The DRM is extensible via the use of small device-specific modules - that rely extensively on the API exported by the DRM module. - - -Documentation on the DRI is available from: - http://dri.freedesktop.org/wiki/Documentation - http://sourceforge.net/project/showfiles.php?group_id=387 - http://dri.sourceforge.net/doc/ - -For specific information about kernel-level support, see: - - The Direct Rendering Manager, Kernel Support for the Direct Rendering - Infrastructure - http://dri.sourceforge.net/doc/drm_low_level.html - - Hardware Locking for the Direct Rendering Infrastructure - http://dri.sourceforge.net/doc/hardware_locking_low_level.html - - A Security Analysis of the Direct Rendering Infrastructure - http://dri.sourceforge.net/doc/security_low_level.html diff --git a/drivers/gpu/drm/amd/amdkfd/Kconfig b/drivers/gpu/drm/amd/amdkfd/Kconfig new file mode 100644 index 0000000..8dfac37 --- /dev/null +++ b/drivers/gpu/drm/amd/amdkfd/Kconfig @@ -0,0 +1,9 @@ +# +# Heterogenous system architecture configuration +# + +config HSA_AMD + tristate "HSA kernel driver for AMD GPU devices" + depends on DRM_RADEON && AMD_IOMMU_V2 && X86_64 + help + Enable this if you want to use HSA features on AMD GPU devices. diff --git a/drivers/gpu/drm/amd/amdkfd/Makefile b/drivers/gpu/drm/amd/amdkfd/Makefile new file mode 100644 index 0000000..be6246d --- /dev/null +++ b/drivers/gpu/drm/amd/amdkfd/Makefile @@ -0,0 +1,14 @@ +# +# Makefile for Heterogenous System Architecture support for AMD GPU devices +# + +ccflags-y := -Iinclude/drm -Idrivers/gpu/drm/amd/include/ + +amdkfd-y := kfd_module.o kfd_device.o kfd_chardev.o kfd_topology.o \ + kfd_pasid.o kfd_doorbell.o kfd_flat_memory.o \ + kfd_process.o kfd_queue.o kfd_mqd_manager.o \ + kfd_kernel_queue.o kfd_packet_manager.o \ + kfd_process_queue_manager.o kfd_device_queue_manager.o \ + kfd_interrupt.o + +obj-$(CONFIG_HSA_AMD) += amdkfd.o diff --git a/drivers/gpu/drm/amd/amdkfd/cik_regs.h b/drivers/gpu/drm/amd/amdkfd/cik_regs.h new file mode 100644 index 0000000..607fc5c --- /dev/null +++ b/drivers/gpu/drm/amd/amdkfd/cik_regs.h @@ -0,0 +1,221 @@ +/* + * Copyright 2014 Advanced Micro Devices, Inc. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

The method we take for 64b mode is + * to map the full 40b GPUVM address space into the hole of the 64b address + * space. + + * The GPUVM_Base/GPUVM_Limit defines the aperture in the 64b space where we + * direct requests to be translated via GPUVM page tables instead of the + * IOMMU path. + * + * + * 64b to 49b Address conversion + * + * Note that there are still significant portions of unused regions (holes) + * in the 64b address space even for the GPU. There are several places in + * the pipeline (sw and hw), we wish to compress the 64b virtual address + * to a 49b address. This 49b address is constituted of an “ATC” bit + * plus a 48b virtual address. This 49b address is what is passed to the + * translation hardware. ATC==0 means the 48b address is a GPUVM address + * (max of 2^40 – 1) intended to be translated via GPUVM page tables. + * ATC==1 means the 48b address is intended to be translated via IOMMU + * page tables. + * + * A 64b pointer is compared to the apertures that are defined (Base/Limit), in + * this case the GPUVM aperture (red) is defined and if a pointer falls in this + * aperture, we subtract the GPUVM_Base address and set the ATC bit to zero + * as part of the 64b to 49b conversion. + * + * Where this 64b to 49b conversion is done is a function of the usage. + * Most GPU memory access is via memory objects where the driver builds + * a descriptor which consists of a base address and a memory access by + * the GPU usually consists of some kind of an offset or Cartesian coordinate + * that references this memory descriptor. This is the case for shader + * instructions that reference the T# or V# constants, or for specified + * locations of assets (ex. the shader program location). In these cases + * the driver is what handles the 64b to 49b conversion and the base + * address in the descriptor (ex. V# or T# or shader program location) + * is defined as a 48b address w/ an ATC bit. For this usage a given + * memory object cannot straddle multiple apertures in the 64b address + * space. For example a shader program cannot jump in/out between ATC + * and GPUVM space. + * + * In some cases we wish to pass a 64b pointer to the GPU hardware and + * the GPU hw does the 64b to 49b conversion before passing memory + * requests to the cache/memory system. This is the case for the + * S_LOAD and FLAT_* shader memory instructions where we have 64b pointers + * in scalar and vector GPRs respectively. + * + * In all cases (no matter where the 64b -> 49b conversion is done), the gfxip + * hardware sends a 48b address along w/ an ATC bit, to the memory controller + * on the memory