PERR# Generation
Параметр, включающий/отключающий генерирование PERR# (PCI bus parity error) — сигнал ошибки в четности данных, передаваемых по шине PCI. Сигнал PERR# направляется на контролер немаскируемых прерываний (NMI).
PERR# является устойчивым сигналом трех состояний, используемым для сигнализации об обнаружении ошибки четности, связанной с фазой данных. Во время каждой фазы данных транзакции чтения целевой объект передает данные на шину AD. Таким образом, цель состоит в том, чтобы обеспечить правильную четность для инициатора по сигналу PAR, начинающемуся через один такт после подтверждения TRDY# (Target Ready). По завершении каждой фазы данных инициатор обязан зафиксировать содержимое AD (31: 0] и C/BE # [3: 0] и рассчитать ожидаемый паритет в течение тактового цикла, сразу после завершения фазы данных. Затем инициатор фиксирует бит четности, предоставленный целью, из сигнала PAR на следующем переднем фронте тактовых импульсов и сравнивает вычисленную и фактическую четность. Если происходит несовпадение, инициатор затем устанавливает PERR# в течение следующих тактовых импульсов (если это можно сделать с помощью единицы в бите ответа об ошибке четности в его регистре команд.) Утверждение PERR # откладывает завершение каждой фазы данных на два тактовых цикла PCI.
Иными словами, включение данной функции позволяет обнаруживать ошибки, возникающие при передаче данных по шине PCI.
Возможные варианты значений:
Disable — генерирование PERR# отключено
Enable — генерирование PERR# включено

Perr generation что это
I recently bought a JGINYUE X99-D8 to use with my home lab. However before I bought it I couldn’t find much info about it, such as if it it supported SR-IOV or even virtualisation at all. Here’s all the BIOS options that shipped with my motherboard.
BIOS Dump using flashrom; flashrom shows this chipset as untested, this rom might brick your motherboard.
I’ve also made a custom lm-sensors config file for this motherboard.
All of this article is my own findings but Miyconst’s video is worth checking out.
Important Features & Notes
AER Errors
If you experience AER errors in Linux, they can be avoided by disabling PCI-E ASPM, you will need to disable it globally and then go through each IIO Socket setting PCI-E ASPM to Disabled. This is common with other X99 motherboards.
Virtualisation
- SR-IOV
- VT-x
- VT-d
- ACS
- ARI Forwarding
Networking
- 2 × RTL8111/8168/8411 PCI Express Gigabit Ethernet Controllers
- Capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation
- Supports Wake-on: pumbg (PHY, Unicast, Multicast, Broadcast, Magic Packet)
PCIe Slots
- PCIe 2.0 x1 — Chipset
- PCIe 3.0 x4 (M.2 M Key) — CPU0
- PCIe 3.0 x16 — CPU0
- PCIe 2.0 x1 — Chipset
- PCIe 3.0 x4 (M.2 M Key) — CPU1
- PCIe 3.0 x16 — CPU1
- PCIe 3.0 x8 (Physically x16) — CPU0
The PCIe x1 slots can easily be cut open using small side cutters to fit a card bigger than x1, but using a bigger card will obstruct an M.2 SSD.
Miscellaneous
- SATA 3.0, using SATA & sSATA Controllers
- 8 Channel RAM (2 CPUs × 4 Channels)
- PCIe Bifurcation Settings
- ECC & Non-ECC RAM Supported
