2022-05-13bnxt_en: parse and report result field when NVRAM package install failsKalesh AP3-13/+72
Instead of always returning -ENOPKG, decode the firmware error code further when the HWRM_NVM_INSTALL_UPDATE firmware call fails. Return a more suitable error code to userspace and log an error in dmesg. This is version 2 of the earlier patch that was reverted: 02acd399533e ("bnxt_en: parse result field when NVRAM package install fails") In this new version, if the call is made through devlink instead of ethtool, we'll also set the error message in extack.

2022-05-13bnxt_en: Configure ptp filters during bnxt openPavan Chebbi3-13/+46
For correctness, we need to configure the packet filters for timestamping during bnxt_open. This way they are always configured after firmware reset or chip reset. We should not assume that the filters will always be retained across resets. This patch modifies the ioctl handler and always configures the PTP filters in the bnxt_open() path.

2022-05-13platform/chrome: Add ChromeOS ACPI device driverEnric Balletbo i Serra6-0/+759
The x86 Chromebooks have the ChromeOS ACPI device. This driver attaches to the ChromeOS ACPI device and exports the values reported by ACPI in a sysfs directory. This data isn't present in ACPI tables when read through ACPI tools, hence a driver is needed to do it. The driver gets data from firmware using the ACPI component of the kernel. The ACPI values are presented in string form (numbers as decimal values) or binary blobs, and can be accessed as the contents of the appropriate read only files in the standard ACPI device's sysfs directory tree. This data is consumed by the ChromeOS user space.

2022-05-13dma-buf: ensure unique directory name for dmabuf statsCharan Teja Kalla1-0/+8
The dmabuf file uses get_next_ino()(through dma_buf_getfile() -> alloc_anon_inode()) to get an inode number and uses the same as a directory name under /sys/kernel/dmabuf/buffers/<ino>. This directory is used to collect the dmabuf stats and it is created through dma_buf_stats_setup(). At current, failure to create this directory entry can make the dma_buf_export() to fail. Now, as the get_next_ino() can definitely give a repetitive inode no causing the directory entry creation to fail with -EEXIST. This is a problem on the systems where dmabuf stats functionality is enabled on the production builds can make the dma_buf_export(), though the dmabuf memory is allocated successfully, to fail just because it couldn't create stats entry. This issue we are able to see on the snapdragon system within 13 days where there already exists a directory with inode no "122602" so dma_buf_stats_setup() failed with -EEXIST as it is trying to create the same directory entry. To make the dentry name as unique, use the dmabuf fs specific inode which is based on the simple atomic variable increment. There is tmpfs subsystem too which relies on its own inode generation rather than relying on the get_next_ino() for the same reason of avoiding the duplicate inodes[1].

2022-05-13KVM: PPC: Book3S HV Nested: L2 LPCR should inherit L1 LPES settingNicholas Piggin2-2/+5
The L1 should not be able to adjust LPES mode for the L2. Setting LPES if the L0 needs it clear would cause external interrupts to be sent to L2 and missed by the L0. Clearing LPES when it may be set, as typically happens with XIVE enabled could cause a performance issue despite having no native XIVE support in the guest, because it will cause mediated interrupts for the L2 to be taken in HV mode, which then have to be injected.

2022-05-13KVM: PPC: Book3S HV Nested: L2 must not run with L1 xive contextNicholas Piggin2-7/+21
The PowerNV L0 currently pushes the OS xive context when running a vCPU, regardless of whether it is running a nested guest. The problem is that xive OS ring interrupts will be delivered while the L2 is running. At the moment, by default, the L2 guest runs with LPCR[LPES]=0, which actually makes external interrupts go to the L0. That causes the L2 to exit and the interrupt taken or injected into the L1, so in some respects this behaves like an escalation. It's not clear if this was deliberate or not, there's no comment about it and the L1 is actually allowed to clear LPES in the L2, so it's confusing at best. When the L2 is running, the L1 is essentially in a ceded state with respect to external interrupts (it can't respond to them directly and won't get scheduled again absent some additional event). So the natural way to solve this is when the L0 handles a H_ENTER_NESTED hypercall to run the L2, have it arm the escalation interrupt and don't push the L1 context while running the L2.

2022-05-13net: axienet: Use NAPI for TX completion pathRobert Hancock2-85/+111
This driver was using the TX IRQ handler to perform all TX completion tasks. Under heavy TX network load, this can cause significant irqs-off latencies (found to be in the hundreds of microseconds using ftrace). This can cause other issues, such as overrunning serial UART FIFOs when using high baud rates with limited UART FIFO sizes. Switch to using a NAPI poll handler to perform the TX completion work to get this out of hard IRQ context and avoid the IRQ latency impact. A separate poll handler is used for TX and RX since they have separate IRQs on this controller, so that the completion work for each of them stays on the same CPU as the interrupt. Testing on a Xilinx MPSoC ZU9EG platform using iperf3 from a Linux PC through a switch at 1G link speed showed no significant change in TX or RX throughput, with approximately 941 Mbps before and after. Hard IRQ time in the TX throughput test was significantly reduced from 12% to below 1% on the CPU handling TX interrupts, with total hard+soft IRQ CPU usage dropping from about 56% down to 48%.

Move power_on work cancel to hci_dev_close_sync to ensure that power_on work is canceled after HCI interface down, power off, rfkill, etc. For example, if hciconfig hci0 down is done early enough during boot, it may run before power_on work.

2022-05-13Bluetooth: protect le accept and resolv lists with hdev->lockNiels Dossche1-0/+12
Concurrent operations from events on le_{accept,resolv}_list are currently unprotected by hdev->lock. Most existing code do already protect the lists with that lock. This can be observed in hci_debugfs and hci_sync. Add the protection for these events too.

All accesses (both reads and modifications) to hdev->{accept,reject}_list are protected by hdev lock, except the ones in hci_conn_request_evt. This can cause a race condition in the form of a list corruption. The solution is to protect these lists in hci_conn_request_evt as well. I was unable to find the exact commit that introduced the issue for the reject list, I was only able to find it for the accept list.

Paths that leads to an unlocked call are: discov_update => start_discovery => interleaved_discov => active_scan and: discov_update => start_discovery => active_scan The solution is to take the lock in active_scan during the duration of the call to hci_is_adv_monitoring.
