* kernel/process: Start the main thread using the specified ideal coreLioncash2018-12-281-2/+2
| | | | | This matches kernel behavior in that processes are started using their specified ideal core, rather than always starting on core 0.
* kernel: Rename 'default' CPU core to 'ideal' coreLioncash2018-12-284-21/+21
| | | | | | 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.
* kernel/thread: Move process thread initialization into process.cppLioncash2018-12-283-36/+30
| | | | | | | | | | This function isn't a general purpose function that should be exposed to everything, given it's specific to initializing the main thread for a Process instance. Given that, it's a tad bit more sensible to place this within process.cpp, which keeps it visible only to the code that actually needs it.

|\ \ \ \ | |_|_|/ |/| | | kernel/{process, thread}: Amend behavior related to IDs
| * | | kernel/svc: Handle thread handles within GetProcessIdLioncash2018-12-191-10/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a thread handle is passed to svcGetProcessId, the kernel attempts to access the process ID via the thread's instance's owning process. Technically, this function should also be handling the kernel debug objects as well, however we currently don't handle those kernel objects yet, so I've left a note via a comment about it to remind myself when implementing it in the future.

| | | | | | | | | | | | | | | | | | | | | | | | 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.
| * | | kernel/svc: Correct output parameter for svcGetThreadIdLioncash2018-12-191-1/+1

|\ \ \ | | | | | | | | vm_manager/svc: Modify MemoryState enum, and correct error handling for svcQueryMemory
| * | | svc: Enable svcQueryProcessMemoryLioncash2018-12-122-1/+6
| | | | | | | | | | | | | | | | | | | | svcQueryProcessMemory is trivial to implement, given all the behavior necessary for it is present, it just needs a handler for it.
| * | | svc: Write out the complete MemoryInfo structure in QueryProcessMemoryLioncash2018-12-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the previous change, the memory writing was moved into the service function itself, however it still had a problem, in that the entire MemoryInfo structure wasn't being written out, only the first 32 bytes of it were being written out. We still need to write out the trailing two reference count members and zero out the padding bits. Not doing this can result in wrong behavior in userland code in the following scenario: MemoryInfo info; // Put on the stack, not quaranteed to be zeroed out. svcQueryMemory(&info, ...); if (info.device_refcount == ...) // Whoops, uninitialized read. This can also cause the wrong thing to happen if the user code uses std::memcmp to compare the struct, with another one (questionable, but allowed), as the padding bits are not guaranteed to be a deterministic value. Note that the kernel itself also fully zeroes out the structure before writing it out including the padding bits.
| * | | svc: Handle memory writing explicitly within QueryProcessMemoryLioncash2018-12-122-26/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Moves the memory writes directly into QueryProcessMemory instead of letting the wrapper function do it. It would be inaccurate to allow the handler to do it because there's cases where memory shouldn't even be written to. For example, if the given process handle is invalid. HOWEVER, if the memory writing is within the wrapper, then we have no control over if these memory writes occur, meaning in an error case, 68 bytes of memory randomly get trashed with zeroes, 64 of those being written to wherever the memory info address points to, and the remaining 4 being written wherever the page info address points to. One solution in this case would be to just conditionally check within the handler itself, but this is kind of smelly, given the handler shouldn't be performing conditional behavior itself, it's a behavior of the managed function. In other words, if you remove the handler from the equation entirely, does the function still retain its proper behavior? In this case, no. Now, we don't potentially trash memory from this function if an invalid query is performed.

| | | | | | | | | | | | | | | | | | | | | | | | The kernel returns a memory info instance with the base address set to the end of the address space, and the size of said block as 0 - address_space_end, it doesn't set both of said members to zero.

This also corrects the structures. PageInfo appears to only contain a 32-bit flags member, and the extra padding word in MemoryInfo isn't necessary.

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.

If a writable event cannot be found for the given handle, then an invalid handle error is returned. If a writable event is found, then it simply signals the event, as one would expect.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | svcCreateEvent operates by creating both a readable and writable event and then attempts to add both to the current process' handle table. If adding either of the events to the handle table fails, then the relevant error from the handle table is returned. If adding the readable event after the writable event to the table fails, then the writable event is removed from the handle table and the relevant error from the handle table is returned. Note that since we do not currently test resource limits, we don't check the resource limit table yet.

This also corrects ClearEvent() to check both kernel types like the kernel itself does.

