nvhost_gpu: Don't over copy IoctlSubmitGpfifo.
|
|
|
|
Rather than use global state, we can simply pass the instance into the
NVFlinger instance directly.
|
|
The only reason this wasn't a compilation error is because we use
little-endian systems.
|
|
|
|
All calling code assumes that the rasterizer will be in a valid state,
which is a totally fine assumption. The only way the rasterizer wouldn't
be is if initialization is done incorrectly or fails, which is checked
against in System::Init().
|
|
We move the initialization of the renderer to the core class, while
keeping the creation of it and any other specifics in video_core. This
way we can ensure that the renderer is initialized and doesn't give
unfettered access to the renderer. This also makes dependencies on types
more explicit.
For example, the GPU class doesn't need to depend on the
existence of a renderer, it only needs to care about whether or not it
has a rasterizer, but since it was accessing the global variable, it was
also making the renderer a part of its dependency chain. By adjusting
the interface, we can get rid of this dependency.

Passing nullptr to memcpy is undefined behavior.
|
|
Avoids copies from being made, since the string is only ever used for
lookup, the data is never transfered anywhere.
Ideally, we'd use a std::string_view here, but devices is a
std::unordered_map, not a std::map, so we can't use heterogenous lookup
here.
|
|
Avoids unnecessary reference count increments and decrements.
In one case, we don't need to make a shared_ptr copy at all,
just to call a member function.
|
|
This behaves quite similarly to the SubmitGPFIFO command. Referenced from Ryujinx.
Many thanks to @gdkchan for investigating this!

hle/service: Make constructors explicit where applicable
|
|
Prevents implicit construction and makes these lingering non-explicit
constructors consistent with the rest of the other classes in services.
|
|
This is only ever used as a lookup into the device map, so we don't need to
take the std::string instance by value here.
|

|
|
Settings are only used when RMOS_SET_PRODUCTION_MODE is set to 0.
If production mode is set, the error code 0x30006 is returned instead

unmapped from the GPU's MMU.
|
|
This behavior is confirmed by reverse engineering.

* add IoctlCommands with their params in nvidia_ctrl_gpu.h
* add function related to the changes done previously
* fix clang-format
* delete trailing whitespace
* correct mistake

Services/nvdrv: add '/dev/nvhost-nvdec' device

Stub NVGPU_IOCTL_CHANNEL_SET_TIMEOUT
|
|
We have no clue on what this actually does yet so stubbing it since it's just input only should be fine for now
|
|
Used in Nintendo Labo ToyCon 1&2
|
|
according to the changes made previously
|
|
|
|
|
|
* Implemented NVHOST_IOCTL_CHANNEL_GET_WAITBASE
struct + 4 seems to be hard coded at 0 and struct + 0 seems to be ignored?
* IocGetWaitbase -> IocChannelGetWaitbaseCommand
* Added super late fixes

It releases a reference to an nvmap object
|
|
It removes a mapping previously created with the MapBufferEx ioctl.

|
This makes the formatting expectations more obvious (e.g. any zero padding specified
is padding that's entirely dedicated to the value being printed, not any pretty-printing
that also gets tacked on).

Nvdrv/nvhost-as-gpu: Implemented the ioctl REMAP command.

|
already been allocated.
Also added a consistency check and a comment for the case when the object id is different than its handle. The real nvservices doesn't make a distinction between ids and handles, each object gets an unique handle which doubles as its id.
|
|
It takes a previously-reserved (AllocateSpace) GPU memory address and maps it to the address of the nvmap object passed to Remap.
