[PATCH 1/3] ata: sata_dwc_460ex: use "dmas" DT property to find dma channel

[PATCH 1/3] ata: sata_dwc_460ex: use "dmas" DT property to find dma channel

[Mans Rullgard]

Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.

This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.

With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

The corresponding patch for the canyonlands devicetree looks something
like this.  I don't have any such hardware or even a manual, so I don't
know what values to use for the various required DT properties of the
DMA controller node, nor can I test it.  The SATA driver works with a
different DMA controller on a Sigma Designs chip.

    If phy_init() fails, do we really need to call phy_exit()?

No, but it doesn't hurt either, and it makes the code slightly simpler.
I can change it though.

Looks good for me (from dw_dmac usage prospective).

You have to move the master assignments and other custom dw_dmac
properties. Maybe at some point I will fix that in dw/platform.c.

Nice!

Btw, last time Linus complained about new warnings. Most of them I have
fixed when moved to external DMA driver. Leftovers IIRC are related to
address space. Are you going to fix them? Otherwise it might be a
headache for him again with strong wording to our address I suppose.

The current sata_dwc driver calls dw_dma_probe() with null pdata which
causes the dw_dma driver to auto-detect most parameters.  It looks like
simply omitting those properties here results in the same thing,
although in this case dw_dma_parse_dt() leaves a devm-allocated pdata
struct adrift.  Deferring the allocation of that and changing the DT
binding doc to make these properties optional for auto-detect-capable
hardware should just work.  Something like this:

There are some issues with __iomem annotations.  Is that the warnings
you refer to?  I'm not getting any regular compiler warnings.

I guess I got them because I'am checking sparse warnings as well.


There is the original Linus' complain.

Yeah, I would like to allow autoconfiguration in case of DT as well and
translate it to use unified device property API.

I have been running my machine mostly configured for pciex1  thus with 
the sata_dwc disabled.
The changes to sata_dwc-460ex do cause an oops.
I will try to give more detailed info over this weekend .

The driver as is upstream would do that since it unconditionally
dereferences a null pointer in the probe function.  My patch fixes that
as a side-effect.

It builds, albeit with an unrelated warning, using the attached config.
Maybe there's a missing config dependency somewhere.

Patch file and .config attached.

Looking into that warning, I doubt it works as is, but that's not caused
by my patch.  I can try to come up with a fix, but again, I can't test it.

Subject: [PATCH] ata: sata_dwc_460ex: use "dmas" DT property to find dma
 channel

Currently this driver only works with a DesignWare DMA engine which it
registers manually using the second "reg" address range and interrupt
number from the DT node.

This patch makes the driver instead use the "dmas" property if present,
otherwise optionally falling back on the old way so existing device
trees can continue to work.

With this change, there is no longer any reason to depend on the 460EX
machine type so drop that from Kconfig.

Shouldn't matter since the compiler flags include -m32, and I only had a
powerpc64 toolchain built.  Anyhow, I built a 32-bit toolchain and it
still builds.

Just to make sure you applied the patch correctly:

mru@unicorn:/tmp/linux-sata$ sha1sum drivers/ata/sata_dwc_460ex.c 
c8a7927840aade75ac62b04a2c9acc8335a34d6f  drivers/ata/sata_dwc_460ex.c

Digging deeper into that warning, it is clearly a bug which has always
been there.  The reason it ever worked appears to be that the 460EX has
a dedicated DMA unit hard-wired to the SATA controller ignoring that
address.  The situation is similar on my hardware.

This clearly means that header file that defines the struct
dw_dma_slave is not included.

After the patch it seems you have to explicitly enable DW_DMAC, so,
either via make nconfig, or by adding
CONFIG_DW_DMAC=y

And yet two lines above there's this:

#include <linux/platform_data/dma-dw.h>

This unconditionally defines struct dw_dma_slave.

Moreover, the line number in the error message above does not match any
version of the file with my patches applied.  I suspect something went
wrong when Julian patched his tree.

The option for enabling the compatibility code selects DW_DMAC.  There
is a missing select DMA_ENGINE, but that won't make any difference here,
and my .config has it enabled anyhow.

