add typed guest pointer template
add X_KSPINLOCK, rework spinlock functions.
rework irql related code, use irql on pcr instead of on XThread
add guest linked list helper functions
renamed ProcessInfoBlock to X_KPROCESS
assigned names to many kernel structure fields
… over to referencing state through ppc_context as much as possible, it'll make implementing things like kernel processes much easier in the future
Move forward definitions of kernel types into kernel_fwd.h
Stub implementation of XamLoaderGetMediaInfoEx
Partially implement XamSetDashContext
implement XamGetDashContext
Stub implementation of XamUserIsUnsafeProgrammingAllowed
Stub implementation of XamUserGetSubscriptionType
Expanded the supported object types for ObReferenceObjectByHandle and wrapped the logic for encoding the type in a constexpr function
ObReferenceObjectByName was taking lpstring_t for first param, but the function actually takes X_ANSI_STRING ptr
NtReleaseMutant actually does not return anything from KeReleaseMutant, it just checks the handle and returns whether it was invalid.
Changed the raise/lower irql functions to just set the irql on the pcr instead of setting it on field of Processor, processor is a shared object and irql is per-thread
Semi-stub implementation of KeGetImagePageTableEntry. I locked at it in the HV and got it so the values are in the same range the HV returns + actually reflect the page & memory range, but i doubt its equal to the values the hv returns on real hw. Used by modern dashboards, don't know for what.
Log error message for ObDereferenceObject w/ null ptr.
Allocate a special fixed page that dashboards reference, currently don't know what the data on that page is supposed to be.
Add current_irql field to X_KPCR
Added Device object member of XObject::Type enum
Added some notes about other gpu registers, found a table of register names and indices in xam
Fully defined the structure.
Single copy of it + single timer across all modules, managing it is now the responsibility of KernelState.
add global_critical_region::PrepareToAcquire, which uses Prefetchw on the global crit. We now know we can use Prefetchw on all cpus that have AVX.
add KeQueryInterruptTime, which is used by some dashboards.
add threading::NanoSleep
- Changed name of config option to apply_title_update to better reflect what that option does
- Mount TU package to UPDATE: partition
- Simplified UserModule::title_id()
- Splitted loading module into two parts to allow applying TUs and custom patches
C++17ification!
- Filesystem interaction now uses std::filesystem::path.
- Usage of const char*, std::string have been changed to
std::string_view where appropriate.
- Usage of printf-style functions changed to use fmt.
Previously XexUnloadImage did not cleanup the image fully,
and if XexLoadImage was to be called again on the same module,
it was not initialized fully, leading to a crash when using it.
This changes almost all locks held by guest threads to use a single global
critical region. This emulates the behavior on the PPC of disabling
interrupts (by calls like KeRaiseIrqlToDpcLevel or masking interrupts),
and prevents deadlocks from occuring when threads are suspended or
otherwise blocked.
This has performance implications and a pass is needed to ensure the
locking is as granular as possible. It could also break everything
because it's fundamentally unsound. We'll see.
