[PATCH v3 00/39] qdev: Rework how we plug into the parent bus |
Date: |
Tue, 9 Jun 2020 18:38:53 +0200 |
Paolo recently suggested "to move the bus argument (and thus
qdev_set_parent_bus) to qdev_init"[1], and that it "would be quite
large but hopefully scriptable"[2]. Nerd sniped!
The series is big, but at least the bigger patches are all mechanical.
It is based on my "[PATCH v3 00/24] Fixes around device realization".
I'm abstaining from cc'ing maintainers on mechanical conversions. I
still cc: for patches I deem interesting, with related patches thrown
in for context. Let me know if you think I should cc: more widely.
PATCH 01-03 Preliminary cleanup
PATCH 04 New qdev infrastructure
Commit message explains why the current state is
problematic, and how my work improves it.
PATCH 05-12 Convert direct users of qdev
PATCH 13-17 Convert PCI
PATCH 18-21 Convert ISA
PATCH 22-25 Convert SSI
PATCH 26-29 Convert USB
PATCH 30 Garbage collection
PATCH 31-34 Convert aux-bus
PATCH 35-42 Clean up around child device initialization
PATCH 43-52 Convert sysbus
PATCH 53 Stop pretending recursive realization is about to become
real
PATCH 54-56 Convert bus-less devices
PATCH 57 Garbage collection
PATCH 58 Maintain MAINTAINERS
Enjoy!
v3:
* Rebased; noteworthy conflicts
- PATCH 36+48+56: commit fe0fe4735e7 (new machine opentitan)
- PATCH 47: commit 26cd0362dd4 (machines spike_v1.9.1 and
spike_v1.10 are gone)
- PATCH 48: commit 60bf734e64 and 3d46938bbb (new bmc2835
children)
- PATCH 48: v3 of "macio: Fix to realize "mos6522-cuda" and
"mos6522-pmu" devices"
Puh!
* PATCH 08: Coccinelle script in commit message fixed; patch unchanged
* PATCH 19: Two coding style fixes
v2:
* Rebased
* PATCH 02+03:
Old PATCH 02 is actually a revert, replace by propert reverts
[Philippe]
* PATCH 04:
- Fix pasto [Alistair]
- Rephrase qdev_realize_and_unref()'s contract [Paolo]
- qdev_realize() passes on realize error unprefixed (because
prefixes can pile up)
* PATCH 08:
Drop unwanted code motion [Paolo]
* PATCH 09:
- Make the Coccinelle script safer; output unchanged [Paolo]
- Delete a Coccinelle rule that due to rebase applies just once;
move its code changes (hw/char/serial.c, hw/display/ati.c,
half of hw/display/sm501.c) to the next patch
- Move changes to hw/arm/highbank.c to next patch, where they belong
* PATCH 31:
New [Philippe]
* PATCH 32:
Rename aux_realize_bus() to aux_bus_realize() [Philippe]
* PATCH 47:
&dev->parent_obj doesn't work after rebase, use SYS_BUS_DEVICE(dev)
instead
* PATCH 52:
New [Philippe]
* PATCH 53:
Clean up on realize error [David]
* PATCH 54:
Don't restrict qdev_realize_and_unref() to non-null bus [Paolo]
