Subject: [PATCH 00/10] q800: migration fixes
Date: Mon, 28 Feb 2022 22:25:17 +0000 [thread overview]
Message-ID: <20220228222527.8234-1-mark.cave-ayland@ilande.co.uk> (raw)
This patchset contains fixes for the macfb and esp devices which enable
migration of the q800 machine to succeed here in local testing.
Patches 1-5 contain fixes and improvements for migrating the macfb device
whilst patches 6-9 change the ESPState pdma_cb field from being a
function pointer to an integer index that can be included in the migration
stream.
Finally patch 10 ensures that any in-flight SCSI requests active during
migration are resumed correctly post-migration. This is required because
PDMA requires the guest to read/write DMA data and hence an active
SCSI request cannot run to completion before migration starts.
NOTE: this patchset is based upon my previous mos6522 patchset posted at
https://lists.gnu.org/archive/html/qemu-devel/2022-02/msg05248.html.

Mark Cave-Ayland (10):
macfb: add VMStateDescription for MacfbNubusState and MacfbSysBusState
macfb: don't use special irq_state and irq_mask variables in
MacfbState
macfb: increase number of registers saved in MacfbState
macfb: add VMStateDescription fields for display type and VBL timer
macfb: set initial value of mode control registers in
macfb_common_realize()
esp: introduce esp_set_pdma_cb() function