To someone not familiar with the kernel, this might raise the question of "Ok, sounds nice, but doesn't this make it impossible to retrieve information about the current process?". No, it doesn't, because HandleTable instances in the kernel have the notion of a "pseudo-handle", where certain values allow the kernel to lookup objects outside of a given handle table. Currently, there's only a pseudo-handle for the current process (0xFFFF8001) and a pseudo-handle for the current thread (0xFFFF8000), so to retrieve the current process, one would just pass 0xFFFF8001 into svcGetInfo. The lookup itself in the handle table would be something like: template <typename T> T* Lookup(Handle handle) { if (handle == PSEUDO_HANDLE_CURRENT_PROCESS) { return CurrentProcess(); } if (handle == PSUEDO_HANDLE_CURRENT_THREAD) { return CurrentThread(); } return static_cast<T*>(&objects[handle]); } which, as is shown, allows accessing the current process or current thread, even if those two objects aren't actually within the HandleTable instance.

If this is violated, then ERR_INVALID_STATE is returned. e.g. Assume: current[Events] = 10; limit[Events] = 20; a call to this service function lowering the limit value to 10 would be fine, however, attempting to lower it to 9 in this case would cause an invalid state error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This kernel service function is essentially the exact same as svcGetResourceLimitLimitValue(), with the only difference being that it retrieves the current value for a given resource category using the provided resource limit handle, rather than retrieving the limiting value of that resource limit instance. Given these are exactly the same and only differ on returned values, we can extract the existing code for svcGetResourceLimitLimitValue() to handle both values.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This kernel service function retrieves the maximum allowable value for a provided resource category for a given resource limit instance. Given we already have the functionality added to the resource limit instance itself, it's sufficient to just hook it up. The error scenarios for this are: 1. If an invalid resource category type is provided, then ERR_INVALID_ENUM is returned. 2. If an invalid handle is provided, then ERR_INVALID_HANDLE is returned (bad thing goes in, bad thing goes out, as one would expect). If neither of the above error cases occur, then the out parameter is provided with the maximum limit value for the given category and success is returned.

Finally, it exits by providing the output parameter with the handle value for the ResourceLimit instance and returning that it was successful. Note: We do not return OUT_OF_RESOURCE because, if yuzu runs out of available memory, then new will currently throw. We *could* allocate the kernel instance with std::nothrow, however this would be inconsistent with how all other kernel objects are currently allocated.

| | | | | | | | | | | | | | | | | | | | | | | | | | So, one thing that's puzzled me is why the kernel seemed to *not* use the direct code address ranges in some cases for some service functions. For example, in svcMapMemory, the full address space width is compared against for validity, but for svcMapSharedMemory, it compares against 0xFFE00000, 0xFF8000000, and 0x7FF8000000 as upper bounds, and uses either 0x200000 or 0x8000000 as the lower-bounds as the beginning of the compared range. Coincidentally, these exact same values are also used in svcGetInfo, and also when initializing the user address space, so this is actually retrieving the ASLR extents, not the extents of the address space in general.

* thread: Make the scheduler pointer a regular pointerbalika0112018-10-052-4/+4
| | | | | | | | | | | | | | Conceptually, it doesn't make sense for a thread to be able to persist the lifetime of a scheduler. A scheduler should be taking care of the threads; the threads should not be taking care of the scheduler. If the threads outlive the scheduler (or we simply don't actually terminate/shutdown the threads), then it should be considered a bug that we need to fix. Attributing this to balika011, as they opened #1317 to attempt to fix this in a similar way, but my refactoring of the kernel code caused quite a few conflicts.
* kernel/thread: Make all instance variables privateLioncash2018-10-0411-187/+363
| | | | | | | | | | | | | | | | | | | | 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/svc: Implement svcGetThreadContext()Lioncash2018-09-303-2/+37
| | | | | | | | | Now that we have all of the rearranging and proper structure sizes in place, it's fairly trivial to implement svcGetThreadContext(). In the 64-bit case we can more or less just write out the context as is, minus some minor value sanitizing. In the 32-bit case we'll need to clear out the registers that wouldn't normally be accessible from a 32-bit AArch32 exectuable (or process).
* kernel/process: Add a data member to determine if a process is 64-bit or not.Lioncash2018-09-302-0/+11
| | | | | | | | | | | 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).

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel does the equivalent of the following check before proceeding: if (address + 0x8000000000 < 0x7FFFE00000) { return ERR_INVALID_MEMORY_STATE; } which is essentially what our IsKernelVirtualAddress() function does. So we should also be checking for this. The kernel also checks if the given input addresses are 4-byte aligned, however our Mutex::TryAcquire() and Mutex::Release() functions already handle this, so we don't need to add code for this case.

