解锁Nvidia 3000卡上的FP/BF16指令发行率到其专业等效
这个Linux内核模块结合了CMP解锁器的V67/PLM技术与UEFI方法的驱动前时间。 它运行解锁，写出速度选择器(SS0 0x8888888888，它选择了完整的BF16速率，以及4位SS1 0x8 IMLA4)，并在未修改的NVIDIA驱动程序绑定卡之前执行FLR. 它既不是一个UEFI应用程序，也不是一个补丁的NVIDIA驱动程序。
这个早期klod驱动器的好处是，它不需要每次手动补丁nvidia 发布一个新的驱动器版本。
这个解锁的作用是它翻倍，指令发行速度为FP/BF16 FMA在GA102,GA103,GA104和GA106卡上进入FP32操作。

Unlock FP/BF16 instruction issue rate on Nvidia 3000's cards to their professional equivalents
This Linux kernel module combines the CMP unlocker's V67/PLM technique with the pre-driver timing of the UEFI approach. It runs the unlock, writes the speed selectors (SS0 0x88888888, which selects the full BF16 rate, and the 4-bit SS1 0x8 IMLA4) and performs FLR before the unmodified NVIDIA driver binds the card. It is neither a UEFI application nor a patched NVIDIA driver.
The benefit of this early kmod driver is that it does not require manual patching each time nvidia releases a new driver version.
The effect of this unlock is that it doubles the instruction issuing speed of FP/BF16 FMA into FP32 operations on GA102, GA103, GA104 and GA106 cards.
3090 Ti dense 8192³ GEMM at 450 W, five-sample medians with FP32 accumulation:
First run:
git clone https://github.com/Zagitta/gpu-unlock
cd gpu-unlock
make install
Then append gpu_unlock.targets=all to your kernel command line, keeping
existing options:
- GRUB (Debian/Ubuntu/Mint): add it inside GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, then run sudo update-grub.
- GRUB (Arch/CachyOS): same edit, then run
sudo grub-mkconfig -o /boot/grub/grub.cfg.
- Fedora/RHEL: run
sudo grubby --update-kernel=ALL --args="gpu_unlock.targets=all".
- systemd-boot: append it to the options line in your boot entry
(bootctl status shows its location).
- UKI / generated entries: add it to /etc/kernel/cmdline and regenerate
your boot images/entries (e.g. sudo mkinitcpio -P for mkinitcpio UKIs).
Every build downloads the pinned NVIDIA/CachyOS inputs over HTTPS, checks
their SHA-256, and generates firmware only in the build directory and the
binary package. All three formats install through the same make install-*
targets. Packages are built from the committed HEAD.
Build, install build dependencies, and install the packages in one step (asks for your sudo password):
make install # detect the distribution and select an installer
make install-arch # makepkg -sif
make install-deb # apt-get build-dep, dpkg-buildpackage, apt-get install
make install-rpm # dnf builddep, rpmbuild, dnf install
make install uses /etc/os-release (ID, then ID_LIKE) to detect Arch,
Debian/Ubuntu, or Fedora/RHEL/CentOS families. The RPM installer requires DNF.
For other distributions, select a compatible explicit target above.
make arch, make deb and make rpm only build. Debian and RPM packages go
to build/deb and build/rpm. The NVIDIA inputs are cached in
~/.cache/gpu-unlock/inputs (make inputs; override with INPUTS=).
dpkg-buildpackage itself never uses the network, so a clean-chroot build (sbuild or
pbuilder) needs GPU_UNLOCK_INPUTS pointing at that cache.
The make dist archive, the Debian source package and the .nosrc.rpm
contain no NVIDIA archives or generated firmware.
The packages put gpu_unlock and its firmware in the initramfs and load it
there, before nvidia can bind a card:
- mkinitcpio: /etc/mkinitcpio.conf.d/zz-gpu-unlock.conf inserts gpu_unlock right before nvidia in MODULES, so a display card is blank
for as short a time as possible. Without nvidia in the image, it goes
last and still runs before an nvidia loaded from the root filesystem.
Images are rebuilt on install. mkinitcpio ignores drop-ins for an image
built with -c <config> or a preset _config; put gpu_unlock right
before nvidia in that config's MODULES yourself.
- initramfs-tools: /usr/share/initramfs-tools/modules.d/gpu-unlock.conf.
- dracut: /usr/lib/dracut/dracut.conf.d/gpu-unlock.conf.
With initramfs-tools and dracut, the module is built for every installed kernel that has headers, and those kernels' images are rebuilt on install and again on removal. Kernels installed later get the module and a new image from the kernel's own install hooks.
There is no softdep nvidia pre: rule: kmod honours only the first
softdep nvidia line it reads, so other packages' rules (nvidia-utils,
gddr6_hwmon) would silently override it, or it would override theirs.
The module does nothing unless the kernel command line opts in:
gpu_unlock.targets=all # every unbound GA102/GA103/GA104/GA106 card
gpu_unlock.targets=0000:21:00.0 # only these cards
gpu_unlock.targets=0000:21:00.0,0000:22:00.0 # comma-separated
Addresses are full PCI names as lspci -D prints them (hex digits in either
case), independent of GPU numbering and display role. An entry that is not
a GA102/GA103/GA104/GA106 card, including all mixed with addresses, is logged and ignored.
The cards are unlocked concurrently, about a second in all however many
there are, and each on its own: a card that is already bound or powered
down is skipped. Bus mastering that the board firmware left on (Supermicro
X11 does this whatever its option ROM and bus master settings) is cleared
first; a card some driver already initialised is still refused. Then
nvidia loads and binds every card as usual.
The display card works too. Its firmware framebuffer (the boot console and
Plymouth) keeps running while the unlock's firmware steps run, and is
removed just before the card's reset, as nvidia-drm would do a moment
later anyway. Its screen is blank from that reset until nvidia-drm takes
over.
Loading the module by hand after boot does nothing to a card that nvidia
has bound.
Suspend to RAM powers the cards off, which resets the speed selectors. After
resume the module unlocks every card it unlocked at boot again, before
nvidia resumes it: its suspend notifier runs just ahead of the one nvidia
resumes its cards from (NVreg_UseKernelSuspendNotifiers=1, the default in
current drivers; nvidia-resume.service runs later still). This adds about a
second to resume. A card that kept power, as in suspend to idle, is still
unlocked and is only read. A card that nvidia has already resumed, or that is
bound to another driver, is left as it is, and the log says why. Add
gpu_unlock.resume=0 to the kernel command line, or write 0 to
/sys/module/gpu_unlock/parameters/resume, to turn this off. Hibernation is
not covered.
Check the result with:
journalctl -k -b | grep gpu_unlock
lspci -nnk -s 0000:21:00.0
To stop unlocking, remove gpu_unlock.targets= from the kernel command line;
for a one-off boot, delete it in the bootloader's edit screen. Removing the
packages also removes the module and the initramfs drop-ins.
If the firmware on a card never stops, the module logs it and keeps the DMA buffers that firmware may still use until the next power off. Power off before trying again.
The kernel module and local packaging are GPL-2.0-only. The generated payload
derives from the pinned CMP reference; NVIDIA firmware remains under its own
terms. See firmware/NOTICE.md and licenses/ for attribution and notices.
