class Connection

Defined at line 122 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

This represents a single connection from a client. All method calls on this class are serialized,

and are made on a dedicated connection thread.

magma_status_t MsdMapBuffer (Buffer & buffer, uint64_t gpu_va, uint64_t offset, uint64_t length, uint64_t flags)

magma_status_t MsdUnmapBuffer (Buffer & buffer, uint64_t gpu_va)

Defined at line 131 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

magma_status_t MsdBufferRangeOp (Buffer & buffer, uint32_t options, uint64_t start_offset, uint64_t length)

Defined at line 134 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

void MsdReleaseBuffer (Buffer & buffer, bool shutting_down)

Signals that the given |buffer| is no longer in use on the given |connection|. This must be

called for every connection associated with a buffer before the buffer is destroyed, or for

every buffer associated with a connection before the connection is destroyed.

In addition to handling client requests, this may be called when a connection is released,

in which case |shutting_down| is true and the implementation should not block.

void MsdSetNotificationCallback (NotificationHandler * handler)

Sets the callback to be used by a connection for various notifications.

This is called when a connection is created, and also called to unset

the callback before a connection is destroyed. A multithreaded

implementation must be careful to guard use of this callback to avoid

collision with possible concurrent destruction.

magma_status_t MsdCreatePerformanceCounterBufferPool (uint64_t pool_id, std::unique_ptr<PerfCountPool> * pool_out)

Defined at line 160 of file ../../src/graphics/magma/include/lib/magma_service/msd.h

magma_status_t MsdReleasePerformanceCounterBufferPool (std::unique_ptr<PerfCountPool> pool)

Releases the performance counter buffer pool. This driver must not send any notification with

the pool ID of this pool after it returns from this method.

magma_status_t MsdAddPerformanceCounterBufferOffsetToPool (PerfCountPool & pool, Buffer & buffer, uint64_t buffer_id, uint64_t buffer_offset, uint64_t buffer_size)

std::unique_ptr<Context> MsdCreateContext2 (uint64_t priority)

This method body can't be folded into the virtual method declaration above

because `Context` is an incomplete type at that point. In C++23,

std::unique_ptr

> can't be used in a _definition_ while T is incomplete

(only in _non-defining declarations_).
