Shahbaz Youssefi c3a1cae4 2024-04-15T14:58:55 Use angle::SimpleMutex everywhere in libGLESv2 Only cases left that use std::mutex are: - Share group and the context ErrorSet mutexes as they need try_lock() - Anywhere mutexes are used in conjunction with std::condition_variables (as they explicitly require std::mutex) Bug: angleproject:8667 Change-Id: Ib6d68938b0886f9e7c43e023162557990ecfb300 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5453294 Reviewed-by: Roman Lavrov <romanl@google.com> Reviewed-by: Charlie Lao <cclao@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
Igor Nazarov cae00d9b 2023-01-17T18:44:48 Vulkan: Cleanup shared ring buffer cmd alloc feature. Changes: - Simplified "SharedCommandBlockPool" interface. Removed "ptrOut" and "usesCommandHeaderSizeForOffsetOut" parameters, because "headerOut" has exactly the same value. - Refactoring of "SharedCommandBlockPool" classes. Some public methods made private, inline, or moved into ".cpp". - Replace some getters with more specific/restrictive methods: - "RingBufferAllocatorBuffer::getStorageSize()" -> "isEmpty()" - "CommandBufferHelperCommon::getAllocator()" -> "hasAllocatorLinks()" - Added extra ASSERT()s. - fixed typo "kMinRingBufferAllocatio(r)Capacity" - other minor modifications.

Amirali Abdolrashidi 684ff60b 2022-06-21T10:52:31 Vulkan: Add shared ring buffer cmd alloc feature * Added RingBufferAllocator.cpp with implementation. * Main classes: * RingBufferAllocator (fast allocation with bulk deallocation) * SharedRingBufferAllocator (wrapper to help with shared use and multiple threads) * Implemented "angle_enable_vulkan_shared_ring_buffer_cmd_alloc" feature. (Disabled by default) * Details (from the original CL) * The angle::PoolAllocator replaced with angle::RingBufferAllocator. * Before, there was separate angle::PoolAllocator per each CommandBufferHelper. Now, a single angle::RingBufferAllocator is shared between multiple CommandBufferHelper objects. * Commands data from multiple CommandBufferHelpers is tightly packed without fragmentation. * Significantly less memory overhead, observed with enabled async queue. * Moved the parts of the code related to the allocators into the classes in the new AllocatorHelperPool and AllocatorHelperRing files for better management. The allocator can be switched by changing the following BUILD flag: `angle_enable_vulkan_shared_ring_buffer_cmd_alloc` * It is connected to the following macro: ANGLE_ENABLE_VULKAN_SHARED_RING_BUFFER_CMD_ALLOC * The two main allocator classes in each file are aliased as: * SecondaryCommandBlockAllocator (in CommandBufferHelper objects) * SecondaryCommandBlockPool (in SecondaryCommandBuffer) * Also added placeholder functions for VulkanSecondaryCommandBuffer. * Added descriptions regarding the two allocators. * renderer/vulkan/doc/Allocators.md Credit: Original CL authored by Igor Nazarov <i.nazarov@samsung.com> Bug: angleproject:6401 Bug: b/256666069 Change-Id: I0f24793eef6334bf4ff8e327b9665338807dad37 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3715968 Reviewed-by: Charlie Lao <cclao@google.com> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Commit-Queue: Amirali Abdolrashidi <abdolrashidi@google.com>
