It is configurable to any workload but the default -ck patch is aimed at the desktop and -cks is available with more emphasis on serverspace. I have used SD for the first time with this patchset, and I have to say, my experience has been very positive over the past four days. My desktop has been extraordinarily smooth during interactive tasks with no audio drop-outs. Best of all, the desktop has been completely responsive despite CPU hogging tasks. I do not need to nice X either. This looks like a perfect scheduler. Swap prefetch continues to work its miracles as I've been doing a lot of work lately with a 33"x44" poster that contains many high-resolutions images, while using gimp at the same time! Thanks so much for all your incredible work! 乾杯 best, Ryan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

[PATCH] net: bcmgenet: use ethtool_op_get_ts_info()
This change enables the use of SW timestamping on the Raspberry Pi 4.
bcmgenet's transmit function bcmgenet_xmit() implements software
timestamping. However the SOF_TIMESTAMPING_TX_SOFTWARE capability was
missing and only SOF_TIMESTAMPING_RX_SOFTWARE was announced. By using
ethtool_ops bcmgenet_ethtool_ops() as get_ts_info(), the
SOF_TIMESTAMPING_TX_SOFTWARE capability is announced.
Similar to commit a8f5cb9e7991 ("smsc95xx: use ethtool_op_get_ts_info()")
