Subject: [PATCH RFC 00/31] SDHCI and SDIO IRQ improvements
Date: Tue, 18 Feb 2014 15:08:01 +0000 [thread overview]
Message-ID: <20140218150801.GD21483@n2100.arm.linux.org.uk> (raw)
The following patch series is targetted at two things - fixing the SDIO
interrupt handling, and fixing problems with the sdhci driver.
- the first two patches from Thomas Gleixner provide genirq support to
allow us to fix the SDIO interrupt handling in a graceful manner.
- patch 3 adds support for avoiding the buggy sdio_irq thread - the
problem is described in that commit. Other solutions were explored,
but this is the one which was settled on after discussions between
Thomas, scheduler people and myself.
- patches 4 to 7 update sdhci to use a genirq to deal with the threaded
part of the interrupts.
- patch 8 allows card interrupts to be received from a SDIO card while
runtime suspended. Without this patch, Wifi cards attached to a
kernel with runtime PM support built in totally fail to work. This
allows them to work. Tested in 4-bit mode.
- patches 9 onwards are cleanups and fixes to the sdhci code.