Your toolchain has to have addr2line binary. It does a job if you
compile kernel with enough debug information (you may try to use make

Enable CONFIG_DEBUG_INFO, then use this command:

$ addr2line -e vmlinux 0xc043a2c8

Obviously substitute the actual crashing address if it changes.

Enabling debug messages in the sata_dwc driver might also be informative.

memcpy I suppose. Might be copy to unmapped memory.

Anyway, can you enable debug options as I suggested including debug for
sata driver ('dw_dmac_core.dyndbg dw_dmac.dyndbg sata_dwc_460ex.dydbg'
to the cmdline and CONFIG_DYNAMIC_DEBUG=y)?

There's obviously a mismatch somewhere since we know that
sata_dwc_qc_issue isn't in copy_32.S.  Please post the full crash report
you got this address from.

That's strange.  The only way that can happen is if
dmaengine_prep_slave_sg() return NULL, and that really shouldn't be
happening.  Did you turn on debug messages in dw_dma?  You can enable
some extra debug messages by adding "#define VERBOSE_DEBUG" at the top
of drivers/dma/dw/core.c

There are options also for DMA Engine such as CONFIG_DMADEVICES_DEBUG

Could you post the entire kernel log?  There might be important
information before the errors start.

This log is weird.  The sata_dwc_probe() function prints several things
(one using dev_notice()), for instance this:

	/* Read the ID and Version Registers */
	idr = in_le32(&hsdev->sata_dwc_regs->idr);
	versionr = in_le32(&hsdev->sata_dwc_regs->versionr);
	dev_notice(&ofdev->dev, "id %d, controller version %c.%c%c\n",
		   idr, ver[0], ver[1], ver[2]);

The dw_dma_probe() function also prints a line:

	dev_info(chip->dev, "DesignWare DMA Controller, %d channels\n",
		 pdata->nr_channels);

These messages are nowhere to be seen in your log, nor are numerous
others that really must appear before before sata_dwc_qc_prep_by_tag()
can be called.

I'd like to note that the driver works on my Sigma Designs based system
using a different DMA controller, so it's not completely broken.  The
DMA driver could still be faulty, but that still doesn't explain the
missing kernel messages.

I would suggest to use console=tty1 instead of console=tty0.

It would be better to add 'ignore_loglevel' to the cmdline as well.

OK, I've found something.  The dma setup errors are benign, caused by
the driver calling dmaengine_prep_slave_sg() even for non-dma
operations.  The real error is the lock recursion that's reported
later.  I wasn't seeing it since I was running a UP non-preempt kernel.
With lock debugging enabled, I get the same error.  This patch should
fix it.

Subject: [PATCH] ata: sata_dwc_460ex: remove incorrect locking

This lock is already taken in ata_scsi_queuecmd() a few levels up the
call stack so attempting to take it here is an error.  Moreover, it is
pointless in the first place since it only protects a single, atomic
assignment.

OK, I've found something.  The dma setup errors are benign, caused by
the driver calling dmaengine_prep_slave_sg() even for non-dma
operations.  The real error is the lock recursion that's reported
later.  I wasn't seeing it since I was running a UP non-preempt kernel.
With lock debugging enabled, I get the same error.  This patch should
fix it.

This lock is already taken in ata_scsi_queuecmd() a few levels up the
call stack so attempting to take it here is an error.  Moreover, it is
pointless in the first place since it only protects a single, atomic
assignment.

This will create a second empty line, though I don't care it is so minor.

The patch leaves one blank line before the following block comment.  I
think it looks better that way.

It might be faster if you just edit (remove 3 lines) directly in the file.

Sorry, didn't realise it conflicted with an intervening patch I had in

Subject: [PATCH] ata: sata_dwc_460ex: remove incorrect locking

This lock is already taken in ata_scsi_queuecmd() a few levels up the
call stack so attempting to take it here is an error.  Moreover, it is
pointless in the first place since it only protects a single, atomic
assignment.

Now we're getting somewhere.  The dma transfer is set up and initiated,
but then nothing happens.  Comparing the old sata_dwc driver, from
before the switch to dmaengine, with the dw_dma driver, I noticed an
obvious problem: the descriptors are filled in using the wrong byte
order.  This patch might fix that.

