFIG_PARISC config option (patch #1) in the Kconfig OK ?
In general, no. It wouldn't make sense for us to maintain code or config options for external code. That increases maintenance costs and is unlikely to succeed in general. (No one will test the config options not used locally.)
What about simplifying the bda accessors (patch #2 and #3, but drop the parisc part there before applying).
We can add accessor functions like get_bda_ptr(). However, patch 2 adds a bunch of ifdefs that don't look right to me - in particular, farvar.h already substitutes the simpler assignments when not in "segment mode", so it should not be necessary to add in additional ifdefs in biosvar.h .
Same for the patches regarding endianess (e.g. patch #4).
We can improve the endianness code, but I'd prefer an approach with less ifdefs. Gcc should have a macro for endianness already, and we should be able to use runtime C code to make the checks (which gcc can optimize at compile time).
Trivial ones like patch #7 which adds some parisc constants?
That has the issue of introducing ifdefs, and I don't think that is a good plan for external code (as mentioned above).
And patch #10 which adds the portaddr_t typedef?
That's a case where I'd just change the io functions to use a u32 universally. I don't think a typedef is needed.
Cheers, -Kevin
