This patch is outside the scope of what I can accept in arch/sh, and
the subsequent patches in the series seem to depend on it. What would
you like to do for its path upstream?
I've now picked up everything else from this series that I can.

As the dma-mapping maintainer: please pick it. I'd give you an
ACK, but that looks kinda silly if I'm the author as well :)

The code handling non-coherent DMA depends on being able to remap code
as non-cached. But that can't be done without an MMU, so using this
option on NOMMU builds is broken.

This change broke SD card support on J2 because MMC_SPI spuriously
depends on HAS_DMA. It looks like it can be fixed just by removing
that dependency from drivers/mmc/host/Kconfig.

It can't. mmp_spi_probe fails with ENOMEM, probably due to trying to
do some DMA setup thing that's not going to be needed if the
underlying SPI device doesn't support/use DMA.

Adding the linux-mmc and linux-spi lists, as that seems pretty odd.

The mmc_spi driver needs modernizations, so I am not surprised to see
odd things.
My guess is that in ->probe() we check "if
(spi->master->dev.parent->dma_mask)" - > and runs dma_map*()
operations, which fails and leads to bailing out of ->probe() to
return an error code.
However, by looking at the code, one get the feeling that the DMA
support is somewhat prepared to be made optional. I guess it has never
been really tested, as the Kconfig option has "depends on HAS_DMA" -
and it's been like that as long as I can remember.
Kind regards
Uffe

It always worked on our "byte-banged" SPI controller, with no DMA
controller present, before Christoph's changes in this patch series,
and seems to be working now (although I have some other, hopefully
unrelated regressions to debug) with #ifdef CONFIG_HAS_DMA around the
if (spi->master->dev.parent->dma_mask) block in mmc_spi_probe. That's
probably not the right fix though -- why isn't it checking
host->dma_dev instead and only attempting DMA setup if dma_dev is
non-null?

Before that nommu sh builds provided a DMA mapping implementation
that even worked for the streaming side (dma_map_*), but would corrupt
data if you used dma_alloc_coherent memory to communicate with the
device.

I don't think dma_dev can be NULL right now. dma_dev is assigned here:
if (spi->master->dev.parent->dma_mask) {
struct device *dev = spi->master->dev.parent;
host->dma_dev = dev;
but for any OF or real bus device dma_mask never is zero (it actually is
a pointer), and the value of it also is initialized to 32-bit by default,
making this effectively an "if (1) {". The driver needs some way to
communicate if a given device actually is DMA capable or not. Or is that
purely a factor of the platform which would be a little strange.
In which case we should do something like:

I guess "#ifdef CONFIG_HAS_DMA", would work as well as CONFIG_HAS_DMA
can't be "m".
I would also suggest moving the DMA setup things into a separate
function. Then when CONFIG_HAS_DMA is unset, we can use a stub.

Let me cook a patch that we can try.

This switches to using common code for the DMA allocations, including
potential use of the CMA allocator if configured.
Switching to the generic code enables DMA allocations from atomic
context, which is required by the DMA API documentation, and also
adds various other minor features drivers start relying upon. It
also makes sure we have on tested code base for all architectures
that require uncached pte bits for coherent DMA allocations.

Rich already said he is fine with most of the changes but we need to test
the DMA changes first to make sure they didn't break anything.
Thanks again for your continued efforts.

Yes. Sorry I didn't also reply in the original thread.
I'd like to have a way to test the DMA changes or testing feedback
from someone using an affected configuration just because they're
sufficiently nontrivial (Adrian might be able to do this? If so that'd
be great; if not let me know if it's testable in qemu), but the rest
look good to go.
Big thanks for your efforts to clean all this up!

I'll try to build and boot a test kernel on my SH7785LCR tonight or tomorrow (CEST).

Agreed. Much appreciated.

Hello!
I have applied Christoph's full series on top of Linus' tree and I can confirm that
the kernel boots fine on my SH-7785LCR board.
Thus, for the whole series of patches:
Tested-by: John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>
However, independent of Christoph's series, the kernels throws two backtraces during
boot which I think should require a git bisect (unless I missed a configuration option
as I trimmed down the kernel a bit to make sure it's not too big).
See the traces below and let me know what you think.
Adrian

(The second trace is redundant, I actually meant to post the two traces only

I've got a slightly earlier version (my for-next) built for qemu r2d
board, and don't get any such messages. Do you have a lock-debugging
option enabled that's catching a problem, perhaps?

