kernel/thread: Minor interface cleanup
2019-04-03 11:46:17 -04:00
Lioncash 28719ee3b4 kernel/svc: Implement svcGetThreadList
Similarly like svcGetProcessList, this retrieves the list of threads
from the current process. In the kernel itself, a process instance
maintains a list of threads, which are used within this function.

Threads are registered to a process' thread list at thread
initialization, and unregistered from the list upon thread destruction
(if said thread has a non-null owning process).

We assert on the debug event case, as we currently don't implement
kernel debug objects.

Lioncash 20cc0b8d3c kernel/wait_object: Make ShouldWait() take thread members by pointer-to-const
Given this is intended as a querying function, it doesn't make sense to
allow the implementer to modify the state of the given thread.

Lioncash 3a846aa80f kernel/process: Report total physical memory used to svcGetInfo
Reports the (mostly) correct size through svcGetInfo now for queries to
total used physical memory. This still doesn't correctly handle memory
allocated via svcMapPhysicalMemory, however, we don't currently handle
that case anyways.

Lioncash 2289e895aa kernel/process: Store the total size of the code memory loaded
This will be necessary to properly report the used memory size in
svcGetInfo.
2019-03-28 22:51:17 -04:00
Lioncash 5d4ab5ec2f kernel/process: Store the main thread stack size to a data member
This will be necessary in order to properly report memory usage within
svcGetInfo.
2019-03-28 18:45:06 -04:00
Lioncash 427f1e3e3d kernel/process: Make Run's stack size parameter a u64
This will make operating with the process-related SVC commands much
nicer in the future (the parameter representing the stack size in
svcStartProcess is a 64-bit value).

Lioncash 7c4bc7b883 kernel/process: Remove unused AddressMapping struct
Another leftover from citra that's now no longer necessary.

Lioncash 1b6bd9d6df kernel: Move CodeSet structure to its own source files
Given this is utilized by the loaders, this allows avoiding inclusion of
the kernel process definitions where avoidable.

This also keeps the loading format for all executable data separate from
the kernel objects.

Lioncash 555cd26ec2 core/hle/kernel: Make Mutex a per-process class.
Makes it an instantiable class like it is in the actual kernel. This
will also allow removing reliance on global accessors in a following
change, now that we can encapsulate a reference to the system instance
in the class.
2019-03-14 20:55:52 -04:00
Lioncash 6eddb60db0 kernel/process: Remove use of global system accessors
Now that we pass in a reference to the system instance, we can utilize
it to eliminate the global accessors in Process-related code.

Lioncash 8e510d5afa kernel: Make the address arbiter instance per-process
Now that we have the address arbiter extracted to its own class, we can
fix an innaccuracy with the kernel. Said inaccuracy being that there
isn't only one address arbiter. Each process instance contains its own
AddressArbiter instance in the actual kernel.

This fixes that and gets rid of another long-standing issue that could
arise when attempting to create more than one process.

Lioncash 1f0c8bfeda core/kernel: Remove unnecessary inclusions
Gets rid of a few unnecessary header dependencies in some source files.

Lioncash 8769604144 kernel/process: Rename GetAllowedProcessorMask() and GetAllowedThreadPriorityMask()
Makes them consistent with their kernel capability counterparts.

kernel/process: Start the main thread using the specified ideal core
2018-12-30 20:32:41 -05:00
Lioncash f80bc712ea kernel: Rename 'default' CPU core to 'ideal' core
This makes the naming more closely match its meaning. It's just a
preferred core, not a required default core. This also makes the usages
of this term consistent across the thread and process implementations.

Lioncash fbeaa330a3 kernel/process: Remove most allocation functions from Process' interface
In all cases that these functions are needed, the VMManager can just be
retrieved and used instead of providing the same functions in Process'
interface.

This also makes it a little nicer dependency-wise, since it gets rid of
cases where the VMManager interface was being used, and then switched
over to using the interface for a Process instance. Instead, it makes
all accesses uniform and uses the VMManager instance for all necessary
tasks.

