[Linux-stable-mirror] [PATCH] rpmsg: virtio_rpmsg_bus: fix rpmsg_probe() for virtio-mmio transport

by Anup Patel

When virtio-rpmsg device is provided via virtio-mmio transport, the dma_alloc_coherent() (called by rpmsg_probe()) fails on ARM/ARM64 systems because "vdev->dev.parent->parent" device is used as parameter to dma_alloc_coherent(). The "vdev->dev.parent->parent" device represents underlying remoteproc platform device when virtio-rpmsg device is provided via virtio-remoteproc transport. When virtio-rpmsg device is provided via virtio-mmio transport, the "vdev->dev.parent->parent" device represents the parent device of virtio-mmio platform device and dma_alloc_coherent() fails for this device because generally there is no corresponding platform device and dma_ops are not setup for "vdev->dev.parent->parent". This patch fixes dma_alloc_coherent() usage in rpmsg_probe() by trying dma_alloc_coherent() with "vdev->dev.parent" device when it fails with "vdev->dev.parent->parent" device.

[Linux-stable-mirror] [PATCH 1/3] x86/tsc: Future-proof native_calibrate_tsc()

by Len Brown

From: Len Brown <len.brown(a)intel.com> If native_calibrate_tsc() can not discover the TSC frequency, via CPUID or via built-in table, it must return without setting X86_FEATURE_TSC_KNOWN_FREQ. Otherwise, X86_FEATURE_TSC_KNOWN_FREQ will prevent TSC refined calibration. This patch allows Linux to correctly support future Intel hardware, that has (cpu_khz != tsc_khz), and support for CPUID.15 without support for CPUID.15.crystal_khz. This patch is needed since X86_FEATURE_TSC_KNOWN_FREQ was added in Linux-4.10: commit 4ca4df0b7eb0 ("x86/tsc: Mark TSC frequency determined by CPUID as known") If not applied, such systems will run with tsc_khz = cpu_khz, which may result in under-stated TSC rate, and time-of-day drift.

[Linux-stable-mirror] [PATCH] drm/i915: Apply Display WA #1183 on skl, kbl, and cfl

by Lucas De Marchi

Display WA #1183 was recently added to workaround "Failures when enabling DPLL0 with eDP link rate 2.16 or 4.32 GHz and CD clock frequency 308.57 or 617.14 MHz (CDCLK_CTL CD Frequency Select 10b or 11b) used in this enabling or in previous enabling." This workaround was designed to minimize the impact only to save the bad case with that link rates. But HW engineers indicated that it should be safe to apply broadly, although they were expecting the DPLL0 link rate to be unchanged on runtime. We need to cover 2 cases: when we are in fact enabling DPLL0 and when we are just changing the frequency with small differences. This is based on previous patch by Rodrigo Vivi with suggestions from Ville Syrjälä.

[Linux-stable-mirror] Patch "tcp_bbr: reset long-term bandwidth sampling on loss recovery undo" has been added to the 4.9-stable tree

Fix BBR so that upon notification of a loss recovery undo BBR resets long-term bandwidth sampling. Under high reordering, reordering events can be interpreted as loss. If the reordering and spurious loss estimates are high enough, this can cause BBR to spuriously estimate that we are seeing loss rates high enough to trigger long-term bandwidth estimation. To avoid that problem, this commit resets long-term bandwidth sampling on loss recovery undo events.
