[PATCH 0/4] Atari kernel-in-FastRAM patches, take three

[PATCH 0/4] Atari kernel-in-FastRAM patches, take three

[Michael Schmitz]

Geert,

see the following patch series for the hopefully final word on 
the 'make ST-RAM pool accessible for kernels running from FastRAM'
story.                    

ST-RAM pool is allocated from an arch initcall if the kernel runs 
in FastRAM, at which time memory mapping support is up and running
and ioremap works as it should. 

This should make current kernels run again on TTs with insufficent 
ST-RAM but enough TT-RAM to hold the kernel and user data. It does
speed up kernel operations a great deal on Falcon hardware with
FastRAM on accelerators. 

Side effects: rebooting from a kernel in FastRAM will go through a
hard reboot -no idea why. SCSI operations seem to fail sooner than
otherwise on my system (the SCSI patches are not in my atafb-stram
branch). Need to investigate on both accounts.

Please review and apply. 

Cheers,

        Michael

[PATCH 1/4] m68k/atari - stram: alloc ST-RAM pool even if kernel not in ST-RAM

[Michael Schmitz]

With the kernel loaded to FastRAM (TT-RAM), none of the ST-RAM
address range is mapped by init_mem, and ST-RAM is not accessible
through the normal allocation pathways as a result.

Implement ST-RAM pool allocation to be based on physical addresses
always (it already was when the kernel was loaded in ST-RAM).
Return kernel virtual addresses as per normal.

The current test for the kernel residing in ST-RAM always returns
true. Use the bootinfo memory chunk order instead - with the kernel
in FastRAM, ST-RAM (phys. 0x0) is not the first chunk.

In case the kernel is running from FastRAM, delay mapping of ST-RAM
pool until after mem_init.

Provide helper functions for those users of ST-RAM that need
to be aware of the backing physical addresses.

Kudos to Geert for his hints on getting this started.

Please drop this line, as it prints more or less the same as the %pR in the
line above. Also in the other block.

Please use "%lx", and drop the cast to "void *". Also in the other block.

Hi Geert,

will do. Likewise for the external framebuffer case.

I'm still hung up on the SCSI behaviour with current kernels - may
have managed to trash the SCSI disk filesystems or partitions with an
earlier version of these patches.

Cheers,

[PATCH 2/4] m68k/atari - atafb: convert allocation of fb ram to new interface

[Michael Schmitz]

The new atari_stram_alloc interface returns kernel virtual addresses
even if the kernel runs in FastRAM. These addresses are not
guaranteed to be identical with the physical addresses. Since ST-RAM
mappings have not been set up by mem_init, virt_to_phys() and its
cousin do not work and the atari_stram_to_phys() etc. helpers must
be used to determine physical addresses.

fb.fix->smem_start needs physical addresses, fb.par->screen_base
needs virtual addresses. Take care of the virt-to-phys conversion
both on fb init and par changes.

I think real_screen_base should be renamed to e.g. "phys_screen_base",
and changed to "unsigned long", so you can drop the above cast (and a few
more while assigning it to fix->smem_start).

This will also expose that ATAFB_EXT is broken, and what needs to be
done to fix it (follow the chain of casts, phys addresses are unsigned long,
virt addresses are void *).

Thanks!

Thanks, with debug=par early printk is working.  So the problem is that
kernel-in-FastRAM does not solve the kernel-too-big/FastRAM-too-big
problem, since the page tables for the first node (== FastRAM) memory
must still fit in INIT_MAPPED_SIZE (== 4Mb) - kernel-size.

Andreas.

Andreas,

do we know the size of the first memory chunk early enough in head.S?
Maybe it's time to increase INIT_MAPPED_SIZE at least in cases where
we know that there's more than 4 MB in the first memchunk ...

Cheers,

  Michael

How do you know?  You would have to reimplement the check paging_init
does.

I see - as a heuristic, we can probably assume that the first memchunk is
the relevant one, and especially in the case of FastRAM, also the larger
one.
Does this hold for Amiga/Mac/VME as well? 

Cheers,

People want to run the kernel in the fastest memory chunk, which is typically
also the largest (slow Amiga mainboard memory may be 2 - 16 MiB for
Linux-capable machines, accelerator memory may be larger).

Don't know about Mac, but I have some memories of interleaved banks
and such...

And the chunk the kernel runs from would always be the first chunk 
listed in bootinfo, since that's the one mapped at virtual address zero?

Not sure I've ever seen accelerators or memory upgrades on the Macs that 
I hacked on. 4 MB was sort of plenty in those days.

The kernel always runs in the first chunk.

