Add a simple IDEDiskDevice class that implements DiskDevice from VFS.

KERNEL_OBJS = \
Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work.

init.o \
kmalloc.o \
StdLib.o \
Kernel: Move i386.{cpp,h} => Arch/i386/CPU.{cpp,h} There's a ton of work that would need to be done before we could spin up on another architecture, but let's at least try to separate things out a bit.
2019-06-07 18:02:01 +00:00
Arch/i386/CPU.o \
Process now maps regions immediately when they are allocated. This avoids having to do a separate MM.mapRegionsForTask() pass. Also, more Task => Process renaming that I apparently hadn't saved yet.
2018-11-01 12:15:46 +00:00
Process.o \
Kernel: Introduce threads, and refactor everything in support of it. The scheduler now operates on threads, rather than on processes. Each process has a main thread, and can have any number of additional threads. The process exits when the main thread exits. This patch doesn't actually spawn any additional threads, it merely does all the plumbing needed to make it possible. :^)

Import the "gerbert" kernel I worked on earlier this year. It's a lot crappier than I remembered it. It's gonna need a lot of work.

Syscall.o \
Kernel: Move devices into Kernel/Devices/.
2019-04-03 10:36:40 +00:00
Devices/IDEDiskDevice.o \
Kernel: Move VM-related files into Kernel/VM/. Also break MemoryManager.{cpp,h} into one file per class.
2019-04-03 13:13:07 +00:00
VM/MemoryManager.o \
VM/Region.o \
VM/VMObject.o \
VM/PageDirectory.o \
VM/PhysicalPage.o \
Kernel: Refactor MemoryManager to use a Bitmap rather than a Vector This significantly reduces the pressure on the kernel heap when allocating a lot of pages. Previously at about 250MB allocated, the free page list would outgrow the kernel's heap. Given that there is no longer a page list, this does not happen. The next barrier will be the kernel memory used by the page records for in-use memory. This kicks in at about 1GB.
2019-06-11 11:13:02 +00:00
VM/PhysicalRegion.o \
Kernel: Implement a simple virtual address range allocator. This replaces the previous virtual address allocator which was basically just "m_next_address += size;" With this in place, virtual addresses can get reused, which cuts down on the number of page tables created. When we implement ASLR some day, we'll probably have to do page table deallocation, but for now page tables are only deallocated once the process dies.
2019-05-17 01:40:15 +00:00
VM/RangeAllocator.o \
Add IRQHandler class that can be subclasses to handle an IRQ. Also move Keyboard to a class implementation using this pattern.
2018-10-22 10:58:29 +00:00
Console.o \
Move kprintf to its own file. It has nothing to do with VGA anymore.
2018-10-22 11:20:35 +00:00
IRQHandler.o \
Start adding a basic /proc filesystem and a "ps" utility.
2018-10-23 09:57:38 +00:00
kprintf.o \
Start working on virtual consoles/TTYs. This is a mess right now, but I'd rather commit as I go.
2018-10-30 12:59:29 +00:00
RTC.o \
Kernel: Move TTY-related files into Kernel/TTY/.

FileSystem/FIFO.o \
Move ELFLoader code into Kernel/.
2018-12-02 19:27:08 +00:00
Scheduler.o \
Move DoubleBuffer to its own files.
2018-12-03 00:51:44 +00:00
DoubleBuffer.o \
Switch into 1024x768x32bpp VESA LFB mode at boot. This is going to be pretty cool once I can hook up the Widgets/ code to it.
2019-01-09 01:29:11 +00:00
KSyms.o \
Kernel: Add KParams class for accessing kernel cmdline parameters (#188)
2019-06-04 10:54:27 +00:00
KParams.o \
Kernel: More work towards POSIX SHM, also add ftruncate().
2019-04-08 23:10:00 +00:00
SharedMemory.o \
Kernel: Move FS-related files into Kernel/FileSystem/
2019-04-03 10:25:24 +00:00
FileSystem/DevPtsFS.o \
Kernel: Move devices into Kernel/Devices/.
2019-04-03 10:36:40 +00:00
Devices/BXVGADevice.o \
Kernel: Much improved BochsVGA (BXVGA) support. Instead of cowboy-calling the VESA BIOS in the bootloader, find the emulator VGA adapter by scanning the PCI bus. Then set up the desired video mode by sending device commands.
2019-02-06 09:17:26 +00:00
PCI.o \
Kernel: Move devices into Kernel/Devices/.
2019-04-03 10:36:40 +00:00
Devices/PS2MouseDevice.o \
Kernel: Implement serial port driver This implements a basic 8250 UART serial port driver. It does not currently handle (or enable) interrupts, nor any runtime configuration.
2019-06-08 13:24:34 +00:00
Devices/SerialDevice.o \
Kernel: Move FIFO into FileSystem/ and Socket+LocalSocket into Net/.
2019-04-06 18:29:48 +00:00
Net/Socket.o \
Net/LocalSocket.o \
Kernel: Move networking related files into Kernel/Net/.
2019-04-02 17:54:38 +00:00
Net/IPv4Socket.o \
Net/TCPSocket.o \
Net/UDPSocket.o \
Net/NetworkAdapter.o \
Net/E1000NetworkAdapter.o \
Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1. Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address). This is just hard-coded logic right now but can be expanded to support a proper routing table. Also start moving kernel networking code into Kernel/Net/.
2019-04-02 13:46:44 +00:00
Net/LoopbackAdapter.o \
Net/Routing.o \
Kernel: Add a systrace() syscall and implement /bin/strace using it. Calling systrace(pid) gives you a file descriptor with a stream of the syscalls made by a peer process. The process must be owned by the same UID who calls systrace(). :^)
2019-04-22 16:44:45 +00:00
Net/NetworkTask.o \
Kernel: Make ProcessTracer inherit from File.
2019-04-28 13:02:55 +00:00
ProcessTracer.o \
Kernel: Add a beep() syscall that beeps the PC speaker. Hook this up in Terminal so that the '\a' character generates a beep. Finally emit an '\a' character in the shell line editing code when backspacing at the start of the line.
2019-05-15 19:40:41 +00:00
Devices/PCSpeaker.o \
Kernel: Add InodeFile, a File subclass for regular files. Finally everything that can be held by a FileDescriptor actually inherits from the File class.
2019-05-30 11:39:17 +00:00
FileSystem/InodeFile.o \
FileSystem: Add a Custody class that represents a parent/child guardianship. A custody is kind of a directory entry abstraction that represents a single entry in a parent directory that tells us the name of a child inode. The idea here is for path resolution to produce a chain of custody objects.
2019-05-30 15:46:08 +00:00
FileSystem/Custody.o \
Kernel: Make ProcessTracer inherit from File.
2019-04-28 13:02:55 +00:00
File.o
Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 12:17:43 +00:00
VFS_OBJS = \
Kernel: Move FS-related files into Kernel/FileSystem/

Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9. This is then used to implement the userspace dbgprintf() in a far more efficient way than what we had before. :^)
2019-04-18 14:08:52 +00:00
Devices/DebugLogDevice.o \
Kernel: Rename OffsetDiskDevice to DiskPartition
2019-06-02 09:38:37 +00:00
Devices/DiskPartition.o \
Kernel: Implement MBR partition loader (#168) This implements a basic MBR partition loader, which removes the reliance on a hard-coded filesystem offset in the stage2 init.
2019-06-02 12:57:44 +00:00
Devices/MBRPartitionTable.o \
Kernel: Move FS-related files into Kernel/FileSystem/
2019-04-03 10:25:24 +00:00
FileSystem/FileSystem.o \
FileSystem/DiskBackedFileSystem.o \
FileSystem/Ext2FileSystem.o \
FileSystem/VirtualFileSystem.o \
Kernel: Rename FileDescriptor to FileDescription. After reading a bunch of POSIX specs, I've learned that a file descriptor is the number that refers to a file description, not the description itself. So this patch renames FileDescriptor to FileDescription, and Process now has FileDescription* file_description(int fd).
2019-06-07 07:36:51 +00:00
FileSystem/FileDescription.o \
Kernel: Move FS-related files into Kernel/FileSystem/
2019-04-03 10:25:24 +00:00
FileSystem/SyntheticFileSystem.o
Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 12:17:43 +00:00
Integrate ext2 from VFS into Kernel.
2018-10-17 08:55:43 +00:00
AK_OBJS = \
../AK/String.o \
Add a VFS::absolutePath(InodeIdentifier). This is pretty inefficient for ext2fs. We walk the entire block group containing the inode, searching through every directory for an entry referencing this inode. It might be a good idea to cache this information somehow. I'm not sure how often we'll be searching for it. Obviously there are multiple caching layers missing in the file system.
2018-10-28 11:20:25 +00:00
../AK/StringImpl.o \
Finally hook up the mkdir code to a syscall. Added a /bin/mkdir that makes directories. How very neat :^) There are various limitations because of missing functionality.
2018-11-18 13:57:41 +00:00
../AK/StringBuilder.o \
AK: Try to use StringViews more for substrings and splitting.
2019-04-16 00:39:16 +00:00
../AK/StringView.o \
Add a fast memcpy() using MMX when we're moving >= 1KB. This is a nice speedup for WindowServer. I'll eventually have to do this with SSE but the kernel doesn't support SSE yet so this is it for now.
2019-02-07 07:46:52 +00:00
../AK/FileSystemPath.o \
Kernel/AK: Move ELF loader to AK This is in preparation for eventually using it in userspace. LinearAddress.h has not been moved for the time being (as it seems to be only used by a very small part of the code).
2019-05-23 14:42:13 +00:00
../AK/StdLibExtras.o \
Kernel: Change the format of /proc/all to JSON. Update ProcessManager, top and WSCPUMonitor to handle the new format. Since the kernel is not allowed to use floating-point math, we now compile the JSON classes in AK without JsonValue::Type::Double support. To accomodate large unsigned ints, I added a JsonValue::Type::UnsignedInt.
2019-06-29 07:04:45 +00:00
../AK/JsonObject.o \
../AK/JsonValue.o \
../AK/JsonArray.o \

../AK/ELF/ELFImage.o \
../AK/ELF/ELFLoader.o
Integrate ext2 from VFS into Kernel.
2018-10-17 08:55:43 +00:00
Kernel: Use a multiboot header instead of a convoluted two-part bootloader. The old bootloader was hilariously complicated, requiring a floppy disk with the kernel on it, and a hard drive with the file system. This patch removes the floppy disk from the equation and replaces it with a multiboot header. This means the kernel can now be booted with qemu-system-i386 -kernel kernel

CXXFLAGS += -ffreestanding -mregparm=3 -mno-80387 -mno-mmx -mno-sse -mno-sse2
AK: Add Vector(std::initializer_list<T>) constructor. This allows us to construct a Vector from an initializer list like so: Vector<Object> objects = { object1, object2, object3 };
