Messages in this thread Patch in this message |  | | From | Gustavo Pimentel <> | Subject | [PATCH v2 6/9] PCI: dwc: Define maximum number of vectors | Date | Mon, 9 Apr 2018 10:41:15 +0100 |
| |
Adds a callback that defines the maximum number of vectors that can be use by the Root Complex.
Since this is a parameter associated to each SoC IP setting, makes sense to be configurable and easily visible to future modifications.
The designware IP supports a maximum of 256 vectors.
