-# NVIDIA Linux Open GPU Kernel Module Source
-
-This is the source release of the NVIDIA Linux open GPU kernel modules,
-version 550.78.
-
-
-## How to Build
-
-To build:
-
- make modules -j$(nproc)
-
-To install, first uninstall any existing NVIDIA kernel modules. Then,
-as root:
-
- make modules_install -j$(nproc)
-
-Note that the kernel modules built here must be used with GSP
-firmware and user-space NVIDIA GPU driver components from a corresponding
-550.78 driver release. This can be achieved by installing
-the NVIDIA GPU driver from the .run file using the `--no-kernel-modules`
-option. E.g.,
-
- sh ./NVIDIA-Linux-[...].run --no-kernel-modules
-
-
-## Supported Target CPU Architectures
-
-Currently, the kernel modules can be built for x86_64 or aarch64.
-If cross-compiling, set these variables on the make command line:
-
- TARGET_ARCH=aarch64|x86_64
- CC
- LD
- AR
- CXX
- OBJCOPY
-
-E.g.,
-
- # compile on x86_64 for aarch64
- make modules -j$(nproc) \
- TARGET_ARCH=aarch64 \
- CC=aarch64-linux-gnu-gcc \
- LD=aarch64-linux-gnu-ld \
- AR=aarch64-linux-gnu-ar \
- CXX=aarch64-linux-gnu-g++ \
- OBJCOPY=aarch64-linux-gnu-objcopy
-
-
-## Other Build Knobs
-
-NV_VERBOSE - Set this to "1" to print each complete command executed;
- otherwise, a succinct "CC" line is printed.
-
-DEBUG - Set this to "1" to build the kernel modules as debug. By default, the
- build compiles without debugging information. This also enables
- various debug log messages in the kernel modules.
-
-These variables can be set on the make command line. E.g.,
-
- make modules -j$(nproc) NV_VERBOSE=1
-
-
-## Supported Toolchains
-
-Any reasonably modern version of GCC or Clang can be used to build the
-kernel modules. Note that the kernel interface layers of the kernel
-modules must be built with the toolchain that was used to build the
-kernel.
-
-
-## Supported Linux Kernel Versions
-
-The NVIDIA open kernel modules support the same range of Linux kernel
-versions that are supported with the proprietary NVIDIA kernel modules.
-This is currently Linux kernel 3.10 or newer.
-
-
-## How to Contribute
-
-Contributions can be made by creating a pull request on
-https://github.com/NVIDIA/open-gpu-kernel-modules
-We'll respond via GitHub.
-
-Note that when submitting a pull request, you will be prompted to accept
-a Contributor License Agreement.
-
-This code base is shared with NVIDIA's proprietary drivers, and various
-processing is performed on the shared code to produce the source code that is
-published here. This has several implications for the foreseeable future:
-
-* The GitHub repository will function mostly as a snapshot of each driver
- release.
-
-* We do not expect to be able to provide revision history for individual
- changes that were made to NVIDIA's shared code base. There will likely
- only be one git commit per driver release.
-
-* We may not be able to reflect individual contributions as separate
- git commits in the GitHub repository.
-
-* Because the code undergoes various processing prior to publishing here,
- contributions made here require manual merging to be applied to the shared
- code base. Therefore, large refactoring changes made here may be difficult to
- merge and accept back into the shared code base. If you have large
- refactoring to suggest, please contact us in advance, so we can coordinate.
-
-
-## How to Report Issues
-
-Problems specific to the Open GPU Kernel Modules can be reported in the
-Issues section of the https://github.com/NVIDIA/open-gpu-kernel-modules
-repository.
-
-Further, any of the existing bug reporting venues can be used to communicate
-problems to NVIDIA, such as our forum:
-
-https://forums.developer.nvidia.com/c/gpu-graphics/linux/148
-
-or linux-bugs@nvidia.com.
-
-Please see the 'NVIDIA Contact Info and Additional Resources' section
-of the NVIDIA GPU Driver README for details.
-
-Please see the separate [SECURITY.md](SECURITY.md) document if you
-believe you have discovered a security vulnerability in this software.
-
-
-## Kernel Interface and OS-Agnostic Components of Kernel Modules
-
-Most of NVIDIA's kernel modules are split into two components:
-
-* An "OS-agnostic" component: this is the component of each kernel module
- that is independent of operating system.
-
-* A "kernel interface layer": this is the component of each kernel module
- that is specific to the Linux kernel version and configuration.
-
-When packaged in the NVIDIA .run installation package, the OS-agnostic
-component is provided as a binary: it is large and time-consuming to
-compile, so pre-built versions are provided so that the user does
-not have to compile it during every driver installation. For the
-nvidia.ko kernel module, this component is named "nv-kernel.o_binary".
-For the nvidia-modeset.ko kernel module, this component is named
-"nv-modeset-kernel.o_binary". Neither nvidia-drm.ko nor nvidia-uvm.ko
-have OS-agnostic components.
-
-The kernel interface layer component for each kernel module must be built
-for the target kernel.
-
-
-## Directory Structure Layout
-
-- `kernel-open/` The kernel interface layer
-- `kernel-open/nvidia/` The kernel interface layer for nvidia.ko
-- `kernel-open/nvidia-drm/` The kernel interface layer for nvidia-drm.ko
-- `kernel-open/nvidia-modeset/` The kernel interface layer for nvidia-modeset.ko
-- `kernel-open/nvidia-uvm/` The kernel interface layer for nvidia-uvm.ko
-
-- `src/` The OS-agnostic code
-- `src/nvidia/` The OS-agnostic code for nvidia.ko
-- `src/nvidia-modeset/` The OS-agnostic code for nvidia-modeset.ko
-- `src/common/` Utility code used by one or more of nvidia.ko and nvidia-modeset.ko
-- `nouveau/` Tools for integration with the Nouveau device driver
-
-
-## Nouveau device driver integration
-
-The Python script in the 'nouveau' directory is used to extract some of the
-firmware binary images (and related data) encoded in the source code and
-store them as distinct files. These files are used by the Nouveau device
-driver to load and communicate with the GSP firmware.
-
-The layout of the binary files is described in nouveau_firmware_layout.ods,
-which is an OpenDocument Spreadsheet file, compatible with most spreadsheet
-software applications.
-
-
-## Compatible GPUs
-
-The NVIDIA open kernel modules can be used on any Turing or later GPU
-(see the table below). However, in the __DRIVER_VERION__ release, GeForce and
-Workstation support is considered to be Beta quality. The open kernel modules
-are suitable for broad usage, and NVIDIA requests feedback on any issues
-encountered specific to them.
-
-For details on feature support and limitations, see the NVIDIA GPU driver
-end user README here:
-
-https://us.download.nvidia.com/XFree86/Linux-x86_64/550.78/README/kernel_open.html
-
-For vGPU support, please refer to the README.vgpu packaged in the vGPU Host
-Package for more details.

