Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-23kern: security: Add initial support for MACIan Moffett
This commit introduces initial support for mandatory access control. As one may recall, L5 follows "everything is memory". In order to interact with a resource, a process must request it from the kernel in the form of a (sometimes) syncable memory buffer. Each resource as well as processes have an access level, if a process attempts to request a resource with a higher access level than it, the request is rejected by the kernel. However, if a process has a greater than or equal access level as a resource, the request can be granted. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-23usr/amd64: Discard .eh_frame and .note sectionsIan Moffett

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-22kern: ahci: Bring up ports via COMRESETIan Moffett
As we rely on resetting the controller via GHC.HR, we'll need to re-establish a link with each implemented port to actually bring them online. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-22kern: ahci: Replace printf calls with dtrace()Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-22kern: ahci: Add initial port bring-up logicIan Moffett
This commit introduces this initial bring-up logic for ports on the HBA. We have allocated the command headers and each FIS RX area for each respective command slot. More work to be done but this lays the groundwork Signed-off-by: Ian Moffett <ian@osmora.org>

2025-09-21kern: vfs: Add support for image-like pathsIan Moffett
Typically filesystems are tree-like, however certain filesystems in the form of images have fixed paths baked into them. This optimizes handling so there isn't a need to unpack it into a rootfs/tmpfs Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: vnode: Add filesystem specific data to vnodeIan Moffett

Abort if the host controller does not support 64-bit addressing Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: ahci: Add initial port startup logicIan Moffett
Here we ensure that the port is in a stopped state, we have also added port descriptor lists to keep track of each port. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: bus: Simply return bus_space, don't remapIan Moffett
As of now, the bootloader handles setting up the MMIO regions and we'll need huge page support (2 megs) for reassigning MMIO space Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: ahci: Ensure HBA is in AHCI-mode after resetIan Moffett
The global host control register (described by section 3.1.2 in the AHCI spec) has an HBA reset bit which resets *everything* to a known state. This means that after the reset, we'll have to indicate to the HBA that we want to speak to it over the AHCI interface. We do it once before the reset if needed, then we do it again after.

2025-09-21kern: ahci: Add AHCI host bus adapter reset implIan Moffett
This commit introduces this initial ahci_init() logic by resetting HBA state on startup. Signed-off-by: Ian Moffett <ian@osmora.org>
