To: linux-arm-kernel
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

* [PATCH] pci: Add and use PCI_GENERIC_SETUP Kconfig entry

We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

This comment seems to suggest PCI_GENERIC_SETUP should be added a few
lines up to preserve the alphabetical sorting.

We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

Cc: Palmer Dabbelt
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

* [PATCH] pci: Add and use PCI_GENERIC_SETUP Kconfig entry
@ 2017-06-23 22:08 ` Palmer Dabbelt
0 siblings, 0 replies; 117+ messages in thread
From: Palmer Dabbelt @ 2017-06-23 22:08 UTC (permalink / raw)
To: linux-arm-kernel
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

Cc: Palmer Dabbelt
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

would be sufficient here - the default is 'n' for all options.

It looks like M68K only includes the PCI Kconfig entry when MMU is enabled. I
moved the select around a bit and it builds the config that was failing for me.
The updated patch is threaded.

We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

Lorenzo Pieralisi's "ARM/ARM64: remove pci_fixup_irqs() usage" series
overlaps with this quite a bit, and includes this patch:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?h=pci/enumeration&id[64036feff4
which makes it so we build setup-irq.o on *all* arches. Can you check
out the pci/enumeration branch and see whether it accomplishes what
you need?

Lorenzo Pieralisi's "ARM/ARM64: remove pci_fixup_irqs() usage" series
overlaps with this quite a bit, and includes this patch:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?h=pci/enumeration&id=5b64036feff4
which makes it so we build setup-irq.o on *all* arches. Can you check
out the pci/enumeration branch and see whether it accomplishes what
you need?

Great, that's even better for me, as I don't have to go touch a bunch of
different arch code :). We'll use that instead when it lands.
Thanks!

Cc: Palmer Dabbelt
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

Cc: Palmer Dabbelt
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.

Cc: Palmer Dabbelt
We wanted to add RISC-V to the list of architectures that used the
generic PCI setup-irq.o inside the Makefile and it was suggested that
instead we define a Kconfig entry and use that.
I've done very minimal testing on this: I just checked to see that
an aarch64 defconfig still build setup-irq.o with the patch applied.
The intention is that this patch doesn't change the behavior of any
build.
