Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 15:17:43 +03:00
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.
2018-10-16 12:01:38 +03:00
_start.o \
init.o \
kmalloc.o \
StdLib.o \
i386.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 15:15:46 +03:00
Process.o \
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.
2018-10-16 12:01:38 +03:00
i8253.o \
Kernel: Rename Keyboard to KeyboardDevice.
2019-02-17 10:39:09 +03:00
KeyboardDevice.o \
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.
2018-10-16 12:01:38 +03:00
CMOS.o \
PIC.o \
Syscall.o \
Add basic paging. Only identity maps the bottom 4MB as a start.
2018-10-18 00:13:55 +03:00
IDEDiskDevice.o \
Add a Console device and start refactoring screen output.
2018-10-21 22:59:43 +03:00
MemoryManager.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 13:58:29 +03:00
Console.o \
Move kprintf to its own file. It has nothing to do with VGA anymore.
2018-10-22 14:20:35 +03:00
IRQHandler.o \
Start adding a basic /proc filesystem and a "ps" utility.
2018-10-23 12:57:38 +03:00
kprintf.o \
Kernel: Rewrite ProcFS. Now the filesystem is generated on-the-fly instead of manually adding and removing inodes as processes spawn and die. The code is convoluted and bloated as I wrote it while sleepless. However, it's still vastly better than the old ProcFS, so I'm committing it. I also added /proc/PID/fd/N symlinks for each of a process's open fd's.
2019-02-03 14:33:11 +03:00
ProcFS.o \
Start working on virtual consoles/TTYs. This is a mess right now, but I'd rather commit as I go.
2018-10-30 15:59:29 +03:00
RTC.o \
TTY.o \
Add a PTY multiplexer (/dev/ptmx) device. When you open /dev/ptmx, you get a file descriptor pointing to one of the available MasterPTY's. If none are available, you get an EBUSY. This makes it possible to open multiple (up to 4) Terminals. :^) To support this, I also added a CharacterDevice::open() that gets control when VFS is opening a CharacterDevice. This is useful when we want to return a custom FileDescriptor like we do here.
2019-01-16 15:36:10 +03:00
PTYMultiplexer.o \
Add basic PTY support. For now, there are four hard-coded PTYs: /dev/pt{m,s}[0123] Use this in the Terminal to open a pty pair and spawn a shell.
2019-01-15 08:30:19 +03:00
MasterPTY.o \
SlavePTY.o \
Move the scheduler code to its own class. This is very mechanical.
2018-11-08 00:15:02 +03:00
VirtualConsole.o \
Add primitive FIFO and hook it up to sys$pipe(). It's now possible to do this in bash: cat kernel.map | fgrep List This is very cool! :^)
2018-11-12 03:28:46 +03:00
FIFO.o \
Move ELFLoader code into Kernel/.
2018-12-02 22:27:08 +03:00
Scheduler.o \
Move DoubleBuffer to its own files.
2018-12-03 03:51:44 +03:00
DoubleBuffer.o \
Move ELFLoader code into Kernel/.
2018-12-02 22:27:08 +03:00
ELFImage.o \
Move kernel symbolication code out of init.cpp and into its own KSym files. Also use a simple array of { dword, const char* } for the KSyms and put the whole shebang in kmalloc_eternal() memory. This was a fugly source of kmalloc perma-frag.
2018-12-25 00:59:10 +03:00
ELFLoader.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 04:29:11 +03:00
KSyms.o \
Add a /dev/pts filesystem and make PTY allocation dynamic. You can now open as many PTY pairs as you like. Well, it's actually capped at 8 for now, but it's just a constant and trivial to change. Unregistering a PTY pair is untested because I didn't want to start mucking with that in Terminal right now.
2019-01-30 02:49:20 +03:00
DevPtsFS.o \
Kernel: Rename BochsVGADevice to BXVGADevice.
2019-02-17 10:40:30 +03:00
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 12:17:26 +03:00
PCI.o \
Add a simple PS/2 mouse device. It's not hooked up to anything just yet, but it does read movement deltas.
2019-01-11 04:28:53 +03:00
PS2MouseDevice.o \
Kernel: Begin implementing UNIX domain sockets.
2019-02-14 16:17:38 +03:00
Socket.o \
Kernel: Start adding support for E1000 network adapters.
2019-03-10 17:25:33 +03:00
LocalSocket.o \
Kernel+LibC+Userland: Start working on an IPv4 socket backend. The first userland networking program will be "ping" :^)
2019-03-12 17:51:42 +03:00
IPv4Socket.o \
Kernel: Factor out TCP parts of IPv4Socket into a TCPSocket class.
2019-03-14 14:20:38 +03:00
TCPSocket.o \
IPv4: Factor out UDP parts of IPv4Socket into a UDPSocket class.
2019-03-14 14:43:18 +03:00
UDPSocket.o \
Kernel: Start adding support for E1000 network adapters.
2019-03-10 17:25:33 +03:00
NetworkAdapter.o \
Kernel: Add a NetworkTask and a received network packet queue. It will be easier to deal with incoming packets in a separate task.
2019-03-11 14:43:45 +03:00
E1000NetworkAdapter.o \
NetworkTask.o
Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 15:17:43 +03:00
VFS_OBJS = \
Move VFS sources into Kernel/.
2019-01-23 07:13:17 +03:00
DiskDevice.o \
Kernel: Add Device base class for CharacterDevice. ..to prepare for adding a BlockDevice class.
2019-02-16 02:47:20 +03:00
Device.o \
Move VFS sources into Kernel/.
2019-01-23 07:13:17 +03:00
CharacterDevice.o \
Kernel: Add empty BlockDevice class.
2019-02-16 02:52:58 +03:00

FileSystem.o \
DiskBackedFileSystem.o \
Ext2FileSystem.o \

FileDescriptor.o \
SyntheticFileSystem.o
Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 15:17:43 +03:00
Integrate ext2 from VFS into Kernel.
2018-10-17 11:55:43 +03:00
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 14:20:25 +03:00
../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 16:57:41 +03:00
../AK/StringBuilder.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 10:46:52 +03:00
../AK/FileSystemPath.o \
../AK/StdLibExtras.o
Integrate ext2 from VFS into Kernel.
2018-10-17 11:55:43 +03:00
Move WindowServer to userspace. This is a monster patch that required changing a whole bunch of things. There are performance and stability issues all over the place, but it works. Pretty cool, I have to admit :^)
2019-02-17 02:13:47 +03:00

INCLUDE_FLAGS = -I.. -I.
AK: Add Retained<T>, like RetainPtr, but never null. Also use some Clang attribute wizardry to get a warning for use-after-move.
2019-02-25 14:43:52 +03:00
CLANG_FLAGS = -Wconsumed -m32 -ffreestanding -march=i686
Make kernel build with clang. It's a bit faster than g++ and seems to generate perfectly fine code. The kernel is also roughly 10% smaller(!)
2018-11-09 14:20:44 +03:00
#SUGGEST_FLAGS = -Wsuggest-final-types -Wsuggest-final-methods -Wsuggest-override #-Wsuggest-attribute=noreturn
Add a simple IDEDiskDevice class that implements DiskDevice from VFS.
2018-10-16 15:17:43 +03:00
Canonicalize the path used by sh. With a bunch of LibC work to support the feature. LibC now initializes AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^)

Add a very hackish /proc/PID/stack. It walks the stack and identifies anything that looks like a kernel symbol. This could be a lot more sophisticated.

Make it run in QEMU. Looks like the problem was the weirdly-sized floppy image file. I guess QEMU was inferring the floppy disk geometry from the image size.
