kernel/process: Make CodeSet a regular non-inherited object

svc: Fix typos in sanitizing checks for MapMemory/UnmapMemory
|
|
Fixed incorrect types for svcBreak
|
|
These only exist to ferry data into a Process instance and end up going
out of scope quite early. Because of this, we can just make it a plain
struct for holding things and just std::move it into the relevant
function. There's no need to make this inherit from the kernel's Object
type.

Passing an invalid nmap handle to Remap should throw an error

thread: Remove unnecessary memset from ResetThreadContext()

Added error codes for nvmap
|

Regular value initialization is adequate here for zeroing out data. It
also has the benefit of not invoking undefined behavior if a non-trivial
type is ever added to the struct for whatever reason.

svc: Add missing address range sanitizing checks to MapMemory/UnmapMemory
|
|
|
|
Added error for invalid nmap handles
|
|
|
|
Used by sonic ages

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.
|
|
Fixed assertion due to CountAddOnContent & Casting warnings
|
|
Hardware tests show that trying to unmap an unmapped buffer already should always succeed. Hardware test was tested up to 32 iterations of attempting to unmap
|
|
Word count should be 3 since we're pushing a result code and a u32.
Also fixed up compiler warnings due to casting

loader: Add support for packed updates

This will allow us to easily remove the use of "NFC" in "System"
|
|
This was the result of a typo accidentally introduced in
e51d715700a35a8f14e5b804b6f7553c9a40888b. This restores the previous
correct behavior.
The behavior with the reference was incorrect and would cause some games
to fail to boot.
|

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 private
|
|
|
|
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.

aoc_u: Fix edge case with DLC that causes breaks

services/fsp_srv: Amend service function table
|
|
In some games (Splatoon 2 and Splatoon 2 Splatfest World Premiere, notably), pass offset=0 and count=2047 into the ListAddOnContent method which should return all DLCs for the current title. The (presumably) intended behavior is to successfully return a empty array but because of a < v. <= in an if statement, a failure error code was returned causing these games to svcBreak. This fixes that if statement.

|
Adds new functions that have been given names to the table. Information
is based off what is provided on Switchbrew.

Amends the lbl service table to include new names of functions that were
added to Switchbrew.

Implement ISystemDisplayService::GetDisplayMode
|
|
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).
|
|
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).
|
|
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.