All the basic memory mapping functions did was forward to the Process'
VMManager instance anyways.

from Citra.

Lioncash 62d4377053 kernel/kernel: Use correct initial PID for userland Process instances
Starts the process ID counter off at 81, which is what the kernel itself
checks against internally when creating processes. It's actually
supposed to panic if the PID is less than 81 for a userland process.
2018-12-18 22:54:01 -05:00
Lioncash 9b3a38e3d3 kernel/process: Make process_id a 64-bit value
In the actual kernel, this is a 64-bit value, so we shouldn't be using a
32-bit type to handle it.
2018-12-18 22:28:55 -05:00
Lioncash 366985ca92 vm_manager: Amend MemoryState enum members
Amends the MemoryState enum to use the same values like the actual
kernel does. Also provides the necessary operators to operate on them.
This will be necessary in the future for implementing
svcSetMemoryAttribute, as memory block state is checked before applying
the attribute.

Lioncash c7462ce712 kernel/process: Make Process a WaitObject
Process instances can be waited upon for state changes. This is also
utilized by svcResetSignal, which will be modified in an upcoming
change. This simply puts all of the WaitObject related machinery in
place.

Lioncash 312690b450 kernel/svc: Implement the resource limit svcGetInfo option
Allows a process to register the resource limit as part of its handle
table.

Lioncash 31d1e06eb1 kernel/process: Move <random> include to the cpp file
<random> isn't necesary directly within the header and can be placed in
the cpp file where its needed. Avoids propagating random generation
utilities via a header file.

Lioncash 6594853eb1 svc: Implement svcGetInfo command 0xF0000002
This retrieves:

if (curr_thread == handle_thread) {
   result = total_thread_ticks + (hardware_tick_count - last_context_switch_ticks);
} else if (curr_thread == handle_thread && sub_id == current_core_index) {
   result = hardware_tick_count - last_context_switch_ticks;
}

Lioncash 90a981a03a kernel/process: Make the handle table per-process
In the kernel, there isn't a singular handle table that everything gets
tossed into or used, rather, each process gets its own handle table that
it uses. This currently isn't an issue for us, since we only execute one
process at the moment, but we may as well get this out of the way so
it's not a headache later on.

Lioncash 1c7a7ed79b svc: Implement svcGetProcessInfo
A fairly basic service function, which only appears to currently support
retrieving the process state. This also alters the ProcessStatus enum to
contain all of the values that a kernel process seems to be able of
reporting with regards to state.

Lioncash 1abed2f4c4 kernel/process: Make CodeSet a regular non-inherited object
These only exist to ferry data into a Process instance and end up going
out of scope quite early. Because of this, we can just make it a plain
struct for holding things and just std::move it into the relevant
function. There's no need to make this inherit from the kernel's Object
type.

Lioncash dccfe193a9 kernel/process: Add a data member to determine if a process is 64-bit or not.
This will be necessary for the implementation of svcGetThreadContext(),
as the kernel checks whether or not the process that owns the thread
that has it context being retrieved is a 64-bit or 32-bit process.

If the process is 32-bit, then the upper 15 general-purpose registers
and upper 16 vector registers are cleared to zero (as AArch32 only has
15 GPRs and 16 128-bit vector registers. not 31 general-purpose
registers and 32 128-bit vector registers like AArch64).

Lioncash cf9d6c6f52 kernel/process: Make data member variables private
Makes the public interface consistent in terms of how accesses are done
on a process object. It also makes it slightly nicer to reason about the
logic of the process class, as we don't want to expose everything to
external code.

Lioncash 75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.

Lioncash acfc801d14 thread/process: Move TLS slot marking/freeing to the process class
Allows making several members of the process class private, it also
avoids going through Core::CurrentProcess() just to retrieve the owning
process.

Lioncash 0cbcd6ec9a kernel: Eliminate kernel global state
As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.

This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.

This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.

The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.

Lioncash 2beda7c2b3 kernel/process: Use accessors instead of class members for referencing segment array
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
