* arm_unicorn: Resolve sign conversion warningsLioncash2019-11-121-1/+1
| | | | | While we're at it, this also resolves a type truncation warning as well, given the code was truncating from a 64-bit value to a 32-bit one.

* | core/arm: Remove obsolete Unicorn memory mappingLioncash2019-07-112-12/+0
|/ | | | | | | | This was initially necessary when AArch64 JIT emulation was in its infancy and all memory-related instructions weren't implemented. Given the JIT now has all of these facilities implemented, we can remove these functions from the CPU interface.
* core/cpu_core_manager: Create threads separately from initialization.Lioncash2019-04-122-17/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our initialization process is a little wonky than one would expect when it comes to code flow. We initialize the CPU last, as opposed to hardware, where the CPU obviously needs to be first, otherwise nothing else would work, and we have code that adds checks to get around this. For example, in the page table setting code, we check to see if the system is turned on before we even notify the CPU instances of a page table switch. This results in dead code (at the moment), because the only time a page table switch will occur is when the system is *not* running, preventing the emulated CPU instances from being notified of a page table switch in a convenient manner (technically the code path could be taken, but we don't emulate the process creation svc handlers yet). This moves the threads creation into its own member function of the core manager and restores a little order (and predictability) to our initialization process. Previously, in the multi-threaded cases, we'd kick off several threads before even the main kernel process was created and ready to execute (gross!). Now the initialization process is like so: Initialization: 1. Timers 2. CPU 3. Kernel 4. Filesystem stuff (kind of gross, but can be amended trivially) 5. Applet stuff (ditto in terms of being kind of gross) 6. Main process (will be moved into the loading step in a following change) 7. Telemetry (this should be initialized last in the future). 8. Services (4 and 5 should ideally be alongside this). 9. GDB (gross. Uses namespace scope state. Needs to be refactored into a class or booted altogether). 10. Renderer 11. GPU (will also have its threads created in a separate step in a following change). Which... isn't *ideal* per-se, however getting rid of the wonky intertwining of CPU state initialization out of this mix gets rid of most of the footguns when it comes to our initialization process.
* kernel/svc: Deglobalize the supervisor call handlersLioncash2019-04-082-15/+12
| | | | | | | | | | | Adjusts the interface of the wrappers to take a system reference, which allows accessing a system instance without using the global accessors. This also allows getting rid of all global accessors within the supervisor call handling code. While this does make the wrappers themselves slightly more noisy, this will be further cleaned up in a follow-up. This eliminates the global system accessors in the current code while preserving the existing interface.
* arm/arm_dynarmic: Remove unnecessary current_page_table memberLioncash2019-04-072-8/+0
| | | | | Given the page table will always be guaranteed to be that of whatever the current process is, we no longer need to keep this around.
* core: Add missing override specifiers where applicableLioncash2019-04-042-3/+2
| | | | | | | | | Applies the override specifier where applicable. In the case of destructors that are defaulted in their definition, they can simply be removed. This also removes the unnecessary inclusions being done in audin_u and audrec_u, given their close proximity.

* core_timing: Convert core timing into a classLioncash2019-02-162-6/+14
| | | | | | | | | | | Gets rid of the largest set of mutable global state within the core. This also paves a way for eliminating usages of GetInstance() on the System class as a follow-up. Note that no behavioral changes have been made, and this simply extracts the functionality into a class. This also has the benefit of making dependencies on the core timing functionality explicit within the relevant interfaces.
* core_timing: Rename CoreTiming namespace to Core::TimingLioncash2019-02-121-3/+3
| | | | | | Places all of the timing-related functionality under the existing Core namespace to keep things consistent, rather than having the timing utilities sitting in its own completely separate namespace.
* arm_dynarmic: Set CNTFRQ valueMerryMage2018-12-181-0/+1
|
* core: Make the exclusive monitor a unique_ptr instead of a shared_ptrLioncash2018-10-152-6/+5
| | | | | | Like the barrier, this is owned entirely by the System and will always outlive the encompassing state, so shared ownership semantics aren't necessary here.
* kernel/thread: Use a regular pointer for the owner/current processLioncash2018-10-101-1/+1
| | | | | | | | | | | There's no real need to use a shared pointer in these cases, and only makes object management more fragile in terms of how easy it would be to introduce cycles. Instead, just do the simple thing of using a regular pointer. Much of this is just a hold-over from citra anyways. It also doesn't make sense from a behavioral point of view for a process' thread to prolong the lifetime of the process itself (the process is supposed to own the thread, not the other way around).
* kernel/thread: Make all instance variables privateLioncash2018-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | Many of the member variables of the thread class aren't even used outside of the class itself, so there's no need to make those variables public. This change follows in the steps of the previous changes that made other kernel types' members private. The main motivation behind this is that the Thread class will likely change in the future as emulation becomes more accurate, and letting random bits of the emulator access data members of the Thread class directly makes it a pain to shuffle around and/or modify internals. Having all data members public like this also makes it difficult to reason about certain bits of behavior without first verifying what parts of the core actually use them. Everything being public also generally follows the tendency for changes to be introduced in completely different translation units that would otherwise be better introduced as an addition to the Thread class' public interface.
* kernel/process: Make data member variables privateLioncash2018-09-301-2/+2
| | | | | | | 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.
* arm_interface: Add missing fpsr/tpidr members to the ThreadContext structLioncash2018-09-301-2/+6
| | | | | | | | | Internally within the kernel, it also includes a member variable for the floating-point status register, and TPIDR, so we should do the same here to match it. While we're at it, also fix up the size of the struct and add a static assertion to ensure it always stays the correct size.

| | | | | | | | | | Given games can also request a 32-bit or 39-bit address space, we shouldn't be hardcoding the address space range as 36-bit.

| * arm_interface: Remove ARM11-isms from the CPU interfaceLioncash2018-09-182-26/+15
| | | | | | | | | | | | | | | | | | This modifies the CPU interface to more accurately match an AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods don't even make sense to keep around for this interface, as Adv Simd is used, rather than the VFP in the primary execution state. This is essentially a modernization change that should have occurred from the get-go.
* | arm_dynarmic: Correct ExclusiveWrite128()'s operationLioncash2018-09-181-2/+2
|/ | | | | | Previously the second half of the value being written would overwrite the first half. Thankfully this wasn't a bug that was being encountered, as the function is currently unused.

* 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.

* arm_dynarmic: Remove IsExecuting check from PrepareRescheduleMerryMage2018-08-131-3/+1

* CPU/Timing: Use an approximated amortized amount of ticks when advancing timing.Subv2018-08-131-1/+10
| | | | | | | | We divide the number of ticks to add by the number of cores (4) to obtain a more or less rough estimate of the actual number of ticks added. This assumes that all 4 cores are doing similar work. Previously we were adding ~4 times the number of ticks, thus making the games think that time was going way too fast. This lets us bypass certain hangs in some games like Breath of the Wild. We should modify our CoreTiming to support multiple cores (both running in a single thread, and in multiple host threads).
