b6fd6e0f5e drm/amdgpu: Check the memory can be accesssed by ttm_device_clear_dma_mappings.
If the event guard is enabled and VF doesn't receive an ack from PF for full access,
the guest driver load crashes.
This is caused due to the call to ttm_device_clear_dma_mappings with non-initialized
mman during driver tear down.

This patch adds the necessary condition to check if the mman initialization passed or not
and takes the path based on the condition output.

f89c6bf734 drm/amdkfd: correct sdma queue number in kfd device init (v3)
This patch keeps the setting of sdma queue number to the same
after recent KFD code refactor. Additionally, improve code to
use switch case to list IP version to complete kfd device_info
structure filling for IH version assignment. This makes consistency
with the IP parse code in amdgpu_discovery.c.

v2: use dev_warn for the default switch case;
    set default sdma queue per engine(8) and IH handler to v9. (Jonathan)

v3: Fix missed IP version check of Raven.

87172e89dc drm/amdgpu: Call amdgpu_device_unmap_mmio() if device is unplugged to prevent crash in GPU initialization failure
[Why]
In amdgpu_driver_load_kms, when amdgpu_device_init returns error during driver modprobe, it
will start the error handle path immediately and call into amdgpu_device_unmap_mmio as well
to release mapped VRAM. However, in the following release callback, driver stills visits the
unmapped memory like vcn.inst[i].fw_shared_cpu_addr in vcn_v3_0_sw_fini. So a kernel crash occurs.

[How]
call amdgpu_device_unmap_mmio() if device is unplugged to prevent invalid memory address in
vcn_v3_0_sw_fini() when GPU initialization failure.

Add support to enable flow-director filter when multiple TCs are

(--config-ntuple option). When multiple TCs are configured, each
TC is mapped to an unique HW VSI. So VSI corresponding to queue
used in filter is identified and flow director context is updated
with correct VSI while configuring ntuple filter in HW.

====================
1GbE Intel Wired LAN Driver Updates 2021-12-29

Ruud Bos says:

The igb driver provides support for PEROUT and EXTTS pin functions that
allow adapter external use of timing signals. At Hottinger Bruel & Kjaer we
are using the PEROUT function to feed a PTP corrected 1pps signal into an
FPGA as cross system synchronized time source.

Support for the PEROUT and EXTTS SDP functions is currently limited to
i210/i211 based adapters. This patch series enables these functions also
for 82580/i354/i350 based ones. Because the time registers of these
adapters do not have the nice split in second rollovers as the i210 has,
the implementation is slightly more complex compared to the i210
implementation.

The PEROUT function has been successfully tested on an i350 based ethernet
adapter. Using the following user space code excerpt, the driver outputs a
PTP corrected 1pps signal on the SDP0 pin of an i350:

    struct ptp_pin_desc desc;
    memset(&desc, 0, sizeof(desc));
    desc.index = 0;
    desc.func = PTP_PF_PEROUT;
    desc.chan = 0;
    if (ioctl(fd, PTP_PIN_SETFUNC, &desc) == 0) {
        struct timespec ts;
        if (clock_gettime(clkid, &ts) == 0) {
            struct ptp_perout_request rq;
            memset(&rq, 0, sizeof(rq));
            rq.index = 0;
            rq.start.sec = ts.tv_sec + 1;
            rq.start.nsec = 500000000;
            rq.period.sec  = 1;
            rq.period.nsec = 0;
            if (ioctl(fd, PTP_PEROUT_REQUEST, &rq) == 0) {
                /* 1pps signal is now available on SDP0 */
            }
        }
    }

The added EXTTS function has not been tested. However, looking at the data
sheets, the layout of the registers involved match the i210 exactly except
for the time registers mentioned before. Hence the almost identical
implementation.

unnecessary parenthesis.

for subscribing and parsing kernel structures, and another
(prestera_router_hw.c) for HW objects relations tracking.

There is two types of objects on router_hw layer:

 - Implicit objects (vr) : created on demand by explicit objects.

a41f5b78ac x86/vdso: Remove -nostdlib compiler flag
The -nostdlib option requests the compiler to not use the standard
system startup files or libraries when linking. It is effective only
when $(CC) is used as a linker driver.

Since

  379d98ddf4 ("x86: vdso: Use $LD instead of $CC to link")

$(LD) is directly used, hence -nostdlib is unneeded.

28f0c335dd devtmpfs: mount with noexec and nosuid
devtmpfs is writable. Add the noexec and nosuid as default mount flags
to prevent code execution from /dev. The systems who don't use systemd
and who rely on CONFIG_DEVTMPFS_MOUNT=y are the ones to be protected by
this patch. Other systems are fine with the udev solution.

No sane program should be relying on executing from /dev. So this patch
reduces the attack surface. It doesn't prevent any specific attack, but
it reduces the possibility that someone can use /dev as a place to put
executable code. Chrome OS has been carrying this patch for several
years. It seems trivial and simple solution to improve the protection of
/dev when CONFIG_DEVTMPFS_MOUNT=y.

d8e9a406a9 serdev: BREAK/FRAME/PARITY/OVERRUN notification prototype V2
Allow serdev device drivers get notified by hardware errors such as BREAK,
FRAME, PARITY and OVERRUN.

With this patch, in the event of an error detected in the UART device driver
the serdev_device_driver will get the newly introduced ->error() callback
invoked if serdev_device_set_error_mask() has previously been used to enable
the type of error. The errors are taken straight from the TTY layer and fed
into the serdev_device_driver after filtering out only enabled errors.

Without this patch the hardware errors never reach the serdev_device_driver.
