2020-05-22firmware: tegra: Defer BPMP probe if shared memory not availableJon Hunter1-2/+2
Since commit 93d2e4322aa7 ("of: platform: Batch fwnode parsing when adding all top level devices") was added, the probing of the Tegra SRAM device has occurred later in the boot sequence, after the BPMP has been probed. The BPMP uses sections of the SRAM for shared memory and if the BPMP is probed before the SRAM then it fails to probe and never tries again. This is causing a boot failure on Tegra186 and Tegra194. Fix this by allowing the probe of the BPMP to be deferred if the SRAM is not available yet. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>

Add support for the Meson GX SoCs to the meson-ee-pwrc driver. The power domains on the GX SoCs are very similar to G12A. The only known differences so far are: - The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the VPU power-domain) - The GX SoCs have an additional reset line called "dvin" Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Link: https://lore.kernel.org/r/20200515204709.1505498-5-martin.blumenstingl@googlemail.com
2020-05-20soc: amlogic: meson-ee-pwrc: add support for Meson8/Meson8b/Meson8m2Martin Blumenstingl1-9/+77
This adds support for the power domains on Meson8/Meson8b/Meson8m2. Meson8 doesn't use any reset lines while Meson8b and Meson8m2 use the same set of reset lines (which is different from the newer SoCs). Add dedicated compatible strings for Meson8, Meson8b and Meson8m2 to support these differences. Notable differences between Meson8 and G12A are: - there is no HHI_VPU_MEM_PD_REG2 on the 32-bit SoCs - the Meson8b datasheet describes an "audio DSP memory" power domain which is used for the hardware audio decoder - the "amlogic,ao-sysctrl" only includes the power management related registers on the 32-bit SoCs, meaning the for example the AO_RTI_GEN_PWR_SLEEP0 register is at offset (0x2 << 2) rather than (0x3a << 2). As result of this (0x38 << 2) is subtracted from the register offsets, which is the start of the power management related registers.

The power domains on the 32-bit Meson8/Meson8b/Meson8m2 SoCs are very similar to what G12A still uses. The (known) differences are: - Meson8 doesn't use any reset lines at all - Meson8b and Meson8m2 use the same reset lines, which are different from what the 64-bit SoCs use - there is no "vapb" clock on the older SoCs - amlogic,ao-sysctrl cannot point to the whole AO sysctrl region but only the power management related registers Add a new compatible string and adjust clock and reset line expectations for each SoC.

2020-05-06firmware: tf: Different way of L2 cache enabling after LP2 suspendDmitry Osipenko2-2/+20
ASUS TF300T device may not work properly if firmware is asked to fully re-initialize L2 cache after resume from LP2 suspend. The downstream kernel of TF300T uses different opcode to enable cache after resuming from LP2, this opcode also works fine on Nexus 7 and Ouya devices. Supposedly, this may be needed by an older firmware versions.

2020-05-01iommu/amd: Fix legacy interrupt remapping for x2APIC-enabled systemSuravee Suthikulpanit1-1/+1
Currently, system fails to boot because the legacy interrupt remapping mode does not enable 128-bit IRTE (GA), which is required for x2APIC support. Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with kernel option amd_iommu_intr=legacy instead. The initialization logic will check GASup and automatically fallback to using AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

2020-05-01io_uring: use cond_resched() in io_ring_ctx_wait_and_kill()Xiaoguang Wang1-1/+1
While working on to make io_uring sqpoll mode support syscalls that need struct files_struct, I got cpu soft lockup in io_ring_ctx_wait_and_kill(), while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait)) cpu_relax(); above loop never has an chance to exit, it's because preempt isn't enabled in the kernel, and the context calling io_ring_ctx_wait_and_kill() and io_sq_thread() run in the same cpu, if io_sq_thread calls a cond_resched() yield cpu and another context enters above loop, then io_sq_thread() will always in runqueue and never exit. Use cond_resched() can fix this issue.
