2025-09-20kern: dma: Add DMA frame allocatorIan Moffett
Introduce a special frame allocation utility to reserve memory for DMA done between devices and the host. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: proc: Keep track of mapped areas with rangesIan Moffett
This commit adds a virtual memory range queue to the process descriptor in order to keep track of mapped pages and free their respective frames upon program exit. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern/amd64: proc: Add proc_self()Ian Moffett
Introduce a new proc_self() function to get the current running process on the current CPU core. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: pci: Implement PCI leaf drivers + AHCI stubIan Moffett
This commit introduces the support for having PCI specific device drivers while providing a tiny AHCI stub that logs the existence of the host bus adapter. The PCI bus itself has a driver for enumerating the devices and associating a specific driver to it, the device drivers themselve must advertise themselves to the PCI driver.

2025-09-19kernel: pci: Add PCI lookup routineIan Moffett
This commit adds a new 'lookup_type_t' for representing the various kinds of lookups one can perform on the PCI bus. The actual code to drive the lookups is exposed as the pci_bus_lookup() routine. When doing a lookup of a PCI device, you must specify the kind of lookup to perform. If a PCI_LU_CLASSREV is requested, only the PCI class and subclass fields in the PCI lookup are used. If the PCI_LU_VENDEV is requested, only the PCI vendor ID and device ID are used in the lookup. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: pci: Add 'class' and 'subclass' to deviceIan Moffett
This commit adds the PCI class and revion (subclass) IDs to the PCI device descriptor provided by L5. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: vfs: Add namei() prototype functionIan Moffett

Use the current platform latch when selecting a syscall window from the current domain. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-17kern/amd64: Implement syscall domains and windowsIan Moffett
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.
