36 hourskernel: net: Implement IEEE 802.3 + ARP requestsIan Moffett
Introduce IEEE 802.3 related headers such as ones containing the structure of an ethernet frame as well as its types. This commit additionally introduces ARP request logic. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskernel: ahci: Don't zero allocated PAs anymoreIan Moffett
This is no longer needed as the Hyra PMM now does this automatically by default. Signed-off-by: Ian Moffett <ian@osmora.org>
4 dayskernel: Prevent physmem clobbers + zero memoryIan Moffett
To prevent a situation where there is a data race between one thread freeing physical memory and one allocating physical memory. Do not immediately reuse freed physical memory. Instead, keep allocating upwards and once there is no more room, wrap the last_idx back to the bitmap free index. We now also zero allocated physical memory for security reasons.

- Only check PxSCTL.SET within the port reset logic - Do not create device file for ATAPI devices (yet) Signed-off-by: Ian Moffett <ian@osmora.org>

- Set PxCMD.SUD if the HBA supports staggered spin-up to ensure the device will be detectable. - Wait for the device link to be established - Detect and log SATA link speed Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel/amd64: bus: Make MMIO_OFFSET same as HDDMIan Moffett
Drivers may be invoked even while other processes are start up and therefore their MMIO mappings must be shared. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>

8 dayskernel: physmem: Only set bits if memory is foundIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: proc: Make per-process flags volatileIan Moffett
The per process flags field is a frequently modified/read field and MUST NOT give stale data. Be very sure that the compiler does not optimize away accesses. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: sched: No yield on wait + intoff on yieldIan Moffett
Temporary workaround for issue relating to hangs on process yield with a sleeping parent Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: cons: Add ANSI cursor pos reset sequenceIan Moffett
- Add support for the "\033[H" ANSI escape sequence to reset the cursor to the 'home' position Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel: cons: Invert console cursor colorIan Moffett

8 dayskernel: spawn: Ensure pathbuf is zeroedIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskernel/amd64: Add `alloc` to pmap_update_tbl()Ian Moffett
Add an `alloc' paramater to pmap_update_tbl() to ensure that functions like pmap_map() and pmap_unmap() have control over, whether or not to allocate new page table entries. This is useful as unmapping memory does not require new page table entries to be allocated and doing so anyways may result in undefined behaviour such as hangs.