request interfaces. + * + * <client>_MC_rdreq_atc // read request ATC bit + * + * 0 : <client>_MC_rdreq_addr is a GPUVM VA + * + * 1 : <client>_MC_rdreq_addr is a ATC VA + * + * + * “Spare” aperture (APE1) + * + * We use the GPUVM aperture to differentiate ATC vs. GPUVM, but we also use + * apertures to set the Mtype field for S_LOAD/FLAT_* ops which is input to the + * config tables for setting cache policies. The “spare” (APE1) aperture is + * motivated by getting a different Mtype from the default. + * The default aperture isn’t an actual base/limit aperture; it is just the + * address space that doesn’t hit any defined base/limit apertures. + * The following diagram is a complete picture of the gfxip7.x SUA apertures. + * The APE1 can be placed either below or above + * the hole (cannot be in the hole). + * + * + * General Aperture definitions and rules + * + * An aperture register definition consists of a Base, Limit, Mtype, and + * usually an ATC bit indicating which translation tables that aperture uses. + * In all cases (for SUA and DUA apertures discussed later), aperture base + * and limit definitions are 64KB aligned. + * + * <ape>_Base[63:0] = { <ape>_Base_register[63:16], 0x0000 } + * + * <ape>_Limit[63:0] = { <ape>_Limit_register[63:16], 0xFFFF } + * + * The base and limit are considered inclusive to an aperture so being + * inside an aperture means (address >= Base) AND (address <= Limit). + * + * In no case is a payload that straddles multiple apertures expected to work. + * For example a load_dword_x4 that starts in one aperture and ends in another, + * does not work. For the vector FLAT_* ops we have detection capability in + * the shader for reporting a “memory violation” back to the + * SQ block for use in traps. + * A memory violation results when an op falls into the hole, + * or a payload straddles multiple apertures. The S_LOAD instruction + * does not have this detection. + * + * Apertures cannot overlap. + * + * + * + * HSA32 - ATC/IOMMU 32b + * + * For HSA32 mode, the pointers are interpreted as 32 bits and use a single GPR + * instead of two for the S_LOAD and FLAT_* ops. The entire GPUVM space of 40b + * will not fit so there is only partial visibility to the GPUVM + * space (defined by the aperture) for S_LOAD and FLAT_* ops. + * There is no spare (APE1) aperture for HSA32 mode. + * + * + * GPUVM 64b mode (driver model) + * + * This mode is related to HSA64 in that the difference really is that + * the default aperture is GPUVM (ATC==0) and not ATC space. + * We have gfxip7.x hardware that has FLAT_* and S_LOAD support for + * SUA GPUVM mode, but does not support HSA32/HSA64. + * + * + * Device Unified Address - DUA + * + * Device unified address (DUA) is the name of the feature that maps the + * Shared(LDS) memory and Private(Scratch) memory into the overall address + * space for use by the new FLAT_* vector memory ops. The Shared and + * Private memories are mapped as apertures into the address space, + * and the hardware detects when a FLAT_* memory request is to be redirected + * to the LDS or Scratch memory when it falls into one of these apertures. + * Like the SUA apertures, the Shared/Private apertures are 64KB aligned and + * the base/limit is “in” the aperture. For both HSA64 and GPUVM SUA modes, + * the Shared/Private apertures are always placed in a limited selection of + * options in the hole of the 64b address space. For HSA32 mode, the + * Shared/Private apertures can be placed anywhere in the 32b space + * except at 0. + * + * + * HSA64 Apertures for FLAT_* vector ops + * + * For HSA64 SUA mode, the Shared and Private apertures are always placed + * in the hole w/ a limited selection of possible locations. The requests + * that fall in the private aperture are expanded as a function of the + * work-item id (tid) and redirected to the location of the + * “hidden private memory”. The hidden private can be placed in either GPUVM + * or ATC space. The addresses that fall in the shared aperture are + * re-directed to the on-chip LDS memory hardware. + * + * + * HSA32 Apertures for FLAT_* vector ops + * + * In HSA32 mode, the Private and Shared apertures can be placed anywhere + * in the 32b space except at 0 (Private or Shared Base at zero disables + * the apertures). If the base address of the apertures are non-zero + * (ie apertures exists), the size is always 64KB. + * + * + * GPUVM Apertures for FLAT_* vector ops + * + * In GPUVM mode, the Shared/Private apertures are specified identically + * to HSA64 mode where they are always in the hole at a limited selection + * of locations. + * + * + * Aperture Definitions for SUA and DUA + * + * The interpretation of the aperture register definitions for a given + * VMID is a function of the “SUA Mode” which is one of HSA64, HSA32, or + * GPUVM64 discussed in previous sections.
