[PATCH 5/6] staging: fsl-dpaa2/eth: Compute needed headroom per frame

For non-linear skbs we build scatter-gather frames and allocate a new buffer for the S/G table in which we reserve the required headroom, so the actual skb headroom size doesn't matter. Rather than use a one-size-fits-all approach, decide when to enforce headroom requirements on a frame by frame

[PATCH 0/6] staging: fsl-dpaa2/eth: Frame buffer optimizations

This patchset continues the work related to frame buffer layout. The first two patches fix an issue and simplify some rather convoluted formulas introduced by a previous commit. The third adds a new counter for TX skb reallocations due to insufficient headroom. This helped us notice that most of

[PATCH 1/6] staging: fsl-dpaa2/eth: Fix access to FAS field

Commit 4b2d9fe87950 ("staging: fsl-dpaa2/eth: Extra headroom in RX buffers") removes the software annotation (SWA) area from the RX buffer layout, as it's not used by anyone, but fails to update the macros for accessing hardware annotation (HWA) fields, which is right after the SWA in the buffer

[PATCH 4/6] staging: fsl-dpaa2/eth: Don't enable FAS on Tx

For Tx confirmed frames that have an error indication in the frame descriptor, we look at the Frame Annotation Status field (in the buffer headroom) for details on the root cause and then print a debug message with that information. While useful in initial development stages, it doesn't bring

Commit 4b2d9fe87950 ("staging: fsl-dpaa2/eth: Extra headroom in RX buffers") tried to avoid the performance penalty of doing skb reallocations in the network stack for IP forwarded frames between two DPAA2 Ethernet interfaces. This led to a (too) complicated formula that relies on the stack's

[PATCH 6/6] staging: fsl-dpaa2/eth: Make Tx buffer alignment optional

[RFC] irqchip: add support for LS1021A external interrupt lines

The LS1021A allows inverting the polarity of six interrupt lines IRQ[0:5] via the scfg_intpcr register, effectively allowing IRQ_TYPE_LEVEL_LOW and IRQ_TYPE_EDGE_FALLING for those. We just need to check the type, set the relevant bit in INTPCR accordingly, and fixup the type argument before

[PATCH] sched/autogroup: move sched.h include

Move local "sched.h" include to the bottom. sched.h defines several macros that are getting redefined in ARCH-specific code, for instance, finish_arch_post_lock_switch() and prepare_arch_switch(), so we need ARCH-specific definitions to come in first. Suggested-by: Martin Schwidefsky

[PATCH v4 12/12] cpufreq: dt: Reintroduce independent_clocks platform data

The Platform data was removed earlier by, 'commit eb96924acddc ("cpufreq: dt: Kill platform-data")' since there were no users at that time. Now this is required when the each of the cpu clocks can be scaled independently, which is the case for krait cores. So reintroduce it. Signed-off-by:
