Undefine 05ec8eddae Kernel: Implement ACPI shutdown 2026-11-07 13:27:30 +01:00
Undefine b2c515561a Kernel: Actually parse the DSDT 2026-11-07 13:27:30 +01:00
Undefine 53b4ea3d31 Kernel: Add make_generic_address_from_io_port 
This will be needed to deduplicate ACPI shutdown code for accessing both
the new generic address field and the legacy x86 port field.
 2026-11-07 13:27:30 +01:00
Undefine f85dbe582f Kernel: Add read_generic_address 
This will be needed to properly implement ACPI shutdown. It's also
missing PCI configuration space support unlike write_generic_address,
because it would require messing with the PCI subsystem and it's not
necessary for now.
 2026-11-07 13:27:30 +01:00
Undefine 373a238d63 Kernel: Clean up access_generic_address into write_generic_address 
Rename the function as it will also get a read counterpart. While at it
clean it up to make it more correct and more readable.
 2026-11-07 13:27:30 +01:00
Undefine d215f42829 Kernel: Move ACPI access_generic_address to a seperate file 
This is not Parser specific code and it makes the file cleaner.
 2026-11-07 13:27:30 +01:00
Undefine 991222fcdb LibACPI: Add structures for PM1ControlRegister and SleepControlRegister 2026-11-07 13:27:30 +01:00
Undefine 41ffa1d87b LibACPI: Add GenericAddressStructure::is_null 2026-11-07 13:27:30 +01:00
Undefine fb809ea9ff Kernel: Remove Parser::can_shutdown 
This was never called.
 2026-11-07 13:27:30 +01:00
Undefine efe9f8d527 Kernel: Remove enable_aml_parsing 
This never did anything.
 2026-11-07 13:27:30 +01:00
Undefine 4808dbe934 Kernel: Print a message about an ACPI reboot only when ACPI is enabled 
When ACPI is disabled we don't try an ACPI reboot so let's not print
a message pretending we do.
 2026-11-07 13:27:30 +01:00
Undefine 5ebe978d8f LibACPI: Make all objects containing a buffer explicitly noncopyable 2026-11-07 13:27:30 +01:00
Undefine d191b2f5d0 Tests: Use release_as in TestAML 
This avoids copies.
 2026-11-07 13:27:30 +01:00
Undefine 2e0c8483fc LibACPI: Explicitly clone a value when evaluating a NameNode 2026-11-07 13:27:30 +01:00
Undefine 452662dd52 LibACPI: Avoid a bunch of copies in the interpreter 2026-11-07 13:27:30 +01:00
Undefine 1895e5e413 LibACPI: Finalize an operand by moving the object into the frame 
This avoids a copy.
 2026-11-07 13:27:30 +01:00
Undefine 7d59d6911d LibACPI: Add a non-const way to get the operand from an OpcodeFrame 
This will be needed to move objects out of the OpcodeFrame.
 2026-11-07 13:27:30 +01:00
Undefine 4285c1b888 LibACPI: Avoid copies when formatting an Object 2026-11-07 13:27:30 +01:00
Undefine e5bb8b4afe LibACPI: Allow initializing an Object by moving a value 2026-11-07 13:27:30 +01:00
Undefine ee1cf23dec LibACPI: Add a failable way to clone an Object 
This will be needed in the kernel.
 2026-11-07 13:27:30 +01:00
Undefine 3db136af6e LibACPI: Make String, Buffer and Package getters const 
Those objects should stay immutable and these getters need to be
accessible from const references.
 2026-11-07 13:27:30 +01:00
Undefine a5e466bc2c LibACPI: Add Object::as_pointer and Object::release_as 
Those will be needed to avoid some copies that are not allowed in the
kernel.
 2026-11-07 13:27:30 +01:00
Undefine b408275768 LibACPI: Ensure reading QWordData compiles correctly 
Later when finish_operand starts taking Object&& the compiler gets
confused and required this to be cast to u64 explicitly.
 2026-11-07 13:27:30 +01:00
Undefine 7d522782c2 AK: Hide non fallible ByteBuffer and StringBuilder APIs in the kernel 
This follows what we already do in structure like the Vector.
 2026-11-06 20:34:06 +01:00
Undefine 9ae1edc095 AK: Improve error propagation in Stream code 2026-11-06 20:34:06 +01:00
Undefine 4160b111f3 AK: Explicitly ensure capacity in Hex and UUID code when in kernel 
The implicit ensure capacity will be unavailable in kernel.
 2026-11-06 20:34:06 +01:00
Undefine 8c2cef2490 AK: Make StringBuilder::trim use trim and not resize 
The ByteBuffer trim function is not fallible but resize is, use trim to
keep this function from returning errors.
 2026-11-06 20:34:06 +01:00
Undefine 6c5c413108 AK: Use more of the fallible StringBuilder APIs in formatting code 
Unfortunately in some places MUST is used because the whole code really
doesn't handle errors at all and uses MUST all over the place.
 2026-11-06 20:34:06 +01:00
Undefine 1a43db2d50 Kernel: Remove two remaining uses of fallible APIs 2026-11-06 20:34:06 +01:00

