dde_ipxe: update Intel NIC support list from upstream Also, the repository URL was adapted to the permanent redirect to github to prevent the following warning. dde_ipxe download http://git.ipxe.org/ipxe.git dde_ipxe git Cloning into 'src/lib/dde_ipxe'... dde_ipxe git warning: redirecting to https://github.com/ipxe/ipxe/ dde_ipxe update src/lib/dde_ipxe 2022-03-18 13:03:21 +00:00			`URL(ipxe) := https://github.com/ipxe/ipxe.git`

dde_ipxe: add Intel I217-LM PCI ID Fixes #1220. 2014-08-01 15:16:38 +00:00			`PATCHES := patches/dde_ipxe.patch \`
dde_ipxe: skip MAC/PHY reset on Intel NICs Inspired by the mailing-list posting [1], this commit removes the MAC/PHY reset for all Intel cards and effectively prevents the bandwidth drop to 10 MBit/s (e.g., on i217lm). I understand it as preliminary fix for practical reasons - a real fix would be to update the ipxe port and monitor for more postings like the one mentioned.

dde_ipxe: update Intel NIC driver to latest upstream This patch is motivated by sporadic hangs during link down/up on i219 NICs handling and the fix implemented upstream in https://git.ipxe.org/ipxe.git/commit/546dd51de8459d4d09958891f426fa2c73ff090d Issue #1220 2019-05-02 13:18:12 +00:00			`patches/intel_update.patch \`
dde_ipxe: improve throughput for Realtek devices By increasing the ring descriptor count the throughput increased from few kB/s to the range of MB/s. Issue #3939 2021-02-04 18:02:35 +00:00			`patches/tg3.patch \`
nic/ipxe: batch TX requests A bunch of transmit requests received by the Uplink server (nic_router) are currently added one by one to the ring buffer and every time the hardware is notified to process each single request. Instead, add as many as possible transmit requests in the ring buffer of the hardware and when done trigger the hardware to process the ring. Additionally, don't receive an "processed" TX IRQ for each element in the ring, which causes high CPU load. With this commit the TX IRQs in the ipxe driver for a iperf -c X.X.X.X -t 60 from within a VM to the outside iperf server is reduced from about ~2'600'000 IRQs to about ~200'000. The overall CPU load for the driver (when executed alone on CPU 0) is reduced from ~85 percent load to ~45 percent load. Issue #5149 2024-02-07 08:09:38 +00:00			`patches/realtek.patch \`
nic/ipxe: add throttle RX interrupt support The commit adds support to throttle the rate of the RX IRQs to a specified value. The effect is, that no RX IRQs below the time threshold will fire and therefore the CPU load gets reduced on the host. Trade-off gaming between cpu load, throughput, overload. Modular Sculpt 23.10 on S938 as testcase. In brackets the CPU affinity is denoted. ipxe (0,0) -> nic_router (1,0) -> Debian VM vbox6 (3,0) and (3,1) VM: iperf -C X.X.X.X -t 60 -R iperf server X.X.X.X is outside Sculpt and sends data due to '-R' to VM Non representative measure points: cpu load - ipxe - nic_router - iperf throughput -------------------------------------------------- w/o patch - ~80% - ~50% - ~706 MBit/s - 0 -> throttling off by default on S938 patch 651 - ~20% - ~35% - ~763 MBit/s - 651 -> 0.166ms throttle RX IRQ patch 5580 - ~15% - ~25% - ~650 MBit/s - 5580 -> 1.4ms throttle RX IRQ Issue #5149 2024-02-07 13:44:37 +00:00			`patches/intel_tx_batch.patch \`
