kernel/shared_memory: Make data members private, plus minor interface changes
|
|
am: Implement HLE software keyboard applet
|
|
Cleans out the citra/3DS-specific implementation details that don't
apply to the Switch. Sets the stage for implementing ResourceLimit
instances properly.
While we're at it, remove the erroneous checks within CreateThread() and
SetThreadPriority(). While these are indeed checked in some capacity,
they are not checked via a ResourceLimit instance.
In the process of moving out Citra-specifics, this also replaces the
system ResourceLimit instance's values with ones from the Switch.

reference rather than as a pointer
Both member functions assume the passed in target process will not be
null. Instead of making this assumption implicit, we can change the
functions to be references and enforce this at the type-system level.

svc: ResetSignal is not stubbed

Seems to be used and created identically to SharedMemory, so just reuse that.

Similar to PR 1706, which cleans up the error codes for the filesystem
code, but done for the kernel error codes. This removes the ErrCodes
namespace and specifies the errors directly. This also fixes up any
straggling lines of code that weren't using the named error codes where
applicable.

* svcBreak now dumps information from the debug buffer passed
info1 and info2 seem to somtimes hold an address to a buffer, this is usually 4 bytes or the size of the int and contains an error code. There's other circumstances where it can be something different so we hexdump these to examine them at a later date.
* Addressed comments

Nothing from this enum is intended to be used outside of this function.
|

This retrieves:
if (curr_thread == handle_thread) {
result = total_thread_ticks + (hardware_tick_count - last_context_switch_ticks);
} else if (curr_thread == handle_thread && sub_id == current_core_index) {
result = hardware_tick_count - last_context_switch_ticks;
}

Like with the previous change, the kernel doesn't return NOT_AUTHORIZED
here. It returns INVALID_THREAD_PRIORITY.
|
|
priorities in SetThreadPriority()
All priority checks are supposed to occur before checking the validity
of the thread handle, we're also not supposed to return
ERR_NOT_AUTHORIZED here.

Added break types to svcBreak

kernel/process: Make the handle table per-process
|
|
|
|
There seems to be more such as type 1, and 2. Unsure what these currently are but when a game hits them we can investigate and add the rest
|
|
In the kernel, there isn't a singular handle table that everything gets
tossed into or used, rather, each process gets its own handle table that
it uses. This currently isn't an issue for us, since we only execute one
process at the moment, but we may as well get this out of the way so
it's not a headache later on.
|
|
This should be comparing against the queried process' vma_map, not the
current process'. The only reason this hasn't become an issue yet is we
currently only handle one process being active at any time.

svc: Add missing sanitizing checks for MapSharedMemory/UnmapSharedMemory
|
|
svcArbitrateLock/svcArbitrateUnlock
The kernel itself checks whether or not the provided addresses are word
aligned before continuing, so we should be doing the same.
|
|
Aligning on 4KB pages isn't a Switch-specific thing, so this can be
moved to common so it can be used with other things as well.
|
|
Now that the changes clarifying the address spaces has been merged, we
can wrap the checks that the kernel performs when mapping shared memory
(and other forms of memory) into its own helper function and then use
those within MapSharedMemory and UnmapSharedMemory to complete the
sanitizing checks that are supposed to be done.

svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo()
|
|
|
|
svcGetInfo()
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.

svc: Implement svcGetProcessInfo
|
|
This should help diagnose crashes easier and prevent many users thinking that a game is still running when in fact it's just an audio thread still running(this is typically not killed when svcBreak is hit since the game expects us to do this)
|
|
A fairly basic service function, which only appears to currently support
retrieving the process state. This also alters the ProcessStatus enum to
contain all of the values that a kernel process seems to be able of
reporting with regards to state.

svc: Fix typos in sanitizing checks for MapMemory/UnmapMemory
|
|
Fixed incorrect types for svcBreak
|
|
|
|
This adds the missing address range checking that the service functions
do before attempting to map or unmap memory. Given that both service
functions perform the same set of checks in the same order, we can wrap
these into a function and just call it from both functions, which
deduplicates a little bit of code.
|
|
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).
|
|
signal_debugger seems like a more fitting name
|
|
svcBreak reason should be a u32, not a u64.
|
|
|
|
|
|
When loading NROs, svcBreak is called to signal to the debugger that a new "module" is loaded. As no debugger is technically attached we shouldn't be killing the programs execution.
