* kernel/codeset: Make CodeSet's memory data member a regular std::vectorLioncash2019-03-221-1/+1
| | | | | | | | | | | The use of a shared_ptr is an implementation detail of the VMManager itself when mapping memory. Because of that, we shouldn't require all users of the CodeSet to have to allocate the shared_ptr ahead of time. It's intended that CodeSet simply pass in the required direct data, and that the memory manager takes care of it from that point on. This means we just do the shared pointer allocation in a single place, when loading modules, as opposed to in each loader.
* kernel: Move CodeSet structure to its own source filesLioncash2019-03-201-0/+1
| | | | | | | | 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.
* kernel/process: Make CodeSet a regular non-inherited objectLioncash2018-10-121-19/+13
| | | | | | | | 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.
* kernel/process: Make data member variables privateLioncash2018-09-301-1/+1
| | | | | | | 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.
* loader: Make the Load() function take a process as a regular reference, not a SharedPtrLioncash2018-09-291-4/+4
| | | | | | | | A process should never require being reference counted in this situation. If the handle to a process is freed before this function is called, it's definitely a bug with our lifetime management, so we can put the requirement in place for the API that the process must be a valid instance.
* memory: Dehardcode the use of fixed memory range constantsLioncash2018-09-251-11/+13
| | | | | | | | The locations of these can actually vary depending on the address space layout, so we shouldn't be using these when determining where to map memory or be using them as offsets for calculations. This keeps all the memory ranges flexible and malleable based off of the virtual memory manager instance state.
* process/vm_manager: Amend API to allow reading parameters from NPDM metadataLioncash2018-09-241-8/+0
| | | | | | | | | 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.

* core/core: Replace includes with forward declarations where applicableLioncash2018-08-311-0/+1
| | | | | | | | | | | The follow-up to e2457418dae19b889b2ad85255bb95d4cd0e4bff, which replaces most of the includes in the core header with forward declarations. This makes it so that if any of the headers the core header was previously including change, then no one will need to rebuild the bulk of the core, due to core.h being quite a prevalent inclusion. This should make turnaround for changes much faster for developers.
* kernel: Eliminate kernel global stateLioncash2018-08-291-2/+5
| | | | | | | | | | | | | | | | | | | | | | 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.
* loader: Remove address mapping remnants from citraLioncash2018-08-151-1/+0
| | | | These mappings are leftovers from citra and don't apply to the Switch.
* loader: Add more descriptive errorsZach Hilman2018-08-101-1/+1
| | | Full list of new errors and descriptions in core/loader/loader.h
* kernel/process: Use accessors instead of class members for referencing segment arrayLioncash2018-08-031-3/+3
| | | | | | | 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.
* core: Make converting constructors explicit where applicableLioncash2018-07-241-1/+1
| | | | | Avoids unwanted implicit conversions. Thankfully, given the large amount of cleanup in past PRs, only this tiny amount is left over to cover.

| * Loaders: Don't automatically set the current process every time we load an application.Subv2017-09-271-8/+7
| | | | | | | | The loaders will now just create a Kernel::Process, construct it and return it to the caller, which is responsible for setting it as the current process and configuring the global page table.