Subject: [PATCH] dmaengine: dw: fix byte order of hw descriptor fields

If the DMA controller uses a different byte order than the host CPU,
the hardware linked list descriptor fields need to be byte-swapped.

This patch makes the driver write these fields using the same byte
order it uses for mmio accesses to the DMA engine.  I do not know
if this is guaranteed to always be correct.

Now we're getting somewhere.  The dma transfer is set up and initiated,
but then nothing happens.  Comparing the old sata_dwc driver, from
before the switch to dmaengine, with the dw_dma driver, I noticed an
obvious problem: the descriptors are filled in using the wrong byte
order.  This patch might fix that.

Subject: [PATCH] dmaengine: dw: fix byte order of hw descriptor fields

If the DMA controller uses a different byte order than the host CPU,
the hardware linked list descriptor fields need to be byte-swapped.

This patch makes the driver write these fields using the same byte
order it uses for mmio accesses to the DMA engine.  I do not know
if this is guaranteed to always be correct.

No, it means the IO is little endian, and the DMA reads from memory in
little endian while the host CPU is big endian.

Unless I made a mistake, there should be no difference there.  Still got

Well, that didn't help.  I still think it's part of the problem, but
something else must be wrong as well.  The various Master Select fields
look like a good place to start.  Also, the manual says the LLP_SRC_EN
and LLP_DST_EN flags should be cleared on the last in a chain of blocks.
The old sata_dwc driver does this whereas dw_dma does not.

It might be worthwhile to try reverting drivers/ata/sata_dwc_460ex.c to
v4.0 (leaving the rest at 4.4-rc5) just to make sure that's a good
reference.  I've verified that this builds.

Master number (which is here would be either 1 or 0) should not affect
as long as they are connected to the same AHB bus (I would be
surprised if they are not).

Easy to fix, however I can't get how it might affect.

It would be nice.

I noticed thanks to DWC_PARAMS that burst size is hardcoded to 32
items on this board, however registers for SATA program it to 64. I
remember that I got no interrupt when I programmed transfer width
wrongly (64 bits against 32 bits) when I ported dw_dmac to be used on
Intel SoCs.

One more thing, I have a patch to monitor DMA IO, we may check what
exactly the values are written / read  in DMA. I can share it
tomorrow.

P.S. I also noticed that original driver enables interrupt per each
block and sets protection control bits.

I think they are not.  The relevant part of the block diagram for the
460EX looks something like this:

I think they are not.  The relevant part of the block diagram for the
460EX looks something like this:

      +-----+
      | CPU |

         |

    |

 +------+

The DMA-SATA link is private and ignores the address, which is the only
reason the driver can possibly work (it's programming a CPU virtual
address there).

From the Atmel doc:

  In Table 17-1 on page 185, all other combinations of LLPx.LOC = 0,
  CTLx.LLP_S_EN, CFGx.RELOAD_SR, CTLx.LLP_D_EN, and CFGx.RELOAD_DS are
  illegal, and causes indeterminate or erroneous behavior.

Most likely nothing happens, but I think it ought to be fixed.  In fact,
I have a patch already.

Come to think of it, I have an AVR32 dev somewhere.  Maybe I should dust
it off.

If you look at the original code the SMS and DMS are programmed
statically independent on DMA direction, so LLP is programmed always
to master 1. I don't think your scheme is reflecting this right. I
could imagine two AHB buses, one of them connects CPU, SATA and RAM,
and the other CPU and DMA.

In any case on all Intel SoCs and AVR32, and as far as I can tell on
Spear13xx (Viresh?) there is not a case, that's why I hardly imagine
that the problem is in master numbers by themselves.

Check the code again.  The original code swaps SMS and DMS depending on
direction, and it sets LMS to 1.  Put differently, it always sets the
memory side 1 and the device side to 0.  The dw_dma driver sets SMS and
DMS to the src/dst_master values provided through dma_request_channel()
regardless of the current direction and LMS always zero.  If those
values didn't matter, why would the fields exist in the first place?

The 460EX is a PowerPC system.  Expect unusual topologies.

