This is used by svcControlProcessMemory and maps memory as Locked/AliasCode pair.
Also fixed a bug where map didn't apply specified permissions to the alias memory
* Kernel: reimplement memory management on physical FCRAM
* Kernel/Process: Unmap does not care the source memory permission
What game usually does is after mapping the memory, they reprotect the source memory as no permission to avoid modification there
* Kernel/SharedMemory: zero initialize new-allocated memory
* Process/Thread: zero new TLS entry
* Kernel: fix a bug where code segments memory usage are accumulated twice
It is added to both misc and heap (done inside HeapAlloc), which results a doubled number reported by svcGetProcessInfo. While we are on it, we just merge the three number misc, heap and linear heap usage together, as there is no where they are distinguished.
Question: is TLS page also added to this number?
* Kernel/SharedMemory: add more object info on mapping error
* Process: lower log level; SharedMemory: store phys offset
* VMManager: add helper function to retrieve backing block list for a range
Processes can keep some Thread/Timer object alive while the manager is already destructed, resulting use-after-free in Thread::Stop and Timer::dtor. To resolve this, the manager objects should be destructed after all related object destructed.
Fixes a bug where quiting citra causes crash while the game is using a Timer.
Fix a warning where class definition and forward declaration mismatch. CodeSet is a kernel object and have ctor/dtor/private members like others, so in convention it should be a class
To obtain the data, the LLEd mii selector of system version 11.8.0 was used.
In AppletManager::GlanceParameter, the following code was added to write the returned buffer data to a file:
if (parameter.buffer.size() == 132) {
std::u16string name(10, '\0');
std::memcpy(name.data(), parameter.buffer.data() + 0x26, 10 * sizeof(u16));
name = std::u16string(name.data());
FileUtil::IOFile file{fmt::format("{}.mii", Common::UTF16ToUTF8(name)), "wb"};
file.WriteBytes(parameter.buffer.data(), parameter.buffer.size());
}
Then "xxd -i" was used on the file to convert it to a hex array.
* Initial implementation
* Various fixes and new features
* Address some review comments
* Fixes
* Address more comments
* Use g_hle_lock
* Add more state checking, remove unneeded include
* Minor changes
Two functional change:
QueryProcessMemory uses the process passed from handle instead current_process
Thread::Stop() uses TLS from owner_process instead of current_process
This should be using the process instance retrieved within the function,
and not g_current_process, otherwise this is potentially comparing
iterators from unrelated vma_map instances (which is undefined
behavior).
The real console can't launch an Application directly from within another Application so it has to go through the Home Menu. We do not have such limitation and can directly launch the requested title.
* Core: pass down Core::System reference to all services
This has to be done at once due to unified interface used by HLE/LLE switcher
* apt: eliminate Core::System::GetInstance
* gpu_gsp: eliminate Core::System::GetInstance in service
* hid: eliminate Core::System::GetInstance
* nwm: eliminate Core::System::GetInstance
* err_f: eliminate Core::System::GetInstance
These functions are pretty much identical to BeginImportProgram and EndImportProgram.
We don't need to do anything special in EndImportProgramWithoutCommit and CommitImportPrograms because we don't need to implement the two-phase title installation that the 3DS uses to prevent corruption of the title.db.
FS subfiles are created with File::OpenSubFile, they have a start offset that must be added to all read/write operations.
The implementation in this commit is done using a new FileBackend that wraps the FS::File along with the start offset.
boost::static_pointer_cast for boost::intrusive_ptr (what SharedPtr is),
takes its parameter by const reference. Given that, it means that this
std::move doesn't actually do anything other than obscure what the
function's actual behavior is, so we can remove this. To clarify, this
would only do something if the parameter was either taking its argument
by value, by non-const ref, or by rvalue-reference.
This adds a clock init time field to the CTM header. The clock settings would be overridden when playing a movie. And when recording a movie, if the clock is set to System Time, it would be set to fixed init time at the current moment as well. In this way this keeps consistency with the RNG even if the user does just no setting.
This can just be a regular function, getting rid of the need to also
explicitly undef the define at the end of the file. Given FuncReturn()
was already converted into a function, it's #undef can also be removed.
Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.
We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
There were a few places where nested namespace specifiers weren't being
used where they could be within the service code. This amends that to
make the namespacing a tiny bit more compact.
While likely very uncommon, this sanitizes the input and does nothing in
the event of the length being equal to or less than zero, avoiding
constructing a std::string when there's no need to. It also avoids an
out-of-memory scenario, as a negative value would wrap around to its
equivalent unsigned representation in std::string's constructor.
e.g. If someone was silly and a length of -1 was specified, this would
make a string with a length of 0xFFFFFFFFFFFFFFFF on a 64-bit platform,
which will obviously eventually fail due to the allocation being way too
large.
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class
which is within the Kernel namespace.
Despite being covered by a global mutex, we should still ensure that the
class handles its reference counts properly. This avoids potential
shenanigans when it comes to data races.
Given this is the root object that drives quite a bit of the kernel
object hierarchy, ensuring we always have the correct behavior (and no
races) is a good thing.
Shared fonts is no different from any other system archives, and there is not really any point to make a separate status for it. This also fixes the incorrect error message that was introduced when I made the UI text improvements.
* Add setting to switch between a fixed start time and the system time
Add clock settings to SDL
Make clock configureable in qt
Add a SharedPage handler class
Init shared_page_handler for tests
* kernel/event: Make data members private
Instead we can simply provide accessors to the required data instead of
giving external read/write access to the variables directly.
* fix compile error
* client_port: Make all data members private
These members don't need to be entirely exposed, we can instead expose
an API to operate on them without directly needing to mutate them
We can also guard against overflow/API misuse this way as well, given
active_sessions is an unsigned value.
* make the condition an assert
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
General moving to keep kernel object types separate from the direct
kernel code. Also essentially a preliminary cleanup before eliminating
global kernel state in the kernel code.
* NWM_UDS: use sizeof(<var being used>) instead of hard-coded type
Intend to fix#4090.
` node_map.node.second` type was changed to `u16` in #3985. However the type change wasn't reflected here. Should have used variable name instead to automatically do type change
* NWM_UDS: ... and also the node.first one
* NWM_UDS: ... and here
* Network: bump version because we changed UDS packet layout
* Update nwm_uds.cpp
