From 2a9d17b7e7244da62f1d05fce575a4d78e60cd50 Mon Sep 17 00:00:00 2001 From: ReinUsesLisp Date: Fri, 3 Jul 2020 22:00:30 -0300 Subject: [PATCH 1/2] maxwell_dma: Rename registers to match official docs and reorder Rename registers in the MaxwellDMA class to match Nvidia's official documentation. This one can be found here: https://github.com/NVIDIA/open-gpu-doc/blob/master/classes/dma-copy/clb0b5.h While we are at it, reorganize the code in MaxwellDMA to be separated in different functions. --- src/video_core/engines/maxwell_dma.cpp | 322 +++++++++++----------- src/video_core/engines/maxwell_dma.h | 368 ++++++++++++++----------- 2 files changed, 379 insertions(+), 311 deletions(-) diff --git a/src/video_core/engines/maxwell_dma.cpp b/src/video_core/engines/maxwell_dma.cpp index 01d7df405..28faad9ff 100644 --- a/src/video_core/engines/maxwell_dma.cpp +++ b/src/video_core/engines/maxwell_dma.cpp @@ -14,50 +14,44 @@ namespace Tegra::Engines { +using namespace Texture; + MaxwellDMA::MaxwellDMA(Core::System& system, MemoryManager& memory_manager) : system{system}, memory_manager{memory_manager} {} void MaxwellDMA::CallMethod(u32 method, u32 method_argument, bool is_last_call) { - ASSERT_MSG(method < Regs::NUM_REGS, - "Invalid MaxwellDMA register, increase the size of the Regs structure"); + ASSERT_MSG(method < NUM_REGS, "Invalid MaxwellDMA register"); regs.reg_array[method] = method_argument; -#define MAXWELLDMA_REG_INDEX(field_name) \ - (offsetof(Tegra::Engines::MaxwellDMA::Regs, field_name) / sizeof(u32)) - - switch (method) { - case MAXWELLDMA_REG_INDEX(exec): { - HandleCopy(); - break; + if (method == offsetof(Regs, launch_dma) / sizeof(u32)) { + Launch(); } - } - -#undef MAXWELLDMA_REG_INDEX } void MaxwellDMA::CallMultiMethod(u32 method, const u32* base_start, u32 amount, u32 methods_pending) { - for (std::size_t i = 0; i < amount; i++) { + for (size_t i = 0; i < amount; ++i) { CallMethod(method, base_start[i], methods_pending - static_cast(i) <= 1); } } -void MaxwellDMA::HandleCopy() { +void MaxwellDMA::Launch() { LOG_TRACE(HW_GPU, "Requested a DMA copy"); - const GPUVAddr source = regs.src_address.Address(); - const GPUVAddr dest = regs.dst_address.Address(); - // TODO(Subv): Perform more research and implement all features of this engine. - ASSERT(regs.exec.enable_swizzle == 0); - ASSERT(regs.exec.query_mode == Regs::QueryMode::None); - ASSERT(regs.exec.query_intr == Regs::QueryIntr::None); - ASSERT(regs.exec.copy_mode == Regs::CopyMode::Unk2); - ASSERT(regs.dst_params.pos_x == 0); - ASSERT(regs.dst_params.pos_y == 0); + const LaunchDMA& launch = regs.launch_dma; + ASSERT(launch.remap_enable == 0); + ASSERT(launch.semaphore_type == LaunchDMA::SemaphoreType::NONE); + ASSERT(launch.interrupt_type == LaunchDMA::InterruptType::NONE); + ASSERT(launch.data_transfer_type == LaunchDMA::DataTransferType::NON_PIPELINED); + ASSERT(regs.dst_params.origin.x == 0); + ASSERT(regs.dst_params.origin.y == 0); - if (!regs.exec.is_dst_linear && !regs.exec.is_src_linear) { + const bool is_src_pitch = launch.src_memory_layout == LaunchDMA::MemoryLayout::PITCH; + const bool is_dst_pitch = launch.dst_memory_layout == LaunchDMA::MemoryLayout::PITCH; + + if (!is_src_pitch && !is_dst_pitch) { // If both the source and the destination are in block layout, assert.