It may be possible to boot Linux with MacOS running in 24-bit mode, and 
ISTR that this leads to a large number of memory chunks. The Penguin 
documentation says use 32-bit mode (which means installing Mode32 if you 
have old MacOS and old ROMs). The only Mac I have here is running MacOS 
7.6 so I can't test 24-bit mode. You can see the debug output from Penguin 
below.

> but I have some memories of interleaved banks and such...

There are some Mac models with memory controllers that do interleaving. I 
don't know whether interleaving is relevant here. I'd have to consult the 
Penguin source code to know whether it behaves differently on different 
models.

Perhaps you're thinking of this --

    "68020: Don't force kernel into bank A: [optional] This is a special 
    option for the 68020 and MacII owners only. It has to do with the 
    physical arrangement of the memory banks in the MacII ... NOTE: This 
    option has been removed from Penguin 18."

I meant that if you have e.g. 16 MiB of RAM, but it's split in 4
chunks of 4 MiB,
you don't have 8 MiB in the first chunk.

The chunk size would still be 16 MB, perhaps?

(Unless Geert is right and interleaving means multiple small memory
chunks. I doubt Apple engineers would have gone that far.)

Looking at the Penguin source, findRAM() in Source/mmu_support.c sorts the 
boot info memory mappings so that the largest chunk comes first. In 32-bit 
mode, it will probably be the only chunk. Regardless of 24-bit mode or 
32-bit mode, it may not be a 16 MB chunk.

... but not always: Designing Cards & Drivers 3ed. p.28 says, "In the 
Macintosh IIci and the Macintosh IIsi, physical memory is not in one 
contiguous block, so the MMU of the 68030 joins the blocks of physical 
memory to present contiguous logical memory to application software."

I happen to have my crazy PearPC/Mac OS X-booting LC475 still up and 
running with a 7.5.5 system folder on it. I rebooted it into 24-bit mode 
and loading Penguin does give a warning that 32-bit mode works better. 
Attempting to boot generates:

*** Too many memory ranges!!!
Error:
*** setup_ram_mappings() failure - too many mappings

I have a 64mb simm in this LC475; I tried popping it out (leaving me 
with 4mb) and it actually did attempt to unpack the kernel, but there's 
too little memory to do it. I have a bagful of smaller 72-pin simms 
kicking around somewhere; I'll have to dig it out of the closet and try 
it again.

Sadly my IIci is still misbehaving due to bad caps. I do have a working 
840AV here... I believe it should work in 24-bit mode. I don't have any 
older 32-bit unclean Macs of the era when 24-bit was normal to try with 
to see if maybe the memory controller works better.

All I can say here is I ran 2.0-era kernels on a Quadra 840AV which does 
have interleaved RAM way back in the day just fine. I haven't yet gotten 
modern kernels (even the setup that works on the LC475) booting on it 
yet; sadly I'm not much good for coding or debug tracing.

You should be able to get Penguin to list the mappings even when it 
doesn't have room to unpack a kernel.

But there's probably no need: it seems highly likely that you'd see  
no 16 MB chunk on a 16 MB machine in 24-bit mode.

"get_bi_record BI_MEMCHUNK" will return a pointer to the first mem_info
struct.

If the first chunk is at least 8 MiB it should be not that intrusive.
If it isn't, and you have to use multiple chunks, it becomes more complicated.

Yep, that's as far as I got - if I read bootinfo.h right, this will need 
to have an offset of 12 bytes added to get to the size member, correct?

My reasoning exactly - if the first chunk is the smaller one, the page 
tables shouldn't get too big anyway. If it's the larger one, multiple 
chunks are not possible anyway (at least on Atari) due to the 
discontigmem constraint. Either way, 8 MB should be safe if present.

What size FastRAM did precipitate that bug for you, Andreas?

Nope, only 4. A0 points to the bootinfo record payload, which is of
type struct mem_info * in this case:

        movew   %a0@(BIR_SIZE),%d0
        lea     %a0@(BIR_DATA),%a0

Right - should have read on to find the get_bi_record defs.

While poking around in head.S, I came across a comment that stated the 
second page at the start of the kernel is used for the kernel page dir - 
that is the second page of virtual address space (FastRAM, in the case 
we care about here), not physcial address space, right?

Still wondering why the kernel in FastRAM won't reboot cleanly...

The kernel is loaded in the second page of RAM. Initially, this page just
contains a few branches and the bootinfo versions. The code jumps to
_start, and the second page is reused for the kernel page dir:

ENTRY(_stext)
        bras    1f      /* Jump over bootinfo version numbers */
        .long   BOOTINFOV_MAGIC
        .long   MACH_AMIGA, AMIGA_BOOTI_VERSION

It's the combination of kernel size and FastRAM setting that matters.

You can easily watch it by adding the bootmem_debug kernel parameter.
