[PATCH v1 0/7] uml: add unspecified HAS_IOMEM dependencies

[PATCH v1 0/7] uml: add unspecified HAS_IOMEM dependencies

[Brendan Higgins]

# TL;DR

This patchset adds a missing HAS_IOMEM dependency to several drivers in
an attempt to get allyesconfig closer to working for ARCH=um.

# What am I trying to do?

This patchset is part of my attempt to get `make ARCH=um allyesconfig`
to produce a config that will build *and* boot to init, so that I can
use it as a mechanism to run tests[1].

This patchset is attempting to deal with

CONFIG_PINCTRL_EQUILIBRIUM=y
CONFIG_MTD_NAND_CADENCE=y
CONFIG_FSI_MASTER_ASPEED=y
CONFIG_CRYPTO_DEV_SAFEXCEL=y
CONFIG_XIL_AXIS_FIFO=y
CONFIG_CRYPTO_DEV_AMLOGIC_GXL=y
CONFIG_XILINX_AXI_EMAC=y

which are selected by `make ARCH=um allyesconfig`, but prevent it from
building.

# How far away are we from an allyesconfig UML kernel?

I have identified 33 Kconfigs that are selected by allyesconfig, but
will either not build on UML, or prevent it from booting. They are:

CONFIG_STATIC_LINK=y
CONFIG_UML_NET_PCAP=y
CONFIG_NET_PTP_CLASSIFY=y
CONFIG_IP_VS=y
CONFIG_BRIDGE_EBT_BROUTE=y
CONFIG_BRIDGE_EBT_T_FILTER=y
CONFIG_BRIDGE_EBT_T_NAT=y
CONFIG_MTD_NAND_CADENCE=y
CONFIG_MTD_NAND_NANDSIM=y
CONFIG_BLK_DEV_NULL_BLK=y
CONFIG_BLK_DEV_RAM=y
CONFIG_SCSI_DEBUG=y
CONFIG_NET_VENDOR_XILINX=y
CONFIG_NULL_TTY=y
CONFIG_PTP_1588_CLOCK=y
CONFIG_PINCTRL_EQUILIBRIUM=y
CONFIG_DMABUF_SELFTESTS=y
CONFIG_COMEDI=y
CONFIG_XIL_AXIS_FIFO=y
CONFIG_EXFAT_FS=y
CONFIG_STM_DUMMY=y
CONFIG_FSI_MASTER_ASPEED=y
CONFIG_JFS_FS=y
CONFIG_UBIFS_FS=y
CONFIG_CRAMFS=y
CONFIG_CRYPTO_DEV_SAFEXCEL=y
CONFIG_CRYPTO_DEV_AMLOGIC_GXL=y
CONFIG_KCOV=y
CONFIG_LKDTM=y
CONFIG_REED_SOLOMON_TEST=y
CONFIG_TEST_RHASHTABLE=y
CONFIG_TEST_MEMINIT=y
CONFIG_NETWORK_PHY_TIMESTAMPING=y

CONFIG_STATIC_LINK=y and CONFIG_UML_NET_PCAP=y already have fixes on
their way.

I also have a patchset that just got accepted to fix
CONFIG_EXFAT_FS=y[2].

So with this patchset and these other three fixes mentioned here, we
will be about a third of the way there. There is only one more broken
config that prevents UML from building, CONFIG_LKDTM=y. After this there
will still be 22 broken configs which will prevent the UML allyesconfig
kernel from reaching the end of init; nevertheless, this is a good
milestone where, once reached, we can stop some of this bleeding by
adding a build test.

# Why won't allyesconfig break again after this series of fixes?

As I mentioned above, I am using UML for testing the kernel, and I am
currently working on getting my tests to run on KernelCI. As part of our
testing procedure for KernelCI, we are planning on building a UML kernel
using allyesconfig and running our tests on it. Thus, we will find out
very quickly once someone breaks allyesconfig again once we get this all
working.

[PATCH v1 1/7] pinctrl: equilibrium: add unspecified HAS_IOMEM dependency

[Brendan Higgins]

Currently CONFIG_PINCTRL_EQUILIBRIUM=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:

ld: drivers/pinctrl/pinctrl-equilibrium.o: in function `eqbr_pinctrl_probe':
drivers/pinctrl/pinctrl-equilibrium.c:908: undefined reference to `devm_platform_ioremap_resource'
ld: drivers/pinctrl/pinctrl-equilibrium.c:223: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the CONFIG_HAS_IOMEM=y dependency.

Nice. I hit this when attempting to force on CONFIG_COMPILE_TEST in
order to build some ARM drivers under UM. Do you have plans to fix
that too?

Do you want to get this in a fix for 5.5?

The only broken configs I found for UML are all listed on the cover
letter of this patch. I think fixing COMPILE_TEST on UM could be
worthwhile. Did you see any brokenness other than what I mentioned on
the cover letter?

Saying you reported a problem and then fixed it kind of does a bit of
disservice to the "reported-by:" tag which we normally use only to
credit the people that do not actually fix the problem.

So in the future, no need for this to be there for patches that you
write yourself.

thanks,

There's a few more in drivers/char/hw_random that you would need.
These were HW_RANDOM_MESON , HW_RANDOM_MTK, HW_RANDOM_EXYNOS,
HW_RANDOM_NPCM, HW_RANDOM_KEYSTONE.

The only one from your series I needed was PINCTRL_EQUILIBRIUM.

I applied this:

That lets me build. However, the code I was attempting to enable
depends on REGMAP, which needs IOMEM too, so I hit that dead end.

Another issue I had was debugging my kunitconfig. This patch helped a bit:

We recently fixed a compile error by adding
depends on OF
and I think OF implies HAS_IOMEM so this should be fixed
now.

Can you confirm?

I'm fairly sure it does not, so both patches are needed.

Patch applied but I augmented it with the recently added
OF dependency so it now says:
depends on OF && HAS_IOMEM

Probably too late now to be helpful, but I can confirm that OF does
NOT depend on HAS_IOMEM, so this patch was still needed.

Thanks regardless!

It looks like my change has not been applied to nand/next; is this the
branch it should be applied to? I have also verified that this patch
isn't in linux-next as of Jan 24th.

Is mtd/linux the correct tree for this? Or do I need to reach out to
someone else?

Cheers

When I sent my Acked-by I supposed someone else would pick the patch,
but there is actually no dependency with all the other patches so I
don't know why I did it... Sorry about that. I'll take it anyway in my
PR for 5.6.

Hey, I know I owe you a reply about debugging your kunitconfig (I'll
try to get to that this week); nevertheless, it looks like this patch
didn't make it into 5.5. Can you make sure it gets into 5.6? It
shouldn't depend on anything else.
