[pci] Use linker tables for runtime selectable PCI APIs

2025-11-24T20:54:01+00:00

Use the linker table mechanism to enumerate the underlying PCI I/O APIs, to allow PCIAPI_CLOUD to become architecture-independent code. Signed-off-by: Michael Brown

[pci] Allow PCI configuration space access mechanism to vary by range

2025-11-24T19:10:49+00:00

On some systems (observed on an AWS EC2 c7a.medium instance in eu-west-2), there is no single PCI configuration space access mechanism that covers all PCI devices. For example: the ECAM may provide access only to bus 01 and above, with type 1 accesses required to access bus 00. Allow the choice of PCI configuration space access mechanism to be made on a per-range basis, rather than being made just once in an initialisation function. Signed-off-by: Michael Brown

[init] Show initialisation function names in debug messages

[pxe] Use a weak symbol for isapnp_read_port

2025-06-24T12:34:41+00:00

Use a weak symbol for isapnp_read_port used in pxe_preboot.c, rather than relying on a common symbol. Signed-off-by: Michael Brown

[uart] Allow for dynamically registered 16550 UARTs

2025-06-21T22:34:32+00:00

Use the generic UART driver-private data pointer, rather than embedding the generic UART within the 16550 UART structure. Signed-off-by: Michael Brown

[uart] Allow for the existence of non-16550 UARTs

2025-06-20T11:52:04+00:00

Remove the assumption that all platforms use a fixed number of 16550 UARTs identifiable by a simple numeric index. Create an abstraction allowing for dynamic instantiation and registration of any number of arbitrary UART models. The common case of the serial console on x86 uses a single fixed UART specified at compile time. Avoid unnecessarily dragging in the dynamic instantiation code in this use case by allowing COMCONSOLE to refer to a single static UART object representing the relevant port. When selecting a UART by command-line argument (as used in the "gdbstub serial " command), allow the UART to be specified as either a numeric index (to retain backwards compatiblity) or a case-insensitive port name such as "COM2".

[memmap] Rename addr/last fields to min/max for clarity

2025-05-23T15:55:42+00:00

Use the terminology "min" and "max" for addresses covered by a memory region descriptor, since this is sufficiently intuitive to generally not require further explanation. Signed-off-by: Michael Brown

[uheap] Expose external heap region directly

2025-05-22T15:28:15+00:00

We currently rely on implicit detection of the external heap region. The INT 15 memory map mangler relies on examining the corresponding in-use memory region, and the initrd reshuffler relies on performing a separate detection of the largest free memory block after startup has completed. Replace these with explicit public symbols to describe the external heap region. Signed-off-by: Michael Brown

[bios] Use generic external heap based on the system memory map
