Re: net: macb: fail when there's no PHY

Hello Grant, sorry if I just hijack your conversation, but I'm curious, because we are using the same SoC. Adding linux-arm-kernel to Cc for the general performance issues and linux-mtd for the ECC questions. O:-) Am Donnerstag, 3. Dezember 2020, 23:20:38 CET schrieb Grant Edwards: > On 2020-1

Re: [PATCH] net: macb: remove redundant assignment to variable work_done

of 4.14-rc7 and tested it on an at91sam9g20 based platform. Tested-by: Alexander Dahl Greets Alex

[RFC 3/3] net: macb: Use sram for rx buffers

which are also usable for DMA but directly connected through the AHB without the path through the EBI. This way there are no lost ethernet frames anymore. (If there's too much load however packets can still be dropped by the kernel.) Signed-off-by: Alexander Dahl --- drivers/net/ethernet/cade

[RFC 1/3] net: macb: Add register descriptions

Analog to the already present long register names for GEM, add those for MACB. Taken from the AT91SAM9G20 complete datasheet. Signed-off-by: Alexander Dahl --- drivers/net/ethernet/cadence/macb.h | 66 ++--- 1 file changed, 33 insertions(+), 33 deletions(-) diff

[RFC 2/3] net: macb: Add buffer descriptor names

[RFC 0/3] net: macb: Use SRAM on SoC for RX rings and buffers

Hei hei, this is a small patch series for a problem we encoutered with a board based on an AT91SAM9G20 SoC. I talked about it a few days ago on the #armlinux IRC channel with Alexandre Belloni and Florian Fainelli. The current state of those patches is 'prove of concept', but if this is useful for
