David Marcec 442900456e memory_manager: Remove useless assertion 
num_pages is an std::size_t. It will always be >= 0
 2020-06-25 16:35:58 +10:00
David Marcec df001e73c2 Mark invalid IPC buffers as ASSERT_OR_EXECUTE_MSG 
Previously if applications would send faulty buffers(example homebrew) it would lead to us returning uninitalized data. Switching from ASSERT_MSG to ASSERT_OR_EXECUTE_MSG allows us to have a fail safe to prevent crashes but also continue execution without introducing undefined behavior

 2020-06-12 22:30:19 -04:00
David Marcec 97ad3cd3ee kernel: Account for system resource size for memory usage 
GetTotalPhysicalMemoryAvailableWithoutSystemResource & GetTotalPhysicalMemoryUsedWithoutSystemResource seem to subtract the resource size from the usage.

kernel/memory: Resolve several compiler warnings
 2020-05-05 15:41:18 -04:00
Lioncash 12b81f2581 kernel/memory: Remove #pragma once within cpp file 
This isn't necessary in a cpp file and will cause warnings on clang.
 2020-05-03 13:42:07 -04:00
Lioncash 0bf0d27552 kernel/memory: Remove unused includes

Prevents variable name clashing.

Lioncash a93929b23a kernel/memory: Amend potential encoding warnings 
While èis generally representable in some language encodings, in some
it isn't and will result in compilation warnings occurring. To remain
friendly with other language's codepages on Windows, we normalize it to
an ASCII e.
 2020-05-03 13:01:03 -04:00
Lioncash ccfac6d992 hle_ipc: Eliminate core memory globals 
We can just pass the required instances into the constructor of the
request, eliminating all usages of the global system accessor.

Lioncash 918b439e26 readable_event: Remove unnecessary semicolon in Signal()

While we're at it, we can invert the branch to form a guard clause,
unindenting all of the contained code.

physical_core: Make use of std::make_unique instead of std::make_shared in ctor
 2020-04-28 21:38:02 -04:00
David Marcec 45ece975bf kernel: Bad GetInfo ids should not be marked as stubs 
As we currently match hardware and don't return a successful result, these should be marked as errors instead of warnings and as stubs.

 2020-04-24 23:22:26 -04:00
Lioncash dca9c90af3 physical_core: Make use of std::make_unique instead of std::make_shared in ctor 
We can also allow unicorn to be constructed in 32-bit mode or 64-bit
mode to satisfy the need for both interpreter instances.

Allows this code to compile successfully of non x86-64 architectures.

These were lost in the re-implementation of the virtual memory manager.
 2020-04-23 18:12:04 -04:00
Lioncash 2fc4351547 svc: Remove unused variable 
Since the VMM refactor, this is no longer used or needed.
 2020-04-23 17:53:26 -04:00
Lioncash a881161d3c page_table: Remove unused captures 
Any time the lambda function is called, the permission being used in the
capture would be passed in as an argument to the lambda, so the capture
is unnecessary.

Lioncash ac3ff8c9ba memory/slab_heap: Make use of static_cast over reinterpret_cast 
Casting from void* with static_cast is permitted by the standard, so we
can just make use of that instead.

Lioncash f8fe53c9f9 hle_ipc: Remove std::size_t casts where applicable 
These were added in the change that enabled -Wextra on linux builds so
as not to introduce interface changes in the same change as a
build-system flag addition.

Now that the flags are enabled, we can freely change the interface to
make these unnecessary.
 2020-04-16 22:02:10 -04:00
Lioncash 02e095313a CMakeLists: Specify -Wextra on linux builds 
Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.

We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).

While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.
 2020-04-15 21:33:46 -04:00
Lioncash 6ea751d910 CMakeLists: Make -Wreorder a compile-time error 
This can result in silent logic bugs within code, and given the amount
of times these kind of warnings are caused, they should be flagged at
compile-time so no new code is submitted with them.