Undefine 8ab8e7db0f Kernel: Improve error propagation in CommandLine code 2026-11-06 20:34:06 +01:00
Undefine 74ea69459c LibVT: Don't use fallable StringBuilder APIs in code used by the kernel 
While this is quite ugly for now, realistically it points out a real
issue and this change is needed so the kernel compiles after a later
change.
 2026-11-06 20:34:06 +01:00
Undefine 3e01ecd498 LibEDID: Clone a ByteBuffer using clone 
The copy operator will be unavailable in the kernel, so use the clone
function explicitly.
 2026-11-06 20:34:06 +01:00
Undefine 147b06ad2f AK: Add ByteBuffer::clone 
This adds a function to clone a ByteBuffer with a way to propagate
errors if they occur.
 2026-11-06 20:34:06 +01:00
Undefine adede105a1 LibDeviceTree: Switch two calls to try_appendff 
The rest of the calls used the fallible APIs already, but those were
missed.
 2026-11-06 20:34:06 +01:00
Undefine 6c0c3c2f17 Kernel: Use try_append in FATFS SFNUtilities 2026-11-06 20:34:06 +01:00
Undefine d1cb637ec3 Kernel: Propagate errors better in x86_64 ProcessorInfo 
This used some of the non fallible APIs which will be removed from the
kernel.
 2026-11-06 20:34:06 +01:00
Undefine b339c4d6ea LibACPI: Add a missing warnln to dbgln define 
This was missed in TableStream.cpp.
 2026-11-01 15:08:28 +01:00

 2026-11-01 15:08:28 +01:00
UndefineandRatcheT2497 c9e5fa6ada LibACPI: Support reading OpRegionOp and FieldOp 
Those two always come in pairs so lets do it in one commit. This
doesn't yet support evaluating fields as it's not yet needed and would
require setting up callbacks from the interpreter.

Undefine cc1e5ef63b LibACPI: Move object formatting to a dedicated formatter 2026-11-01 15:08:28 +01:00
Undefine 3b0289a11c LibACPI: Make OpcodeFrame start point to right after the opcode 
This makes some math later easier and less error prone since some
opcodes have two bytes.
 2026-11-01 15:08:28 +01:00
Undefine dbfa58bcbe LibACPI: Remove the Node constructor 
It was mistakenly added in the previous PR even though it never has any
other argument than nullptr.
 2026-11-01 15:08:28 +01:00
UndefineandRatcheT2497 c4de12f577 LibACPI: Add missing opcodes to named_object_filter 
The comment noted these should be added, but I accidentally left them
out when refactoring.

 2026-11-01 15:08:28 +01:00
Undefine beb73684de LibACPI: Fix a crash on filtered opcode at root 
When an opcode would get filtered at root it would try to get the
opcode value to print the error message, which is absent on the root
frame.
 2026-11-01 15:08:28 +01:00
Undefine e8b902135b LibACPI: Add a finish_operand variant without an actual operand 
Sometimes reading an operand doesn't produce an operand, but a node or
something else.
 2026-11-01 15:08:28 +01:00
Undefine e508d85725 LibACPI: Add missing AddressSpace enum values 2026-11-01 15:08:28 +01:00

Undefine ea03a27ac6 LibACPI: Allow repeating an operand over a byte count 
Some opcodes encode how many bytes a list of something takes, this
will be needed very soon.
 2026-11-01 15:08:28 +01:00
Undefine b5d4da532a Tests: Add a simple test for the LibACPI AML Interpreter 
The test .aml file was built with iASL 20260930, using
`iasl Tests/LibACPI/test-inputs/scope_and_name.dsl`
 2026-10-28 18:13:04 +01:00
UndefineandRatcheT2497 bc4f17f9f1 Lagom: Build the acpi utility

UndefineandRatcheT2497 d5710bef80 Utilities: Add a simple utility to test out LibACPI 
This is a simple program meant to load a AML table and dump out the
root namespace afterwards.

UndefineandRatcheT2497 95ab8a7e1a LibACPI: Add a skeleton of a AML interpreter 
This a simple skeleton for a non recursive AML parser + interpreter.
For now it support very little stuff, only a couple of opcodes but that
is enough to load a very very simple AML table.