I have an AT32ATK1006.  Can you suggest a good test to exercise the DMA

Check the code again.  The original code swaps SMS and DMS depending on
direction, and it sets LMS to 1.  Put differently, it always sets the
memory side 1 and the device side to 0.  The dw_dma driver sets SMS and
DMS to the src/dst_master values provided through dma_request_channel()
regardless of the current direction and LMS always zero.  If those
values didn't matter, why would the fields exist in the first place?

The 460EX is a PowerPC system.  Expect unusual topologies.

I have an AT32ATK1006.  Can you suggest a good test to exercise the DMA
engine?

Yeah, that won't work since there are numerous changes afterward.  Just
revert the entire file back to 4.0 like this:

debugging enabled.

Subject: [PATCH] ata: sata_dwc_460ex: remove incorrect locking

This lock is already taken in ata_scsi_queuecmd() a few levels up the
call stack so attempting to take it here is an error.  Moreover, it is
pointless in the first place since it only protects a single, atomic
assignment.

Oh, that one again.  My patch still applies.  Here it is as applied to
that revision of the file.

I guess it's a time to submit this one to upstream with proper Fixes:
tag (which I suppose the initial commit of the driver).

As promised the patch I have to debug IO of DW DMA. Didn't check though
if it applies cleanly on top of recent vanilla kernel.

I used to have a patch to implement this in dw_dmac driver. However, I
dropped it at some point. Seems we need it back and now I possible
have a good explanation why.

Because someone can have more than one AHB bus on the system and
connect DMA to all of them (up to 4).

Yes, we have to clear those bits. I will do a patch or you already have one?

So, the original driver (with patch from Måns) works, right?

Are you still able to find that patch?  Shouldn't be too hard to do from
scratch if not.

Which apparently these guys did.  Well, not a full-blown AHB bus, but
they seem to be using two master interfaces.

BTW, there's a good reason for wiring it like this.  If the source and
destination are on different buses, the DMA engine can do a read and a
write in each cycle.  Otherwise the reads and writes have to be issued
alternately.

Looks that way to me.  At least it's able to read the partition table.
What happens after that is hard to tell, but I don't see any obvious
errors.

Looks that way to me.  At least it's able to read the partition table.
What happens after that is hard to tell, but I don't see any obvious
errors.

Okay, let's summarize what we have:

0. AR: Get a working reference for PPC 460EX SATA driver
1. AR: Clear LLP_EN bits at the last block of LLP transfer
2. AR: Rename masters to 'memory' and 'peripheral' and change them per
DMA direction
3. AR: Set LMS (LLP master) to 'memory' when do LLP transfers
4. CHECK: PROTCTL bit (documentation says that recommended value is
0x01)
5. CHECK: Other bits in CFG register (FIFO_MODE, FCMODE)
6. CHECK: Block interrupts vs. one interrupt at the end of block chain
(Måns, I missed how any of them is ignored)
7. AR: Test everything on Intel SoCs such as Baytrail, CherryTrail, etc
(SPI, UART, dmatest), AVR32 (MMC, dmatest), PPC 460EX (Onboard SATA)


I can share my working branch with a set of patches regarding to
dw_dmac. We may do our work based on that code and after I'll submit
everything to upstream. Does it sound okay for you, guys?

To different buses? Intel HW uses two masters and they are quite equal

Okay. We need first to have a confirmation. I would try to set other

Good idea.  I'd call them memory and device though to match existing

Presumably that's decided by the bus.

The interrupt handler looks at the StatusTfr and StatusErr registers and
ignores StatusBlock.

I can test on AVR32.  That is as far as I know the only system I have
with this DMA engine.

If you can influence anyone of the radeon guys to have a look at the

I will  be happy to help test in that area as well .

Judging by the block diagram in the 460EX datasheet [1], and by the fact
that the old SATA driver works despite using an invalid address, the DMA
FIFO of the controller isn't connected to the AHB bus at all but
directly to master 0 on the DW DMA controller.  Master 1 of the DMA
controller is connected to the AHB bus, which is bridged to the main
system bus.

I haven't managed to find a full manual for the 460EX.

