Subject: [PATCH v3 09/19] scsi: pm80xx: Pass gfp_t flags to libsas event notifiers
Date: Mon, 18 Jan 2021 11:09:45 +0100
Message-ID: <20210118100955.1761652-10-a.darwish@linutronix.de> (raw)
In-Reply-To: <20210118100955.1761652-1-a.darwish@linutronix.de>
Use the new libsas event notifiers API, which requires callers to
explicitly pass the gfp_t memory allocation flags.
Call chain analysis, pm8001_hwi.c:
pm8001_interrupt_handler_msix() || pm8001_interrupt_handler_intx() || pm8001_tasklet()
-> PM8001_CHIP_DISP->isr() = pm80xx_chip_isr()
-> process_oq [spin_lock_irqsave(&pm8001_ha->lock, ...)]
-> process_one_iomb()
-> mpi_hw_event()
-> hw_event_sas_phy_up()
-> pm8001_bytes_dmaed()
-> hw_event_sata_phy_up
-> pm8001_bytes_dmaed()
All functions are invoked by process_one_iomb(), which is invoked by the
interrupt service routine and the tasklet handler. A similar call chain
is also found at pm80xx_hwi.c. Pass GFP_ATOMIC.
For pm8001_sas.c, pm8001_phy_control() runs in task context as it calls
wait_for_completion() and msleep(). Pass GFP_KERNEL.
