[PATCH] serial: imx: fix overrun interrupts in DMA mode

by Johan Hovold

Commit 76821e222c18 ("serial: imx: ensure that RX irqs are off if RX is off") accidentally enabled overrun interrupts unconditionally when deferring DMA enable until after the receiver has been enabled during startup. Fix this by using the DMA-initialised instead of DMA-enabled flag to determine whether overrun interrupts should be enabled. Note that overrun interrupts are already accounted for in imx_uart_clear_rx_errors() when using DMA since commit 41d98b5da92f ("serial: imx-serial - update RX error counters when DMA is used").

Donenfeld" <Jason(a)zx2c4.com> Date: Mon, 21 Mar 2022 18:48:05 -0600 Subject: [PATCH] random: skip fast_init if hwrng provides large chunk of entropy At boot time, EFI calls add_bootloader_randomness(), which in turn calls add_hwgenerator_randomness(). Currently add_hwgenerator_randomness() feeds the first 64 bytes of randomness to the "fast init" non-crypto-grade phase. But if add_hwgenerator_randomness() gets called with more than POOL_MIN_BITS of entropy, there's no point in passing it off to the "fast init" stage, since that's enough entropy to bootstrap the real RNG. The "fast init" stage is just there to provide _something_ in the case where we don't have enough entropy to properly bootstrap the RNG. But if we do have enough entropy to bootstrap the RNG, the current logic doesn't serve a purpose. So, in the case where we're passed greater than or equal to POOL_MIN_BITS of entropy, this commit makes us skip the "fast init" phase.
