[PATCH v6 00/11] mtd: add driver for Intel discrete graphics

[PATCH v6 00/11] mtd: add driver for Intel discrete graphics

[Alexander Usyskin]

Add driver for access to Intel discrete graphics card
internal NVM device.
Expose device on auxiliary bus by i915 and Xe drivers and
provide mtd driver to register this device with MTD framework.

This is a rewrite of "drm/i915/spi: spi access for discrete graphics"
and "spi: add driver for Intel discrete graphics"
series with connection to the Xe driver and splitting
the spi driver part to separate module in mtd subsystem.

This series intended to be pushed through drm-xe-next.

V2: Replace dev_* prints with drm_* prints in drm (xe and i915) patches.
    Enable NVM device on Battlemage HW (xe driver patch)
    Fix overwrite register address (xe driver patch)
    Add Rodrigo's r-b

V3: Use devm_pm_runtime_enable to simplify flow.
    Drop print in i915 unload that was accidentally set as error.
    Drop HAS_GSC_NVM macro in line with latest Xe changes.
    Add more Rodrigo's r-b and Miquel's ack.

V4: Add patch that always creates mtd master device
    and adjust mtd-intel-dg power management to use this device.

V5: Fix master device creation to accomodate for devices without
    partitions (create partitoned master in this case)
    Rebase over latest drm-xe-next
    Add ack's
V6: Fix master device release (use rigth idr in release)
    Rebase over latest drm-xe-next
    Grammar and style fixes

[PATCH v6 01/11] mtd: core: always create master device

[Alexander Usyskin]

Create master device without partition when
CONFIG_MTD_PARTITIONED_MASTER flag is unset.

This streamlines device tree and allows to anchor
runtime power management on master device in all cases.

Several of my qemu boot tests fail to boot from mtd devices with this patch
in the mainline kernel. Reverting it fixes the problem. As far as I can
see this affects configurations with CONFIG_MTD_PARTITIONED_MASTER=y when
trying to boot from an mtd partition other than mtdblock0, with the
mtd partition data in devicetree (.../aspeed/openbmc-flash-layout.dtsi).
Is there a guidance describing the changed behavior, by any chance,
and how the boot command line now needs to look like when using one of
the flash partitions as root file system ?

Thanks,
Guenter

I've tried to make is as transparent as possible for the existing users.
Only change is that now every partition has master that is not partitioned.
Is the CONFIG_MTD_PARTITIONED_MASTER=n fixed the problem for you?

No change is expected, can you please describe the devices that you
observe with and without the patch? Maybe there is something wrong in
the core logic.

I am trying to boot supermicro-x11spi-bmc in qemu from flash partition 6.
The qemu command line is something like

     qemu-system-arm -M supermicro-x11spi-bmc,fmc-model=n25q256a13,spi-model=n25q256a13 \
	-kernel arch/arm/boot/zImage -no-reboot -snapshot \
	-audio none \
	-drive file=/tmp/flash,format=raw,if=mtd,index=1 \
	-nic user \
	--append "root=/dev/mtdblock6 rootwait console=ttyS4,115200 earlycon=uart8250,mmio32,0x1e784000,115200n8" \
	-dtb arch/arm/boot/dts/aspeed/aspeed-bmc-supermicro-x11spi.dtb \
	-nographic -monitor null -serial stdio

This is with aspeed_g5_defconfig. Note that the flash models need to be specified.
The default flashes are no longer recognized when booting from qemu since commit
947c86e481a0 ("mtd: spi-nor: macronix: Drop the redundant flash info fields").

The above only works with this patch reverted (or with v6.15 and older, of course).

Alexander, can you please investigate? We need a fix because Guenter
might not be the only affecter user. Otherwise this patch can't stand,
unfortunately.

Maybe something is moved, and it is not /dev/mtdblock6 now.

Guenter, if it works with CONFIG_MTD_PARTITIONED_MASTER=n, can
you dump the list of devices that you can see?

I am trying to boot from "pnor". It looks like the partition data (from devicetree)

Is this with CONFIG_MTD_PARTITIONED_MASTER?

I think that mtd_is_partition is ambiguous now.
We always have master partition when CONFIG_MTD_PARTITIONED_MASTER
is enabled and parent check is useless.
We must check grandparent in this case.
Miquel, am I right?

We can return to older patch version that have created partition
instead of the master device.
Or try to fix mtd_is_partition, like below.
Guenter, is below patch helps?

Looks like all partition parsing is broken when CONFIG_MTD_PARTITIONED_MASTER=y is set.
Alexander, I was able to reproduce with MTDRAM and the mtdparts= kernel parameter.
Build with CONFIG_MTD_MTDRAM=y and CONFIG_MTD_PARTITIONED_MASTER=y,
pass mtdparts=\"mtdram test device:256k(foo)ro,-(bar)\" to the kernel command line.

