2021-09-12Kernel: Move ACPI and BIOS code into the new Firmware directoryLiav A
This will somwhat help unify them also under the same SysFS directory in the commit. Also, it feels much more like this change reflects the reality that both ACPI and the BIOS are part of the firmware on x86 computers.
2021-09-07Kernel: Make KBuffer::try_create_with_bytes() return KResultOrAndreas Kling
2021-09-07Kernel: Rename FileDescription => OpenFileDescriptionAndreas Kling
Dr. POSIX really calls these "open file description", not just "file description", so let's call them exactly that. :^)
2021-09-07Kernel: Make UserOrKernelBuffer return KResult from read/write/memsetAndreas Kling
This allows us to simplify a whole bunch of call sites with TRY(). :^)
2021-09-06Kernel: Make kernel region allocators return KResultOr<NOP<Region>>Andreas Kling
This expands the reach of error propagation greatly throughout the kernel. Sadly, it also exposes the fact that we're allocating (and doing other fallible things) in constructors all over the place. This patch doesn't attempt to address that of course. That's work for our future selves.
2021-08-29Kernel: Make all ProcFS and SysFS files zero-sizedAndreas Kling
There is no value in exposing particular sizes for these files.
2021-08-29Kernel: Remove unused members in BIOSSysFSDirectoryAndreas Kling
2021-08-22Kernel/SysFS: Don't expose SMBIOS blobs if can't find SMBIOS tablesLiav A
Don't assume that a platform machine will provide at least the 32 bit version of SMBIOS tables. If there's no SMBIOS tables, don't expose directory entries in the /sys/bios/ directory.
2021-08-06Kernel: Move Kernel/Memory/ code into Kernel::Memory namespaceAndreas Kling
2021-08-06Kernel: Rename Kernel/VM/ to Kernel/Memory/Andreas Kling
This directory isn't just about virtual memory, it's about all kinds of memory management.
2021-07-17Kernel: Replace "folder" => "directory" everywhereAndreas Kling
Folders are a GUI concept. File systems have directories.
2021-07-11Kernel: Rename SysFS related classes in BIOS codeAndreas Kling
Give them names that sound related to SysFS.
2021-07-11Kernel: Replace "Folder" => "Directory" everywhereAndreas Kling
Folders are a GUI concept, file systems have directories. :^)
2021-07-11Kernel: Rename SystemExposedFolder => SysFSDirectoryAndreas Kling
"Folder" is a GUI concept, let's call this "Directory". Also, "System" is completely generic, so let's be more specific and call this "SysFS..."
2021-07-11Kernel: Rename SystemExposedComponent => SysFSComponentAndreas Kling
2021-07-11Kernel: Rename SystemRegistrar => SysFSComponentRegistryAndreas Kling
2021-06-29Kernel: Introduce the new SysFSLiav A
The intention is to add dynamic mechanism for notifying the userspace about hotplug events. Currently, the DMI (SMBIOS) blobs and ACPI tables are exposed in the new filesystem.
2021-04-22Everything: Move to SPDX license identifiers in all files.Brian Gianforcaro
SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
2021-03-07Kernel: Fix unaligned read inside map_ebda()Jean-Baptiste Boric
2021-02-14Kernel: Assert if rounding-up-to-page-size would wrap around to 0Andreas Kling
If we try to align a number above 0xfffff000 to the next multiple of the page size (4 KiB), it would wrap around to 0. This is most likely never what we want, so let's assert if that happens.
2020-08-16AK: Rename KB, MB, GB to KiB, MiB, GiBNico Weber
The SI prefixes "k", "M", "G" mean "10^3", "10^6", "10^9". The IEC prefixes "Ki", "Mi", "Gi" mean "2^10", "2^20", "2^30". Let's use the correct name, at least in code. Only changes the name of the constants, no other behavior change.
2020-05-22Kernel: Add convenient ways to map whole BIOS and EBDA into memoryAndreas Kling
This patch adds a MappedROM abstraction to the Kernel VM subsystem. It's basically the read-only byte buffer equivalent of a TypedMapping. We use this in the ACPI and MP table parsers to scan for interesting stuff in low memory instead of doing a bunch of address arithmetic.
