Bananymous 84b3289a2a Kernel: Move Scheduler::yield() lock check after interrupts disabled 
I have no idea why this solves a bug where current processor has
scheduler lock at the beginning of yield.

fine :D

Bananymous b23511edb1 LibC: Don't use BAN inside pwd.cpp 
This made pwd.cpp require libstdc++ which meant that getlogin() also
needed libstdc++. This made build process of libstdc++ require itself
which is of course not possible.

Bananymous 53e572f072 Kernel: Fix s_fast_page_lock type on 32 bit target 2024-05-29 18:04:23 +03:00
Bananymous c2b6ba0d5a Userspace: Start work on GUI and WindowServer 
Current implementation can create custom windows and each window has
its own framebuffer. When window wants to write its framebuffer to the
screen it will send a message to the WindowServer using unix sockets.
 2024-05-29 16:00:54 +03:00
Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects 
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.

Bananymous 99270e96a9 Kernel: Lock debug lock while printing fault details 
This allows multiprocessor to dump clean output on concurrent faults

Bananymous 87d52e5ebe Kernel: Fix timer early wake message 
When printing early return message, current time was read twice. This
could lead to early return check failing, but when printing and reading
the time again subtraction overflow would happen.

Bananymous f5987b68ff BAN: Mark some class methods as constexpr 2024-05-28 01:07:29 +03:00
Bananymous a1ab44d39f Kernel: Optimize disk reads to read multiple sectors at once 
Old StorageDevice::read_sectors() read each sector separately if the
underlying disk had a disk cache. This patch allows multiple sectors to
be read even if the disk cache exists and contains some of the sectors.

Only sectors that could not be found from the disk cache are actually
read from the disk. This optimization is not done for writing, which
still will write each sector separately, if disk cache has no memory to
store new sectors. It would feel kind of unnecessary optimization as you
have greater problems if disk cache cannot allocate a single page.

Bananymous 8b1514e575 Kernel: Make all storage devices readable and writable 
I only had a {read,write}_impl defined for ATABaseDevice. This patch
moves that implmentation to general storage device.
 2024-05-27 13:41:55 +03:00
Bananymous 2d3810874d Kernel: Fix thread signal handling 
Threads will now only handle signals once they are not holding any
mutexes. This removes some dead locks.
 2024-05-26 20:08:35 +03:00
Bananymous a4c634e4bf Sysroot: Fix us keymap bracket keys 2024-05-26 16:08:29 +03:00
Bananymous 2a4d986da5 Kernel: Add preliminary support for PCIe 
Only segment 0 is supported, but devices can now be accessed through
mmio.

Adding more segments would require adding argument to every PCI API so
it is left for later.
 2024-05-25 20:50:07 +03:00
Bananymous 3b18730af6 BuildSystem: Don't build libstdc++ as libc is not complete enough 2024-05-25 19:17:13 +03:00
Bananymous df260fe0e8 Kernel: Process::validate_pointer_access now maps the whole range 
This fixes a bug where userspace provided address is not fully mapped
and the kernel tries to read/write it while using PageTable fast page.

In the future userspace input should be copied on syscall entry, so
userspace could not modify the input during syscall. Currently there
is change that userspace input passes kernel syscall validation and
after that userspace could modify the input before the value is
actually used.
 2024-05-24 14:14:17 +03:00
Bananymous 2be4fe8404 Kernel: Make PageTable::s_fast_page_lock non-recursive 
This lock is only used in wrapper of PageTable. There is no possiblity
of taking the lock outside of these wrappers.
 2024-05-24 14:12:35 +03:00

Bananymous 0af74fccda Kernel/LibC: Rework dirent structure 
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.

Bananymous e77de1804f Kernel: Fix some race conditions in TCP stack 
Remove race condition if two acks are to be sent one after another.

Always unblock semaphore once TCP thread has done something. This
allows better chance of TCP sending to succeed.

There are multiple places in the networking code that would require
thread-safe entering to blocking mode. I should add some API for this
so that a lot of race conditions could be removed.
 2024-05-21 01:53:45 +03:00
Bananymous e00b92225d Kernel: Fix E1000 interrupt handling condition 
I had written the ICR register check backwards which lead to interrupt
handling only when it was not needed, and no handling when it was
needed. This somehow still worked, just much slower often requiring tcp
resends from the server.

Bananymous ee8fca9439 General: Update discord badge 2024-05-20 21:07:15 +03:00
Bananymous adc562feb8 General: Add simple contribution guide lines 
README now contains simple contribution guide lines that should be
followed. I am now more open for public contributions to the repo
if people are interested.

Create a discord server and link it to the README. Discord seems to be
a nice platform for general messaging.
 2024-05-20 20:44:34 +03:00
Bananymous af8fa4014f BuildSystem: Always download cmake instead of using host's 
If cmake was installed from snap, build system would cause an error
because some libfakeroot GLIBC requirement.

Bananymous 7480e71801 BuildSystem: Download binutils and gcc as tar balls 
I am not sure why I changed this earlier. This is much cleaner and
faster as git doesn't have to recieve all patches and resolve deltas

Bananymous f1b2d7530d Kernel: Rework AML namespace and object hierarchy 
Remove tree-like structure from AML. This allows more spec compliant
parsing of named objects inside not yet declared devices.

This also allows AML to be run thread safely. All object adds/removes
are now guarded by a mutex.

Bananymous b89bafa165 Kernel: Add support for power button shutdown 
This patch implements basic support for power button using ACPI
fixed events. I still need to implement general purpose events
and embedded controller for full power button support.
 2024-04-15 23:55:25 +03:00
Bananymous 9fac5f94ba Kernel: Fix entering ACPI mode 
My condition to check wheter to enter ACPI mode was incorrect.
I only entered ACPI mode if I already was in ACPI mode :DD
 2024-04-15 15:05:48 +03:00
Bananymous 5affc73ee6 Kernel: Parse ACPI namespace only after TTY is initialized 
This allows better debugging when there is no serial port available.
 2024-04-12 16:47:17 +03:00
Bananymous 027016ddae Kernel: Load all SSDTs and PSDTs 
Spec says to load all tables with unique OEM table IDs but that seem
wrong.

 2024-04-12 01:47:40 +03:00
Bananymous 93ddee5956 Kernel: Implement locking for AML 
Now global lock uses the actual global lock. Currenly if no lock
can be acquired, we just panic the kernel so that I remember to
implement it properly once AML is running concurrently.
 2024-04-11 01:48:46 +03:00
Bananymous 0184e5beb5 Kernel: AML tries to initialize processors when entering ACPI mode 
I had forgotten that Processors used to be a different definition
in AML.

I also implemented reads/writes for FieldElement/IndexFieldElement
that fit in 64 bits. Reads and writes to buffer are still a TODO.
 2024-04-11 01:48:46 +03:00
Bananymous 3f2e110eab Kernel: Entering ACPI mode now actually enables ACPI 
I used to only initialize devices, but now I send ACPI_ENABLE if
