[PATCH v2 0/4] Introduce and use absolute_pointer macro

[PATCH v2 0/4] Introduce and use absolute_pointer macro

[Guenter Roeck]

Kernel test builds currently fail for several architectures with error
messages such as the following.

drivers/net/ethernet/i825xx/82596.c: In function 'i82596_probe':
./arch/m68k/include/asm/string.h:72:25: error:
	'__builtin_memcpy' reading 6 bytes from a region of size 0
		[-Werror=stringop-overread]

Such warnings may be reported by gcc 11.x for string and memory operations
on fixed addresses if gcc's builtin functions are used for those
operations.

This patch series introduces absolute_pointer() to fix the problem.
absolute_pointer() disassociates a pointer from its originating symbol
type and context, and thus prevents gcc from making assumptions about
pointers passed to memory operations.

v2: Drop parisc patch (the problem will be solved differently)
    alpha: Move setup.h out of uapi
    Define COMMAND_LINE for alpha as absolute_pointer instead of using
    absolute_pointer on the define.

[PATCH v2 1/4] compiler.h: Introduce absolute_pointer macro

[Guenter Roeck]

absolute_pointer() disassociates a pointer from its originating symbol
type and context. Use it to prevent compiler warnings/errors such as

drivers/net/ethernet/i825xx/82596.c: In function 'i82596_probe':
./arch/m68k/include/asm/string.h:72:25: error:
	'__builtin_memcpy' reading 6 bytes from a region of size 0
		[-Werror=stringop-overread]

Such warnings may be reported by gcc 11.x for string and memory operations
on fixed addresses.

[PATCH v2 3/4] alpha: Move setup.h out of uapi

[Guenter Roeck]

Most of the contents of setup.h have no value for userspace
applications. The file was probably moved to uapi accidentally.

Keep the file in uapi to define the alpha-specific COMMAND_LINE_SIZE.
Move all other defines to arch/alpha/include/asm/setup.h.

I guess we're not worried about "val" being evaluated multiple
times inside RELOC_HIDE(), as this is mainly intended for constants?

No, we are not. It is quite similar to RELOC_HIDE() in that regard.

Ok, I've applied this to my tree.

I note that the physical BOOT_PCB addresses in the alpha setup.h file
might be useful for things like MILO in user space, but since I
couldn't even find MILO sources any more, I couldn't really check.

I suspect alpha is basically on life support and presumably nobody
would ever compile a bootloader anyway, so it's unlikely to matter.

If somebody does find any issues, we'll know better and we can ask
where the user space sources are that might use that alpha setup.h
file.

FWIW, I did find a set of MILO sources. Search for milo-2.2-18.tar.bz2;
it points to a variety of gentoo mirrors.
That version does not reference BOOT_PCB. I thought about removing this
define as well as a couple of other unused defines, but wanted to keep
the changes minimal.

On a side note, we may revive the parisc patch. Helge isn't entirely
happy with the other solution for parisc; it is quite invasive and
touches a total of 19 files if I counted correctly.

Thanks,

Ok, my suggestion to use the linker was not a "do it this way", it
really was just a "maybe alternate approach". So no objections if
absolute_pointer() ends up being the simpler solution.

What other notable issues end up being still live? I sent out that one
patch for sparc, but didn't get any response to it. I'm inclined to
just apply it (the 'struct mdesc_hdr' pointer misuse one).

Oh, I forgot about the qnx4 one. That happens on sparc, possibly
others, but not on x86-64.

I'll go look at that patch too.

Yes, it's a lot simpler and makes backporting patches later much easier.
I'll send a pull request with the updated parisc patch tomorrow.

Ok, I didn't love any of the patches I saw for the qnx4 problem, so I
silenced that warning with a new patch of my own. Like the sparc64
case, the fix is to describe more extensively to the compiler what the
code is actually doing.

I think it ended up making it clearer what is going on to humans too.
Although that may be the old "peeing in the snow" effect - it looks
more understandable to me only because I spent so much time trying to
understand what it does, and then wrote the fix based on that possibly
flawed understanding. So of course I find it more understandable.

Looking at the qnx4 code-base history, I don't think it has gotten any
actual development outside of cleanups in the git history timeframe,
which makes me suspect nobody uses this code.

But hey, maybe it just works so well for the very specialized user base ...