+# NVIDIA Linux Open GPU with P2P support
+
+This is a fork of NVIDIA's driver with P2P support added for 4090's.
+
+`./install.sh` to install if that's all you want.
+
+You may need to uninstall the driver from DKMS. Your system needs large BAR support and IOMMU off.
+
+Not sure all the cache flushes are right, please file issues on here if you find any issues.
+
+NOTE: This is not a hack, this is using PCIe according to the spec. With cleanups, this could potentially be upstreamed.
+
+## How it works
+
+Normally, P2P on NVIDIA cards uses MAILBOXP2P. This is some hardware interface designed to allow GPUs to transfer memory back in the days of small BAR. It is not present or disabled in hardware on the 4090s, and that's why P2P doesn't work. There [was a bug in early versions](https://forums.developer.nvidia.com/t/standard-nvidia-cuda-tests-fail-with-dual-rtx-4090-linux-box/233202) of the driver that reported that it did work, and it was actually sending stuff on the PCIe bus. However, because the mailbox hardware wasn't present, these copies wouldn't go to the right place. You could even crash the system by doing something like `torch.zeros(10000,10000).cuda().to("cuda:1")`
+
+In some 3090s and all 4090s, NVIDIA added large BAR support.
+
+```

+```
+
+Notice how BAR1 is size 32G. In H100, they also added support for a PCIe mode that uses the BAR directly instead of the mailboxes, called BAR1P2P. So, what happens if we try to enable that on a 4090?
+
+We do this by bypassing the HAL and calling a bunch of the GH100 methods directly. Methods like `kbusEnableStaticBar1Mapping_GH100`, which maps the entire VRAM into BAR1. This mostly just works, but we had to disable the use of that region in the `MapAperture` function for some reason. Shouldn't matter.
+
+```
+[ 3491.654009] NVRM: kbusEnableStaticBar1Mapping_GH100: Static bar1 mapped offset 0x0 size 0x5e9200000
+[ 3491.793389] NVRM: kbusEnableStaticBar1Mapping_GH100: Static bar1 mapped offset 0x0 size 0x5e9200000
+```
+
+Perfect, we now have the VRAM mapped. However, it's not that easy to get P2P. When you run `./simpleP2P` from `cuda-samples`, you get this error.
+
+```

+```
+
+Failing with an MMU fault. So you dive into this and find that it's using `GMMU_APERTURE_PEER` as the mapping type. That doesn't seem supported in the 4090. So let's see what types are supported, `GMMU_APERTURE_VIDEO`,`GMMU_APERTURE_SYS_NONCOH`, and `GMMU_APERTURE_SYS_COH`. We don't care about being coherent with the CPU's L2 cache, but it does have to go out the PCIe bus, so we rewrite `GMMU_APERTURE_PEER` to `GMMU_APERTURE_SYS_NONCOH`. We also no longer set the peer id that was corrupting the page table.
+
+```
+cudaMemcpyPeer / cudaMemcpy between GPU0 and GPU1: 24.21GB/s
+Preparing host buffer and memcpy to GPU0...
+Run kernel on GPU1, taking source data from GPU0 and writing to GPU1...

+Verification error @ element 2: val = 0.000000, ref = 8.000000
+```
+
+Progress! `./simpleP2P` appears to work, however the copy isn't happening. The address is likely wrong. It turns out they have a separate field for the peer address called `fldAddrPeer`, we change that to `fldAddrSysmem`. We also print out the addresses and note that the physical BAR address isn't being added properly, they provide a field `fabricBaseAddress` for `GMMU_APERTURE_PEER`, we reuse it and put the `BAR1` base address in there.
+
+That's it. Thanks to NVIDIA for writing such a stable driver. And with this, the tinybox green is even better.
