Subject: Re: [PATCH v9 2/6] Documentation/kernel-parameters: Add multi-device config_acs example
Date: Thu, 03 Sep 2026 04:06:11 +0000 [thread overview]
Message-ID: <20260903040612.4ADD31F000E9@smtp.kernel.org> (raw)
In-Reply-To: <SI2PR01MB439342D6BDCFD10A2B6207B9DCB62@SI2PR01MB4393.apcprd01.prod.exchangelabs.com>
> The config_acs parameter allows configuring ACS settings for multiple PCI
> devices by separating entries with semicolons. The current documentation
> only illustrates applying one configuration pattern to all devices, but
> does not show how to specify multiple devices with different ACS settings
> in a single parameter. Add an example demonstrating multi-device usage
> with distinct ACS configurations.
>
> Some bootloaders interpret ';' as a command separator, which can cause
> the parameter to be split as multiple commands. Document that the entire
> parameter may need to be quoted to avoid bootloader parsing issues. This
> avoids confusing bootloader errors such as "can't find command <BDF>"
> when passing multiple device entries.