Anyway, I pushed it out. I have a clean "allmodconfig" build on all
the architectures I tested, but I didn't test _that_ many.  sparc64,
arm64, powerpc64.

Lots of dts warnings (which aren't fatal), though. Particularly for
the powerpc64 build.

You mean allmodconfig build failures ? There is still a bunch.
For v5.15-rc1-27-gb7213ffa0e58:

That is a typecast from a pointer to an int, which is then sent to an
i/o port. That driver should probably be disabled for 64-bit builds.

I think everyone uses aboot now as the bootloader on Alpha.  So as

Hey, so if it's actively used, maybe you can answer a question or two
that I have just because I looked at the code..

In particular, the inode number calculation is odd. Is there a reason
for the "-1"? Because iboth the link case and the direct inode case
have it, but t's a _different_ "-1":

For the "inode_entry", it does

                ino = blknum * QNX4_INODES_PER_BLOCK + ix - 1;

but it's worth noting that "ix" is zero-based (index within the
block), so this kind of oddly removes one from a zero-based thing, and
the 'ino' for the very first entry ends up being -1.

Of course, it's possible that the first entry is always empty, but it
does seem a bit odd.

For the "link_info" case, it does

            ino = ( le32_to_cpu(de->link.dl_inode_blk) - 1 ) *
                    QNX4_INODES_PER_BLOCK +
                    de->link.dl_inode_ndx;

so now it takes the _block_ index, and does that "-1" on it, and then
multiplies it by the "entries per block" number, and adds the index.

So now if both are zero, the inode number is -8, not -1.

But all of this matches what the *lookup* code does. It's very odd, though.

But to make it stranger, then in "qnx4_iget()", the calculations all
makes sense. There it just does "take the inode number, and look up
block and index into the block using it".

Very strange and confusing. Because it means that iget() seems to look
up a *different* inode entry than "lookup" and "readdir" actually look
at.

I must be missing something. I obviously didn't touch any of this
logic, I was just doing the "make the type system clearer for the
compiler".

Also, I have to say, since I was looking at compiler output, the
calculations in readdir() are made much worse by the fact that the
dir->pos is a "loff_t". That's signed. And then you use "%" to get the
index within a block. Using '%' instead of bitops is fairly
equivalent, but only for

 (a) unsigned types

 (b) when the divisor is a compile-time power-of-2

In the qnx4 case, (b) is true, but (a) is not.

Not a big deal. But usually, I tell people to avoid '% ENTRIES',
because it really has very different behavior from '& MASK' for signed
numbers.

Naah. I think the Jensen actually had an ISA slot. Came with a
whopping 8MB too, so the ISA DMA should work just fine.

Or maybe it was EISA only? I really don't remember.

It's possible that alpha should get rid of the ISA config option, and
use ISA_BUS instead. That would be the proper config if there aren't
actually any ISA _slots_, and it would disable the 3c515 driver.

But it turns out that the compile error is easy to fix. Just make it
use isa_virt_to_bus(), which that driver does elsewhere anyway.

I have no way - or interest - to test that on real hardware, but I did
check that if I relax the config I can at least build it cleanly on
x86-64 with that change.

It can't make matters worse, and it's the RightThing(tm).

Since Micheal replied about that other alpha issue, maybe he knows
about the ISA slot situation too?

But anyway, 3c515 should compile cleanly again.

David is wrong.

The code here is bogus, and the docs clearly state that the transmit
data is in units of "10ms":

    https://www.linux-ax25.org/wiki/6PACK

and that

    #define SIXP_TXDELAY                    (HZ/4)  /* in 1 s */

is just wrong, and the actual *uses* of that TX timeout seems correct
for that 10ms value:

        mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);

ie that "when" is clearly given in 100ths of a second, aka 10ms (ok,
that's mainly SIXP_SLOTTIME, with SIXP_TXDELAY being used mainly to
transfer the data to the other side).

So from everything I can see, your patch is correct.

Of course, to make things more confusing, the RESYNC_TIMEOUTs are
indeed given in ticks.

I spent too much time looking at this, but I'm going to apply that
patch. I suspect either nobody uses that driver any more, or the
TXDELAY values don't actually much matter, since they have clearly
been wrong and depended on random kernel configs for a long long time.

I think the most common HZ value on x86 tends to be the modern default
of 250Hz, so the old "HZ/4" means that most people got a TXDELAY of
620ms, rather than the traditional expected 250ms.

