5 dayskernel: ahci: Fix issue of undetectable devicesIan Moffett
- 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>
5 dayskernel: ahci: Improve port reset logicIan Moffett
- 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>
5 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>
5 dayskernel: cons: Make ANSI_BLUE a darker shadeIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskernel/amd64: Flush TLB per cache attr updateIan Moffett
- Use pmap_update_tbl() to ensure that the TLB is flushed when caching attributes are updated. Signed-off-by: Ian Moffett <ian@osmora.org>

6 daysusr: libc: Add stat() in sys/stat.hIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 dayskernel: physmem: Only set bits if memory is foundIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 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>
6 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>
6 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>
6 dayskernel: cons: Invert console cursor colorIan Moffett

6 dayskernel: spawn: Ensure pathbuf is zeroedIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
6 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.
