2c3b0baf76 Kernel: Move SpinLock.h into Locking/ 2021-08-07 11:48:00 +02:00

2cd8b21974 Kernel: Add convenience values to the Memory::Region::Access enum 
Instead of `Memory::Region::Access::Read | Memory::Region::AccessWrite`
you can now say `Memory::Region::Access::ReadWrite`.

a1d7ebf85a Kernel: Rename Kernel/VM/ to Kernel/Memory/ 
This directory isn't just about virtual memory, it's about all kinds
of memory management.

6a537ceef1 Kernel: Remove ContiguousVMObject, let AnonymousVMObject do the job 
We don't need an entirely separate VMObject subclass to influence the
location of the physical pages.

Instead, we simply allocate enough physically contiguous memory first,
and then pass it to the AnonymousVMObject constructor that takes a span
of physical pages.

36e36507d5 Everywhere: Prefer using {:#x} over 0x{:x} 
We have a dedicated format specifier which adds the "0x" prefix, so
let's use that instead of adding it manually.

31f30e732a Everywhere: Prefix hexadecimal numbers with 0x 
Depending on the values it might be difficult to figure out whether a
value is decimal or hexadecimal. So let's make this more obvious. Also
this allows copying and pasting those numbers into GNOME calculator and
probably also other apps which auto-detect the base.

b975a74a1d Kernel/USB: Move USB bus information from /proc to /sys 
This patch moves all the USB data from /proc/bus/usb to /sys/bus/usb.

2da0581fd2 Kernel: Replace "folder" => "directory" everywhere 
Folders are a GUI concept. File systems have directories.

d761c5024b AK: Generalize ByteReader 
Also use it instead of CPU.h's possibly_unaligned_data interface

c2792212f4 Kernel: Remove "supervisor" bit from PhysicalPage 
Instead of each PhysicalPage knowing whether it comes from the
supervisor pages or from the user pages, we can just check in both
sets when freeing a page.

It's just a handful of pointer range checks, nothing expensive.

88d490566f Kernel: Rename various *VMObject::create*() => try_create() 
try_*() implies that it can fail (and they all return RefPtr with
nullptr signalling failure.)

c9f6786e8b Kernel: Make various T::class_name() and similar return StringView 
Instead of returning char const*, we can also give you a StringView.

fa9111ac46 Kernel: Rename ProcFSComponentsRegistrar => ProcFSComponentRegistry 
This matches the formatting used in SysFS.

805319ed30 Kernel: Replace "Folder" => "Directory" everywhere 
Folders are a GUI concept, file systems have directories. :^)

5ec3f5433e Kernel: Rename SysFS related classes in PCI code 
Give them names that sound related to SysFS.

60a7a9d523 Kernel: Rename SystemExposedFolder => SysFSDirectory 
"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..."

This matches our common naming style better.

3fae7ca113 Kernel: Clarify and make it easy to not use raw numbers 
Let's put the PCI IDs as enums in the PCI namespace so they're free to
pollute that namespace, but it's also more easier to use them.

3344f91fc4 Kernel/ProcFS: Clean dead processes properly 
Now we use WeakPtrs to break Ref-counting cycle. Also, we call the
prepare_for_deletion method to ensure deleted objects are ready for
deletion. This is necessary to ensure we don't keep dead processes,
which would become zombies.

In addition to that, add some debug prints to aid debug in the future.