The fact that this shows up as an actual compile error on alpha is
just random luck, since alpha uses a 1024Hz clock. CONFIG_HZ_1000
isn't impossible on other platforms either, which happens to compile
cleanly, but causes that TXDELAY byte to sent out as 250, for a 2.5Hz
TX delay.

Of course, it is possible that it's the documentation that is wrong,
but considering that the documentation matches the code (see above on
that "((when + 1) * HZ)/100"), and matches the "it doesn't cause
compiler warnings", I think it's pretty clear that your patch is the
correct fix.

Ah, yeah, not really.  I am not familiar with the Jensen hardware,
and have never played around with the EISA slot on the Alphas I do

It's EISA only. I've made some pictures of a somewhat dusty inside of
a Jensen with 4 EISA cards (from bottom to top: SCSI, video, 2x network):

(don't worry about the loose cable on one of the pictures, that's just
my crude RTC battery replacment)

I know the feeling.... So many computers, so little time...
While we're at it, during my vain attempts to get new kernels to boot,
I tried to disable PCI support to make the kernels smaller (after all,
the Jensen has only EISA, so what good would PCI support for?) and
got it to compile with the attached patch (which fixes some warnings,
too). Should apply cleanly to Linus tree.

Enable compile for the Jensen without PCI support.

Ok.

Looking around the config options, there _are_ systems with ISA slots,
but it's not the old Jensen one. It's apparently some evaluation
boards but also the "AlphaPC64" one.

So we do want CONFIG_ISA for alpha, even if not Jensen.

(I forget which alpha I had. For some reason I want to think I had an
EISA machine and probably Jensen. Maybe upgraded to a 164 later?)

Ouch. Without having some kind of bisection, I guess we'll never know.
And I assume it's not really been tested since, so it could be
multiple reasons, including compiler updates causing dodgy code to not
work etc etc.

Can you send me your Jensen config?

I do not see why you should be using that horrible __EXERN_INLINE. It
will cause gcc to sometimes not inline at all, and not generate the
out-of-line body either.

Sometimes that is what you want: you want to generate one single body
of the function, and particularly one that is _different_ from the
inlining case (ie for inlining you want to do the simple thing, for
out-of-line you do something fancier).

But that isn't the case here, so this looks like a workaround for
something else. But this code does end up using preprocessor
concatenation etc, so I might be missing some case.

Considering you can actually put ISA cards, 8 and 16 bit both,
into EISA slots, I’d have assumed so. I don’t understand the
“EISA only” question above.

Oh, it's so long since I had one of those machines I didn't even
remember that EISA took ISA cards too.

But yeah, there are also apparently PCI-based alpha machines with
actual ISA card slots.

Yeah, that patch doesn't work at all with my cross-compiler, and only results in

  alpha-linux-gnu-ld: arch/alpha/kernel/sys_jensen.o:(.ref.data+0x58):
undefined reference to `jensen_ioread8'

because some of those 'extern inline' cases are never instantiated.

I'll look into it, we can make Jensen build again in case somebody
then gets the energy to see what causes it to not boot.

Well, as this was way back in 1995, it was perhaps a Multia? Also
named UDB, a small "booksize" model.

Well, I doubt that bisecting will be practical going that way back.

Sure, attached here. I don't know if it helps - I can't tell you why I
used 4.18-rc5 for it, that was in 2018... Oh man, I am spending too much
time at work...

I was just tinkering with it to get it compiled without warning,
I certainly didn't get the big picture :-/

I ended up hacking something up which was enough to show the build
problems, and then some.

But your config shows _other_ errors with the IO functions, so I guess
I'll need to look at that one too.

There's clearly a reason that Jensen was marked BROKEN in the Kconfig,
the whole situation with the IO accessor functions on that platform is
a disaster.

Oh, and all those games with

   #define __EXTERN_INLINE
   #include <asm/io.h>
   #include <asm/jensen.h>
   #undef  __EXTERN_INLINE

don't actually work, because there's the usual multiple-inclusion
protection on top of asm/jensen.h:

   #ifndef __ALPHA_JENSEN_H
   #define __ALPHA_JENSEN_H

and this include of <asm/jensen.h> is entirely unused, because we
ended up getting the one *without* that empty __EXTERN_INLINE #define
from an earlier include of

  #include <linux/interrupt.h>

that caused asm/io.h and asm/jensen.h to be included earlier.

