Most DPAA1 devices do not support a soft reset which is an issue if Kexec starts a new kernel. This patch series allows Kexec to function by detecting that the QBMan device was previously initialized.
The patches fix some issues with device cleanup as well as ensuring that the location of the QBMan private memories has not changed after the execution of the Kexec. Changes since v1: - Removed a bug fix and sent it separately to ease backporting Roy Pledge (7): soc/fsl/qbman: Rework QBMan private memory setup soc/fsl/qbman: Cleanup buffer pools if BMan was initialized prior to bootup soc/fsl/qbman: Cleanup QMan queues if device was already initialized soc/fsl/qbman: Fix drain_mr_fqni() soc/fsl/qbman: Disable interrupts during portal recovery soc/fsl/qbman: Fixup qman_shutdown_fq() soc/fsl/qbman: Update device tree with reserved memory drivers/soc/fsl/qbman/bman.c | 17 ++++---- drivers/soc/fsl/qbman/bman_ccsr.c | 36 +++++++++++++++- drivers/soc/fsl/qbman/bman_portal.c | 18 +++++++- drivers/soc/fsl/qbman/bman_priv.h | 5 +++ drivers/soc/fsl/qbman/dpaa_sys.c | 63 ++++++++++++++++------------ drivers/soc/fsl/qbman/qman.c | 83 +++++++++++++++++++++++++++++-------- drivers/soc/fsl/qbman/qman_ccsr.c | 59 +++++++++++++++++++++++--- drivers/soc/fsl/qbman/qman_portal.c | 18 +++++++- drivers/soc/fsl/qbman/qman_priv.h | 8 ++++ 9 files changed, 246 insertions(+), 61 deletions(-) -- 2.7.4
