- Change OddObj to X_DISPATCH_HEADER
- Add unknown X_KWAIT_REASON flag
- Fixed InitializeGuestObject mistake
- Replaces unknowns in kthread using nukernel as reference
Previous global TLS bitmap was shared across all processes. Now
per-process TLS bitmaps stored X_KPROCESS structures which should
better match Xbox360 architecture.
When a thread wakes from a kernel wait, the Xenon scheduler boosts its
effective priority by the increment passed to the signaling call
(KeSetEvent, KeReleaseSemaphore, KeReleaseMutant). The boost is clamped
to the per-thread max_dynamic_priority cap, respects the guest
boost_disabled flag, and is drained on the next quantum expiry.
Guest KTHREAD priority fields are now initialized from parent process
defaults, and the previously unknown fields involved have been renamed
to match their identified purpose.
And default ignore_thread_priorities to false.
Map Xenon's 0-31 priority range across all 5 host priority levels
instead of collapsing 0-17 into kNormal.
Use timer-driven quantum decay (~20ms period) matching Xenon's
60-quantum / 3-per-tick cycle to prevent starvation by gradually lowering
effective priority for non-real-time threads (< 18), piggybacking on the
existing 1ms timestamp timer.
Some games persist BGM volume through their own save files but never
call XMPSetVolume. Add a TitlePatch system that intercepts NtReadFile/
NtWriteFile to apply game-specific logic as well as logic to identify
the memory location that the volume data is read into and monitor that
memory location for changes, updating XMP player volume if it changes
during gameplay.
Includes patches for known games with this issue:
Dead or Alive Xtreme 2 (544307D2), PGR4 (4D5307F9) and PGR3 (4D5307D1)
- Added handling (partial or dummy) for SMC actions:
- QUERY_TEMP_SENSOR, QUERY_TRAY, QUERY_AV_PACK, QUERY_SMC_VERSION, QUERY_IR_ADDRESS, QUERY_TILT_SENSOR
- SET_FAN_SPEED_CPU, SET_FAN_SPEED_GPU, SET_DVD_TRAY, SET_IR_ADDRESS, SET_POWER_LED, SET_LEDS
- Stub HalOpenCloseODDTray, XamLoaderGetMediaInfo, XamLoaderGetMediaInfoEx
- Partially Implement HalSendSMCMessage
- Implement XamLoaderGetDvdTrayState
- HalOpenCloseODDTray is used by dash and HalSendSMCMessage can be used by custom dashboards
Externally it is still applied via: ApplyTitleUpdate
But internally it is splitted into:
- FindTitleUpdate
- LoadTitleUpdate
- IsPatchSignatureProper
- ApplyTitleUpdate
Added host window with warning about TU incompatibility
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.