The *other* machine files know to do their includes at the top of the file.

But then I end up getting

     ERROR: modpost: "__udiv_qrnnd" [lib/mpi/mpi.ko] undefined!

because CONFIG_MATHEMU wasn't set and the crypto stuff wants the MPI code.

So there seems to be other alpha Kconfig issues in there, and they
aren't all actually Jensen-specific.

Oh well. I guess can fix things up, since I did get tthe
cross-compiler environment..

Ok, you shamed me into some tinkering too, and I fixed a couple of
issues with the alpha build.

The whole "pci_iounmap()" mess is not something I solved (you were
cc'd on the email I sent out about that), but I did test a few
different Jensen configurations and fixed a couple of uglies.

So at least _some_ Jensen configurations build cleanly once more, and
I re-enabled JENSEN as a valid machine target.

But if it doesn't boot, it's all fairly moot. And those things are a
pain to debug, and if the last booting kernel was years and years ago,
I don't think it realistically will necessarily ever be fixed.

Oh well. I have an odd love-hate relationship with alpha.

I think it's one of the worst architectures ever designed (memory
ordering is completely broken, and the lack of byte operations in the
original specs were a big reason for the initial problems and eventual
failure).

But at the same time, I really did enjoy it back in the day, and it
_was_ the first port I did, and the first truly integrated kernel
architecture (the original Linux m68k port that preceded it was a
"hack up and replace" job rather than "integrate")

As a side note, I loved the Alpha, too. Compared to the VMS port
I was too often working on in the 90s, having Linux run on it was
a joy, and for years I used my remaining older alpha boxes as
firewalls, trusting in the oddity of the architecture to resist
various and sundry attacks.

I retired the last one well over a decade back.

RIP.

Hi,

Yes, I was able to build a minimal Jensen config without any warning
after pulling today, thanks! I think investing a bit in cleaning up
non-PCI configurations may help as soon as PCIe will be obsoleted
by the next bus system ;-)

The main trouble is that my system has only 64MB of memory and the smallest
kernel image with all drivers I need was about 105MB big. According
to: http://users.bart.nl/~geerten/FAQ-9.html
the Jensen can take up to 128MB of RAM and the required PS/2 SIMMs
with partity are still available on ebay, so I just bought 4x32 MB SIMMs.
After setting CONFIG_CC_OPTIMIZE_FOR_SIZE the kernel image was still
93MB big, but with 128MB I should be able to boot it. Let's see....

I didn't had the money for an Alpha at that time, but as soon as
cheap systems were available on ebay, I took the opportunity. At the
time I bought them, I considered the Miatas (the "Personal Workstations"
from DEC) as quite fast - that must have been around 2004/2006.

My experience is that each port is good for code quality, but I can
only state that for user space applications, not having done much kernel
work,

CU,
Uli

Are you sure you aren't looking at some debug image?

I just tried building something based on your Jensen config (lots of
new questions, you sent your old config from 4.18.0-rc5 time), and I
get

  [torvalds@ryzen linux]$ ll -h arch/alpha/boot/vmlinux*
  -rwxr-xr-x. 1 torvalds torvalds 5.4M Sep 20 11:32 arch/alpha/boot/vmlinux
  -rw-r--r--. 1 torvalds torvalds 2.3M Sep 20 11:32 arch/alpha/boot/vmlinux.gz

so yeah, it's not exactly tiny, but at 5.4MB it's certainly not 105MB.

The "vmlinux" file itself is huge, but that's due to CONFIG_DEBUG_INFO=y.

You can easily disable DEBUG_INFO entirely (or at least do
DEBUG_INFO_REDUCED), and get much smaller files.

With the attached config, the vmlinux file is just 7MB (but the actual
one you boot is that same 5.4M file because it's been stripped).

NOTE! The attached config is basically just the one you sent me, with
"make defconfig" done and DEBUG_INFO removed. It might have drivers
missing, or extraneous code that you don't need because of all the
changes in config variables since that very old one.

It would be very interesting to hear whether this all still boots. I
do think people still occasionally boot-test some other alpha
configurations, but maybe not.

I test on a couple of alpha configurations with some regularity:
Marvel (AlphaServer ES47) and Nautilus (UP1500). I have more systems I
could test but I'd need to get a lot more organized to make space.

