PCI CONF2 access method was deprecated in PCI v2.0 Also, the conf2 ioport range is only activated for use as pci configuration space when conf1 registers are accessed in a particular sequence.
Since the pci-arbiter does not access the conf1 forwarding register, we are safe to remove this completely from gnumach to allow normal I/O use of the conf2 range as modern hardware expects. --- i386/i386/io_perm.c | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) diff --git a/i386/i386/io_perm.c b/i386/i386/io_perm.c index c966102c..6db60f73 100644 --- a/i386/i386/io_perm.c +++ b/i386/i386/io_perm.c @@ -70,12 +70,9 @@ #define PCI_CFG1_START 0xcf8 #define PCI_CFG1_END 0xcff -#define PCI_CFG2_START 0xc000 -#define PCI_CFG2_END 0xcfff #define CONTAINS_PCI_CFG(from, to) \ - ( ( ( from <= PCI_CFG1_END ) && ( to >= PCI_CFG1_START ) ) || \ - ( ( from <= PCI_CFG2_END ) && ( to >= PCI_CFG2_START ) ) ) + ( ( from <= PCI_CFG1_END ) && ( to >= PCI_CFG1_START ) ) /* Our device emulation ops.
