Subject: [PATCH v7 0/2] net: macb: Wake-on-Lan magic packet GEM and MACB handling
Date: Mon, 20 Jul 2020 10:56:51 +0200 [thread overview]
Message-ID: <cover.1595235208.git.nicolas.ferre@microchip.com> (raw)
From: Nicolas Ferre <nicolas.ferre@microchip.com>
Hi,
Here is the second part of support for WoL magic-packet on the current macb
driver. This one
is addressing the bulk of the feature and is based on current net-next/master.
MACB and GEM code must co-exist and as they don't share exactly the same
register layout, I had to specialize a bit the suspend/resume paths and plug a
specific IRQ handler in order to avoid overloading the "normal" IRQ hot path.
These changes were tested on both sam9x60 which embeds a MACB+FIFO controller
and sama5d2 which has a GEM+packet buffer type of controller.
Best regards,
Nicolas
Changes in v7:
- Release the spinlock before exiting macb_suspend/resume in case of error
changing IRQ handler
Changes in v6:
- rebase on net-next/master now that the "fixes" patches of the series are
merged in both net and net-next.
- GEM addition and MACB update to finish the support of WoL magic-packet on the
two revisions of the controller.
These 2 patches were last posted in v3 series.
