Subject: [PATCH v2 0/7] Rework device probing
Date: Thu, 26 Mar 2026 11:24:16 +0100 [thread overview]
Message-ID: <20260326102424.2361945-1-david.marchand@redhat.com> (raw)
In-Reply-To: <20260323105306.1531689-1-david.marchand@redhat.com>
Applications relying on device hotplug don't work well with the default
probing of all available resources.
This series proposes to change this behavior via a new EAL option.

David Marchand
Changes since v1:
- restored per bus scan mode,
- fixed logic in device selection for dma/idxd,
- fixed raw/ifpga hotplug on ifpga bus,
- fixed some doxygen,
Changes since RFC v3:
- removed per bus scan mode,
Changes since RFC v2:
- went one step further and reworked devargs lookup in buses following
Bruce comment (see patch 4 which is cosmetic, and patch 5),
- updated device selection helper accordingly and
changed API to be device name based,
- renamed option, added check on -b presence, updated doc in the last
patch,
Changes since RFC v1:
- reviewed bus probe() and cleaned up NXP drivers,
- changed approach following Bruce comment,
David Marchand (7):
devtools: check packet forwarding in null test
bus/fslmc: fix bus cleanup
drivers/bus: require probe function for NXP drivers
drivers: cleanup devargs lookup in bus scan
bus: factorize devargs lookup
bus: factorize device selection
eal: configure initial device probing