Before your change:
$ cat /proc/mtd 
dev:    size   erasesize  name
mtd0: 00400000 00020000 "mtdram test device"
mtd1: 00040000 00020000 "foo"
mtd2: 003c0000 00020000 "bar"

After:
$ cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00400000 00020000 "mtdram test device"

Hope this helps!

Thanks,

Richard, I've reproduced your setup (modulo that I must load mtdram manually)
and patch provided in this thread helps to fix the issue.
Can you apply and confirm?

Guenter, as patch not helping and I'm not sure how to reproduce it locally,
can you add drivers/mtd to dynamic debug and collect dmesg for good
and bad cases?
If you have some explanation how to run qemu-system-arm I'll
be glad to try to reproduce it locally.

It doesn't seem to fix the issue if the partition data is in devicetree.

Here is my sample qemu command line:

qemu-system-arm -M supermicro-x11spi-bmc,fmc-model=n25q256a13,spi-model=n25q256a13 \
	-kernel arch/arm/boot/zImage -no-reboot \

	-dtb arch/arm/boot/dts/aspeed/aspeed-bmc-supermicro-x11spi.dtb \
	-nographic -monitor null -serial stdio

This does not create any mtd partitions, even after applying the
patch suggested earlier.

I had a look at the patch again. The whole mtd core makes assumptions on
parenting, which is totally changed with this patch. There are so many
creative ways this can break, I don't believe we are going to continue
this route. I propose to revert the patch entirely for now. We need to
find another approach, I'm sorry.

Alexander, can you please remind me what was your initial problem? I
believe you needed to anchor runtime PM on the master device. Can you
please elaborate again? Why taking the controller as source (the
default, before your change) did not work? Also why was selecting
MTD_PARTITIONED_MASTER not an option for you? I'm trying to get to the
root of this change again, so we can find a solution fixing "the world"
(fast) and in a second time a way to address your problem.

Thanks,

I think reverting is a valid option to consider if the issue turns out to be
a "back to the drawing board" problem.

IIRC the problem is that depending on CONFIG_MTD_PARTITIONED_MASTER
won't fly as PM needs to work with any configuration.
And enforcing CONFIG_MTD_PARTITIONED_MASTER will break existing
setups because mtd id's will change.

On the other hand, how about placing the master device at the end
of the available mtd id space if CONFIG_MTD_PARTITIONED_MASTER=n?
A bit hacky but IMHO worth a thought.

The original problem was that general purpose OS never set
CONFIG_MTD_PARTITIONED_MASTER and we need valid device tree
to power management to work.

We can return to V7 of this patch that only creates dummy master if
CONFIG_MTD_PARTITIONED_MASTER is off.
In this case the hierarchy remains the same.

Miquel, can you re-review v7 and say if it worth to revert current version and
put v7 instead?

After taking inspiration from Richard's wisdom on IRC, we have another
proposal. Let's drop the mtd_master class. We need an mtd device to be
the master device, we already have one but we cannot keep *at the
beginning* of the ID space under the CONFIG_MTD_PARTITIONED_MASTER=n
configuration to avoid breaking userspace. So let's keep the master
anyway, with the following specificities in the problematic case:
- id is allocated from the max value downwards (avoids messing with
  numbering)
- mtd device is simply hidden (same user experience as before)

Apparently this second point, while not natively supported, is something
the block world already does:
https://elixir.bootlin.com/linux/v6.15.1/source/include/linux/blkdev.h#L88

What do you think?

Thanks,

In general, it is fine for me - we have parent mtd initialized and participating
in power management.

I can't see how to bend idr_alloc to allocate from the end and corner case
of full idr range is also will be problematic.

I expected it to work because we can track the highest mtd ID and pass limits
to idr_alloc(), no?

This will produce different ids if there are two mtd chips.
E.g.:
Before patches:
0 - first chip partition 1 - second chip partition
After patches:
0 - first chip partition 1 - first chip master
2 - second chip partition 3 - second chip master

Or we should manually give region for master's ids at the end
of idr range near UINT_MAX.
And that requires careful manual handling of overflows.

Personally, I think it is bad idea to rely on partition number,
but it is the status-quo now.

[PATCH v6 05/11] mtd: intel-dg: register with mtd

[Alexander Usyskin]

Register the on-die nvm device with the mtd subsystem.
Refcount nvm object on _get and _put mtd callbacks.
For erase operation address and size should be 4K aligned.
For write operation address and size has to be 4bytes aligned.

I need to test patch 1, sorry for the delay, I will do that and if I'm
happy with the result I'll apply this patch to mtd/next at -rc1 (better
having this kind of change early in the cycle).

The other patches can go through drm I guess, regardless of the presence
of patch 1. I'll send my acks after testing.

Thanks,
Miquèl

Thanks for testing!
Subsequent patches are depending on patch 1 (at least power management one).
So, I'll sync them with your progress.

I'll push another series revision anyway to add fix for erase flow.
The new patch should be reviewed.
No changes in other patches.
