[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [RFC PATCH 00/35] Move all PCIBIOS* definitions into arch/x86
This goal of these series is to move the definition of *all* PCIBIOS* from
include/linux/pci.h to arch/x86 and limit their use within there.
All other tree specific definition will be left for intact. Maybe they can
be renamed.
PCIBIOS* is an x86 concept as defined by the PCI spec. The returned error
codes of PCIBIOS* are positive values and this introduces some complexities
which other archs need not incur.
PLAN:
1. [PATCH v0 1-36] Replace all PCIBIOS_SUCCESSFUL with 0
2a. Audit all functions returning PCIBIOS_* error values directly or
indirectly and prevent possible bug coming in (2b)
2b. Make all functions returning PCIBIOS_* error values call
pcibios_err_to_errno(). *This will change their behaviour, for good.*
3. Clone a pcibios_err_to_errno() into arch/x86/pci/pcbios.c as _v2.
This handles the positive error codes directly and will not use any
PCIBIOS* definitions. So calls to it have no outside dependence.
4. Make all x86 codes that needs to convert to -E* values call the
cloned version - pcibios_err_to_errno_v2()
5. Assign PCIBIOS_* errors values directly to generic -E* errors
6. Refactor pcibios_err_to_errno() and mark it deprecated
7. Replace all calls to pcibios_err_to_errno() with the proper -E* value
or 0.
8. Remove all PCIBIOS* definitions in include/linux/pci.h and
pcibios_err_to_errno() too.
9. Redefine all PCIBIOS* definitions with original values inside
arch/x86/pci/pcbios.c
10. Redefine pcibios_err_to_errno() inside arch/x86/pci/pcbios.c
11. Replace pcibios_err_to_errno_v2() calls with pcibios_err_to_errno()
12. Remove pcibios_err_to_errno_v2()
