Kernel for Galaxy S24, rebased on CLO sources (WIP)
2dc0b46b5e
During hotplug, it is possible for 6Gbps link speed to be limited all the way down to 1.5 Gbps which may lead to a slower link speed when drive is re-connected. This behavior has been seen on a Intel Lewisburg SATA controller (8086:a1d2) with HGST HUH728080ALE600 drive where SATA link speed was limited to 1.5 Gbps and when re-connected the link came up 3.0 Gbps. This patch was retested on above configuration and showed the hotplugged link to come back online at max speed (6Gbps). I did not see the downgrade when testing on Intel C600/X79, but retested patched linux-4.14-rc5 kernel and didn't see any side effects from this change. Also, successfully retested hotplug on port multiplier 3Gbps link. tj: Minor comment updates. Signed-off-by: David Milburn <dmilburn@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