In the decade plus I've been around Linux on alpha I've don't actually
recall hearing of anyone using Linux on a Jensen system before :)

Looking around, I'm pretty sure the system I did all my initial work
on was a Jensen.

This is from the linux-.1.1.83 patch:

- * I don't have any good documentation on the EISA hardware interrupt
- * stuff: I don't know the mapping between the interrupt vector and the
- * EISA interrupt number.
- *
- * It *seems* to be 0x8X0 for EISA interrupt X, and 0x9X0 for the
- * local motherboard interrupts..
+ * The vector is 0x8X0 for EISA interrupt X, and 0x9X0 for the local
+ * motherboard interrupts.. This is for the Jensen.

So yup, my initial bringup machine was that DECpc AXP 150, aka "Jensen".

The IO subsystem on that thing was absolutely horrendous. Largely
because of the lack of byte/word accesses, so doing any PCI accesses
had to be encoded on the address bus. Nasty nasty nasty.

The original design with only 32-bit and 64-bit memory accesses really
was horribly horribly wrong, and all the arguments for it were
garbage. Even outside of IO issues, it blew up code size enormously,
but the IO side became truly horrendous.

Oh well. Water under the bridge.

I did have another alpha at some point - going from the original
150HMz EV4 to a 275MHz EV45. I forget what system that was.

Right, I had DEBUG_INFO set. Stupid me. Now it looks much better:

valdese:~/soft/linux/kernel-git> ls -lh arch/alpha/boot/vmlinux*
-rwxr-xr-x 1 ut ut 6.4M Sep 21 18:12 arch/alpha/boot/vmlinux*
-rw-r--r-- 1 ut ut 3.0M Sep 21 18:12 arch/alpha/boot/vmlinux.gz

But it still dies before the first message from the kernel shows up.

I'm sure that other Alpha configurations are still working, but the
Jensen is a bit special. So far I know it's the only Alpha which needs
aboot and not milo as second stage bootloader. aboot itself seems to
be OK, as I can boot the ancient kernel just fine, but when I'm trying
to boot other kernels, I'm coming as far as:

aboot: loading compressed vmlinux-5-15-rc2

and that's it. I don't think I have to do something special with the
compressed image and according to https://tldp.org/HOWTO/SRM-HOWTO/aboot.html
I don't have to. But why do I have the feeling I am doing something
fundamentally wrong? Was there something with a different kernel
jumping in point or a special build option? I remember something like
that, but can't grasp it nor find it on the web.

I would try the SRM bootimage (make bootimage), but the build is broken:

Ok. That's a nasty situation to debug, and it's where things like "git
bisect" are really useful just to narrow things down.

... which isn't an option here. Too bad.

I also assume thete is no virtual environment that looks like a Jensen
that would help debug this. Which all makes it a bit nasty to try to
even guess at what goes wrong.

Yeah, it's more than two decades since I used an alpha, so I'm afraid
I can't help outside of the "let's make it compile again" thing.

It could easily be that the Jensen required that SRM bootimage, but
it's so long ago that I really don't remember at all.

> I would try the SRM bootimage (make bootimage), but the build is broken:

Well, that looks like something that should be fixed, and that I might look at.

This looks like the "make bootimage" thing was never designed to work
in a cross-build environment. I think.

Because it looks like what happens is that when you cross-compile, it
gets the x86-64 'struct exec', and then everything goes sideways.

No, this is lovely. It would be really nice to get that Jensen target
working, if only because of silly historical reasons.

I'll see if I can get around to this.

The attached patch is too ugly for words, and there's no way I will
commit anything like this.

But it at least builds for and seems to successfully make an alpha
bootimage even when cross-compiling on x86-64.

So something to test, perhaps..

Sure, I burned it to a CDROM and booted from that per SRM. The screen
went black for a second, then the SRM console came back with:

?05 HLT INSTR
PC=00000000.20000014 PSL= 00000000.00000007

I wonder if we would be able to see more on a serial line - I can try
that perhaps tomorrow or at the weekend. To find out to what code the
PC is pointing to, I would need to understand to what point in memory SRM
loads the image into.... But this way, the process of loading the kernel
definitely worked - I still don't understand why aboot can load the
old kernel but not the new one. I'll have a look at the aboot sources,
perhaps there's a certain limit on kernel size?

I'm not sure if we can call this progress,
CU,
Uli
