RE: [PATCH] Enable ACPI_ADR_SPACE_PCI_CONFIG in acpi_gbl_default_address_spaces only when ACPI_PCI_CONFIGURED is defined

[Moore, Robert]

Well, I don't like the fact that PCI_CONFIGURED would have to be defined by each current host:

> +#ifdef ACPI_PCI_CONFIGURED

I would rather the logic be reversed:

Thank you for the comments, Erik and Bob!

ACPI_PCI_CONFIGURED is defined in aclinux.h (see below) and used in
several places in evhandler.c and exregion.c.
I'm not sure why we want to introduce ACPI_PCI_NOT_CONFIGURED.  Bob, I
don't understand your concerns
about "have to be defined by each current host".  Can you please shed
some light on it?

Thank you for the comments, Erik and Bob!

ACPI_PCI_CONFIGURED is defined in aclinux.h (see below) and used in several places in evhandler.c and exregion.c.
I'm not sure why we want to introduce ACPI_PCI_NOT_CONFIGURED.  Bob, I don't understand your concerns about "have to be defined by each current host".  Can you please shed some light on it?

It is required in aclinux.h, and thus it is required in every host-dependent configuration file (acfreebsd.h, acmacosx.h, acnetbsd.h, achaiku.h, etc.) I would rather not force these host-specific header files to change.
Bob

Hi Bob,

I don't know the reason for ACPI_PCI_CONFIGURED to be introduced into
aclinux.h. That patch introduced the bug I'm trying to fix: if
CONFIG_PCI is not enabled, the kernel will crash.  Would it be okay to
accept this patch first to fix this kernel crash bug?  We can come up
a plan to fix this host-dependent configuration issue in a separate
patch.  What do you think?

@Erik, I would love to hear your thoughts on this.

Thank you!

RE: [PATCH] Enable ACPI_ADR_SPACE_PCI_CONFIG in acpi_gbl_default_address_spaces only when ACPI_PCI_CONFIGURED is defined

[Moore, Robert]

After giving this some thought, I think we can #define ACPI_PCI_CONFIGURED in the global configuration file (I think it is acconfig.h) - and document why and when it should be removed.

Thank you for the comments, Erik and Bob!

ACPI_PCI_CONFIGURED is defined in aclinux.h (see below) and used in several places in evhandler.c and exregion.c.
I'm not sure why we want to introduce ACPI_PCI_NOT_CONFIGURED.  Bob, I don't understand your concerns about "have to be defined by each current host".  Can you please shed some light on it?

It is required in aclinux.h, and thus it is required in every host-dependent configuration file (acfreebsd.h, acmacosx.h, acnetbsd.h, achaiku.h, etc.) I would rather not force these host-specific header files to change.
Bob


#ifdef CONFIG_PCI
#define ACPI_PCI_CONFIGURED

Hi Bob,

Thank you very much for your new suggestion!  Let me make sure I understand it.

1. We should move the following define from aclinux.h to acconfig.h.

#ifdef CONFIG_PCI
#define ACPI_PCI_CONFIGURED
#endif

2. We should add a comment there to "document why and when it should
be removed".
I don't really know "why and when" since I'm not an expert on ACPI (we
were just trying
to fix a bug :-)).

Thanks!
Weidong