Judging by the block diagram in the 460EX datasheet [1], and by the fact
that the old SATA driver works despite using an invalid address, the DMA
FIFO of the controller isn't connected to the AHB bus at all but
directly to master 0 on the DW DMA controller.  Master 1 of the DMA
controller is connected to the AHB bus, which is bridged to the main
system bus.

I haven't managed to find a full manual for the 460EX.

Indeed, thanks, Julian!

I might ask you to test my branch with set of patches when it will be
ready (apparently after Xmas) if you are okay with that.

Måns, also I would ask you to test on your hardware (AVR32) as well if
you have no objections.

Nope, documentation says that it is direct representation of hprot[3:1]
wires on the master interface. Also it refers to AMBA spec, so, if you
have access to AMBA spec I think we might get it from there.

I have to refresh my memory, since BLOCK interrupts should be enabled
(unmasked) separately. I have forgotten which type of interrupt is
generated in this case, BLOCK, or XFER after each block, or only one
XFER at the last block (LLP.LOC = 0) and BLOCK are ignored. So, will
check later.

If you have Intel Haswell, BayTrail, Braswell, CherryTrail, Broadwell,
you have it as well as long you have LPSS block there. (Most of them
are Atoms).

That's assuming AMCC didn't change something.

I interpreted the, admittedly a bit vague, documentation as meaning
BLOCK interrupts are signalled after each block and XFER interrupts
after the last block.

I've picked out the relevant changes from your branch and made some
additional improvements.  A few notes:

- The __be32/__le32 typedefs for the DMA descriptor fields are necessary

I've picked out the relevant changes from your branch and made some
additional improvements.  A few notes:

- The __be32/__le32 typedefs for the DMA descriptor fields are necessary
  to avoid a million sparse warnings (and sparse is correct to warn).
- Using #ifdef CONFIG_AVR32 is a step back, IMO, since this driver may
  well be used on another big endian system some day.  The Kconfig logic
  for selecting this option could perhaps be improved though.

Tested on AVR32 (DMA driver) and Sigma SMP8642 (SATA driver).

Hmm… Which version of sparse are you using? I always run builds with
sparse enabled and didn't see anything.

Maybe runtime chosen accessors will be better than ifdefs?
I don't like the Kconfig option which limits application of the
(compiled) driver.

You need to enable endian checking with CF=-D__CHECK_ENDIAN__

Are there any systems that could otherwise run the same kernel that use
this hardware with different byte order?  I doubt it.

It's no more limited than a hard #ifdef AVR32 in the driver code.

I will look soon for sure.

One comment still regarding to lli types. We can avoid warnings by

You mean if we access the lli->field directly? I didn't quite get what

Yes, accessing any of those fields directly with my patch gives a sparse
warning.  It's situations like these those checks are intended for.

Otherwise it makes that struct looks ugly.

What's so ugly about it?  IMO data should be declared as the type it
actually is, and here we have fields that might have a different byte
order from the host CPU.  The __be32 and __le32 types were invented to
make such situations clear and allow automatic (sparse) checking.  I'd
say the price of one small typedef is well worth it.  The actual code is
not impacted since it must use the accessor macros anyhow.

Okay, let's move with current state.

I have few style minors and a question.

So, in type definitions can we use __dw32 instead of dw_u32?
In DWC_DEFAULT_CTLLO() can we do tab indentation for \ ?

Now the question: who do you prefer to submit the series (dw_dmac)? Me
or you?

In case you would like to do it (what I see in your dwc-sata branch
today):

Sure, no problem.

Sure, no problem.

Is there a wrong indentation somewhere?  I don't see it.

I'll fix the above, give your changes a review, and add my sign-off
before sending the series, today or during the weekend.

Means in your case the ' \' is used, in mine — '\t\' at the end of
lines.

OK.

Just to be sure we are on the same page. I assume your dwc-sata branch
as for submitting.

Oh, I see it now.  Two lines have a space rather than a tab since a tab
would push them over 80 columns.  Now those lines could be shortened by
simply dropping the "_is_slave" since this is necessarily true if the
other half of the && is.

Yes, I'm not aware of anything that needs to change in that branch.

Yes, direction is precisely from the _is_slave space.