This is essentially a modernization change that should have occurred from the get-go.

* kernel: Eliminate kernel global stateLioncash2018-08-2932-405/+574
| | | | | | | | | | | | | | | | | | | | | | 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.

This essentially means, std::array, std::string, and std::vector can be used directly with this interface. The interface no longer forces you to solely use containers that dynamically allocate. To ensure our overloads play nice with one another, we only enable the container-based WriteBuffer if the argument is not a pointer, otherwise we fall back to the pointer-based one.

In this case, it boils down to how arithmetic conversions are performed before performing the comparison. If an unsigned value has a lesser conversion rank (aka smaller size) than the signed type being compared, then the unsigned value is promoted to the signed value (i.e. u8 -> s32 happens before the comparison). No sign-extension occurs here either. An alternative phrasing: Say we have a variable named core and it's given a value of -2. u8 core = -2; This becomes 254 due to the lack of sign. During integral promotion to the signed type, this still remains as 254, and therefore the condition will always be true, because no matter what value the u8 is given it will never be -2 in terms of 32 bits. Now, if one type was a s32 and one was a u32, this would be entirely different, since they have the same bit width (and the signed type would be converted to unsigned instead of the other way around) but would still have its representation preserved in terms of bits, allowing the comparison to be false in some cases, as opposed to being true all the time. --- We also get rid of two signed/unsigned comparison warnings while we're at it.

| | | | | | | | | | | | | | | | | | | | This situation may happen like so: Thread 1 with low priority calls WaitProcessWideKey with timeout. Thread 2 with high priority calls WaitProcessWideKey without timeout. Thread 3 calls SignalProcessWideKey - Thread 2 acquires the lock and awakens. - Thread 1 can't acquire the lock and is put to sleep with the lock owner being Thread 2. Thread 1's timeout expires, with the lock owner still being set to Thread 2.

| | | | | | | | | | | | | | | | | | This change makes for a clearer (less confusing) path of execution in the scheduler, now the code to execute when a thread awakes is closer to the code that puts the thread to sleep (WaitSynch1, WaitSynchN). It also allows us to implement the special wake up behavior of ReplyAndReceive without hacking up WaitObject::WakeupAllWaitingThreads. If savestates are desired in the future, we can change this implementation to one similar to the CoreTiming event system, where we first register the callback functions at startup and assign their identifiers to the Thread callback variable instead of directly assigning a lambda to the wake up callback variable.

* Kernel: Make WaitObjects share ownership of Threads waiting on themYuri Kunde Schlesner2015-02-026-12/+17
| | | | | | | | | | | | | | | | During normal operation, a thread waiting on an WaitObject and the object hold mutual references to each other for the duration of the wait. If a process is forcefully terminated (The CTR kernel has a SVC to do this, TerminateProcess, though no equivalent exists for threads.) its threads would also be stopped and destroyed, leaving dangling pointers in the WaitObjects. The solution is to simply have the Thread remove itself from WaitObjects when it is stopped. The vector of Threads in WaitObject has also been changed to hold SharedPtrs, just in case. (Better to have a reference cycle than a crash.)

| | | | | | | | | | | This handle manager more closely mirrors the behaviour of the CTR-OS one. In addition object ref-counts and support for DuplicateHandle have been added. Note that support for DuplicateHandle is still experimental, since parts of the kernel still use Handles internally, which will likely cause troubles if two different handles to the same object are used to e.g. wait on a synchronization primitive.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All service calls in the CTR OS return result codes indicating the success or failure of the call. Previous to this commit, Citra's HLE emulation of services and the kernel universally either ignored errors or returned dummy -1 error codes. This commit makes an initial effort to provide an infrastructure for error reporting and propagation which can be use going forward to make HLE calls accurately return errors as the original system. A few parts of the code have been updated to use the new system where applicable. One part of this effort is the definition of the `ResultCode` type, which provides facilities for constructing and parsing error codes in the structured format used by the CTR. The `ResultVal` type builds on `ResultCode` by providing a container for values returned by function that can report errors. It enforces that correct error checking will be done on function returns by preventing the use of the return value if the function returned an error code. Currently this change is mostly internal since errors are still suppressed on the ARM<->HLE border, as a temporary compatibility hack. As functionality is implemented and tested this hack can be eventually removed.