Undefine fe4f387955 Kernel: Clean up ACPI::Parser::locate_main_system_description_table 2026-10-21 19:03:12 +02:00
Undefine 35eaa1c3ab Kernel: Avoid a couple of C-style casts in ACPI code 2026-10-21 19:03:12 +02:00
Undefine ffd990abcb Kernel+LibACPI: Use enums for some fields instead of raw integers 
This makes the code cleaner and allows us to avoid using a bunch of
casts.
 2026-10-21 19:03:12 +02:00
Undefine 1ea6a6af79 Kernel: Move ACPISysFSComponent to a separate file 2026-10-21 19:03:12 +02:00
Undefine efa976647d Kernel: Move ACPISysFSDirectory to a separate file 2026-10-21 19:03:12 +02:00
Undefine f23528bf56 Kernel: Move ACPI find_rsdp from StaticParsing.cpp to Initialize.cpp 
That was the last method in that file and Initialize.cpp was it's only
user.
 2026-10-21 19:03:12 +02:00
Undefine a44aa4baee Kernel: Remove ACPI::StaticParsing find_table code 
After the previous commit this went unused.
 2026-10-21 19:03:12 +02:00
Undefine b854c700be Kernel: Use the ACPI::Parser to find the MADT table in interrupt code 
After the previous commit the full parser is available at this stage.
 2026-10-21 19:03:12 +02:00
Undefine d65ebd86d9 Kernel: Split ACPI init between early and full initilization 
To get rid of the duplicate table parsing code we need the ACPI parser
during interrupt initilization, but to perform the full ACPI
initilization we setup an IRQ handler which needs interrupts to be
initialized. After this split during early initilization we only read
the information about the tables to make it available and do the rest
after interrupts are initilizated. This also keeps ACPI errors as being
not deadly.
 2026-10-21 19:03:12 +02:00
Undefine 8207cfb956 Kernel: Move FADT finding code to Parser 
There's no reason to find the table ahead of time now that we don't
need the interrupt line immedietely. It was also one of the only users
of the StaticParsing find_table code.
 2026-10-21 19:03:12 +02:00
Undefine 3a825ccec0 Kernel: Split out the IRQHandler from ACPI parser and move IRQ lookup 
Splitting it off allows initializing the later than right after Parser
creation, which allows us to move more resposibility to the Parser
instead of mapping the FADT twice.
 2026-10-21 19:03:12 +02:00
Undefine 4ac5026d2c Kernel: Improve error propagation in ACPI code 
This should hopefully get rid of a handful of release_value_but_fixme,
while also making it more likely that we boot on systems where ACPI is
doing something weird (cases we cannot handle yet). While this is
unlikely to occur with our currect range of supported ACPI stuff, when
we add AML interpreting it's quite likely that we will encounter a
cursed DSDT at some point that should not crash the entire system
without a meaningful error.
 2026-10-21 19:03:12 +02:00
Undefine 22115b4545 Kernel: Remove ACPI Parser::get_table_revision 
This method was called only once and could be replaced with a clean
member access a little later.
 2026-10-21 19:03:12 +02:00
Undefine 14b039b24f Kernel+LibACPI: Move table validation code to LibACPI 
It will be used outside of the kernel. While at it clean the function
up a bit to make it a little more readable.
 2026-10-21 19:03:12 +02:00
Undefine 473ef7da92 LibACPI: Move all ACPI definitions to a new library 
Some of those will be required outside of the kernel
 2026-10-21 19:03:12 +02:00
Undefine c45f5c6e2a Kernel: Disable MSI interrupts when IOAPIC is disabled 
MSI interrupts require the IOAPIC to be enabled, trying to run with
`enable_ioapic=off` would cause a kernel panic.
 2026-10-18 14:02:20 +02:00
Undefine 31174c43bf Kernel/FATFS: Implement a hacky replace_child 
This is not a proper implementation, but it's good enough to get
the write support fully working.

Undefine 5e87b78935 LibFileSystem: Ignore ENOTSUP when using chown and chmod during copy 
With FAT write support copying the file would show two errors because
it does not support chown and chmod and would return ENOTSUP. After
this commit these errors are ignored in that case.
 2024-04-21 15:34:33 +02:00
Undefine 2952401c58 Kernel/FATFS: Implement create_child 
This is a large commit because it implements a lot of stuff to make
add_child simpler to get working. This allows us to create new files
on a FAT partition.
 2024-04-21 15:34:33 +02:00
Undefineandimplicitfield 098518cc57 Kernel/FATFS: Implement file modification 
This is the first part of write support, it allows for full file
modification, but no creating or removing files yet.

Undefine fde7bd9190 Kernel/FATFS: Make the debug logs nicer 
They now look the same way as the ones in Ext2FS inodes which are
quite nice for debugging.
 2024-04-21 15:34:33 +02:00
Undefine 33f00a7efb Kernel/FATFS: Cache the cluster list and don't cache the InodeMetadata 
Caching the cluster list allows us to fill the two fields in the
InodeMetadata. While at it, don't cache the metadata as when we
have write support having to keep both InodeMetadata and FATEntry
correct is going to get very annoying.
 2024-04-21 15:34:33 +02:00
Undefine d4badfac72 Kernel/FATFS: Store cluster list instead of block list 
Once we have write support, managing clusters is going to be
