Add a timeout so that if data never arrives, the system doesn't get
locked up.

This commit introduces scancoding buffering as well as an I/O tap so
that it may be exposed outside of the driver

This implementation walks through the entire table of registered
interrupt handlers and calls each driver handler.
The driver is to return a value of 1 if the interrupt is theirs and has
been handled, otherwise it is to return 0. The handling core is to
respoond to a 1 by exiting the table walk early, and responds to a 0 by
continuing.

Ensure no uninitialized garbage ends up in the handler structure after
we've allocated it.

This commit makes the interrupt table global so it can be accessed
through assembly.

This commit reserves the first 64 vectors for the I/O APIC input lines.
During an IRQ, each handler will be called to see which one handles it.

This commit introduces the interrupt registration framework for L5 and
accounts for I/O APIC IRQ inputs, and interrupt priority levels encoded
within bits 7:4 of the interrupt vector

Introduce a helper function to convert legacy ISA IRQ numbers to the GSI
numbers assigned to an I/O APIC pin

To ensure that all residual data does not remain for the mapping in its
table, we write a flat zero if prot is also zero i.e., no permissions

These sometimes cause issues so we are better off just stripping them

As of now, the bootloader handles setting up the MMIO regions and we'll

This commit handles base address registers by storing them in a bar
array within the PCI device structure. We also introduced a helper

their underlying region

Use the current platform latch when selecting a syscall window from the
current domain.
Signed-off-by: Ian Moffett <ian@osmora.org>
|
|
A syscall domain in the L5 kernel is a fixed list of "syscall windows",
each syscall window represents a specific platform and/or syscall model.
A platform latch within each domain determines which window / platform
should be visible. Since syscall domains are per-process, these changes
are local to their respective processes.
