Lioncash cd6ea98890 k_scheduler: Mark KScopedSchedulerLock as [[nodiscard]]
Prevents logic bugs like:

KScopedSchedulerLock{kernel};

instead of:

KScopedSchedulerLock lk{kernel};

from slipping through.

ameerj c7a0ebbba7 kernel: Increase event and session counts
12.x increased the number of available sessions and event resource counts

Lioncash 840fadc3e4 svc: Expand SVC tables
12.x expanded the range of SVC entries from 0x7F to 0xBF (with all new
entries being unused), so we can expand it to also match.
2021-04-07 00:55:33 -04:00
Lioncash 7737db89aa process_capability: Handle extended SVC range
12.x extended the range of SVC IDs, so we need to expand the range of
bits that need to be tested.

The upside of this is that we can eliminate a range check, given the
whole range is used.

ameerj 0d9fb9ca27 kernel: Fix resource release exception on exit
After rewriting the resource limit, objects releasing reserved resources require a live kernel instance.
This commit fixes exceptions that occur due to the kernel being destroyed before some objects released their resources, allowing for a graceful exit.

Chloe e62886ead0 kernel: Unify result codes (#5890)
* kernel: Unify result codes

Drop the usage of ERR_NAME convention in kernel for ResultName. Removed seperation between svc_results.h & errors.h as we mainly include both most of the time anyways.

Lioncash 4431b499d0 k_priority_queue: Resolved reserved identifier
An identifier containing a starting underscore followed by a capital
letter is reserved by the standard. It's trivial to avoid this by moving
the underscore to the end of the identifier.

While the likelihood of clashing here being minimal, we can turn a
"should not break" scenario into a definitive "will not break" one, so
why not?.

ReinUsesLisp 8bfa4d6dbf core/memory: Read and write page table atomically
Squash attributes into the pointer's integer, making them an uintptr_t
pair containing 2 bits at the bottom and then the pointer. These bits
are currently unused thanks to alignment requirements.

Configure Dynarmic to mask out these bits on pointer reads.

While we are at it, remove some unused attributes carried over from
Citra.

Read/Write and other hot functions use a two step unpacking process that
is less readable to stop MSVC from emitting an extra AND instruction in
the hot path:

 mov         rdi,rcx
 shr         rdx,0Ch

comex 8be4bd5104 k_priority_queue: Fix concepts use
- For `std::same_as`, add missing include of `<concepts>`.

- For `std::convertible_to`, create a replacement in `common/concepts.h`
  and use that instead.

  This would also be found in `<concepts>`, but unlike `std::same_as`,
  `std::convertible_to` is not yet implemented in libc++, LLVM's STL
  implementation - not even in master.  (In fact, `std::same_as` is the
  *only* concept currently implemented.  For some reason.)

comex 0049fbaa9e Add missing include of "core/hle/kernel/kernel.h"
This is needed as the header invokes methods on KernelCore.

ameerj ca41363261 svc: demote SleepThread log to LOG_TRACE
This log is called often, and introduces a lot of noise when debug logging is enabled, making it difficult to see other debug logs.

Lioncash a4f07e1cc4 svc: Remove unnecessary casts
Simplifies and removes some casts. In all cases, these were generally
widening from a 32-bit unsigned type to a 64-bit unsigned type, so no
information would be lost from the conversion.

Lioncash 8f135703dc core: Remove unnecessary enum casts in log calls
Follows the video core PR. fmt doesn't require casts for enum classes
anymore, so we can remove quite a few casts.

comex 086238f1ac Fix "explicitly defaulted but implicitly deleted" warning
`PhysicalCore`'s move assignment operator was declared as `= default`,
but was implicitly deleted because `PhysicalCore` has fields
of reference type.  Switch to explicitly deleting it to avoid a Clang
warning.

The move *constructor* is still defaulted, and is required to exist due
to the use of `std::vector<PhysicalCore>`.