Yes, this patch fixes this particular problem.
There is just a typo in the code which causes a build problem but it's fixed by replacing
"uport" with "port":
CC kernel/module.o
drivers/tty/serial/serial_core.c: In function ‘uart_configure_port’:
drivers/tty/serial/serial_core.c:2385:33: error: ‘uport’ undeclared (first use in this function); did you mean ‘port’?
2385 | uart_any_port_spin_lock_init(uport);

Will test the other changes in a minute.
Can we include the serial fix?

Please be patient. I expect this to be fixed soon through the tty tree.
Note that linux-next already has an alternative fix (f38278e9b810b06a
("serial: sh-sci: Initialize spinlock for uart console")), which is
planned to be reverted once the real fix has been applied.

Indeed, it does. This patch should be picked up as well.
Kernel boots without any errors now.

Hmm, it seems I already have that patch (I'm using Linus' main tree):
commit 002ae7057069538aa3afd500f6f60a429cb948b2
Author: Vlastimil Babka <vbabka@suse.cz>

Okay, kernel 5.0.0 does not suffer from this bug. So I should be able to bisect
this particular issue.
I'm glad I don't have to start bisecting with earlier kernels because these
won't build easily with my current toolchain based on gcc-9.
Will report once I found the bad commit that introduced the problem.

Aha, interesting. The question is whether someone can make use of the crash dump
in this case. I'm surprised it affects init=/bin/systemd but not init=/bin/bash
but maybe the problem with systemd here is a larger memory footprint.

Urgh.. clearly that fell off the table :-(
So yes, that patch works, but as I wrote, I think it's still broken.
Then again, that particular breakage has been there for a long time.
Ooohh.. I have another whole patch-set that fixes that across
architectures which I forgot about too:
https://lkml.kernel.org/r/20191211120713.360281197@infradead.org
that actually included the SH fix.
Then Aneesh got a bunch of those patches merged because he needed it for
Power, but the rest bitrotted again.
Let me rebase/refresh the rest of that and send it out again.

Sounds good. Do you think this new patch set could fix the crash of systemd
that I observed on SH that was introduced with your previous patch?

OK, latest patches here:

Thanks. I just cherry-picked the two patches for SH and applied them on top
of Linus' tree plus the patch 73c348f31b63d28d ("sh: Fix unneeded constructor
in page table allocation") from next-20200710.
The build fails with:

mm/mmu_gather.c: In function ‘tlb_table_invalidate’:

FWIW, I recommend keeping a Debian box at hand where installing the cross-compiler
is a matter of running "apt install gcc-sh4-linux-gnu" ;-).

I happen to have Debian on most of my machines ;-) And I used to
crosstool build my own toolchains for a while, but these days I mostly
just fetch them from kernel.org, since they're being kept up-to-date
fairly often.

I assume it's a problem with your toolchain. I will try to reproduce it tonight
or tomorrow.

For some reason I had a whole bunch of junk left in my checkout and had
to basically: rm `git status -s | awk '{print $2}'`.
Sorry for the noise.
OK, let me go try my own patches :-)

FWIW, I just successfully built the "defconfig" configuration without any problems.
Looking forward for the updated patches, although the patch to fix PGTABLE_LEVELS >2
works for me [1].

This is fixed by [1]:
sh/tlb: Fix PGTABLE_LEVELS > 2
Geert reported that his SH7722-based Migo-R board failed to boot after
commit:
c5b27a889da9 ("sh/tlb: Convert SH to generic mmu_gather")
That commit fell victim to copying the wrong pattern --
__pmd_free_tlb() used to be implemented with pmd_free().
Fixes: c5b27a889da9 ("sh/tlb: Convert SH to generic mmu_gather")

Any chance we get the patches queue up while you're all sorting out
totally independent issues?

I would love to buy only Rich can do that. I'm fine with your patches
and would much appreciate if Rich could queue them up.
I'm also still waiting for my patch to be queued as well.

I read and replied to this from my phone this morning so I was
mistaken about the context in the above reply, but I've now queued
(push still pending after some cleanup of sequence and testing)
everything I can take from this series for linux-next. Some of the
patches seem to depend on work in other maintainers' domains that need
clarification.
