Incase of trace records that are being read from pstore, the numerical
*pos is not enough to hold state from session to session. A trace
iterator is better suited for this. So for PSTORE_TYPE_TRACE record
types, the seq_file->private field holds pointer to trace_iterator and not
pstore_private. For
Add a new trace_array, pstore_trace. This descriptor holds the
top-level buffers used for managing the pages retrieved from
persistent RAM. Since pstore_trace uses the pages that pertain to
previous boot, there is no write that happens to these buffers. The
reads are non-consuming and hence we do n
ramtrace backend acts as a page allocator and manages
the persistent RAM buffer.
ramtrace supports allocation and deallocation of page-sized memory
through methods, ramtrace_alloc_page and ramtrace_free_page.
This functionality is required by ring buffer in trace when the user
switches to persiste
Add support in ring buffer to allocate pages from persistent RAM
buffer. This feature supports switching to persistent memory and vice-versa.
A new option 'persist' has been added and once this is enabled, the pages in
ring buffer are freed up and new pages are allocated from persistent
memory.

Hi,
This patch series adds support to store trace events in pstore.
Storing trace entries in persistent RAM would help in understanding what
happened just before the system went down. The trace events that led to the
crash can be retrieved from the pstore after a warm reboot. This will help

The Color Matching Descriptor has been present in USB cameras since
the original version of UVC, but it has never been fully exposed
in Linux.
This change informs V4L2 of all of the UVC colorspace parameters:

On RM400(a20r) machines ISA and SCSI interrupts share the same interrupt
line. Commit 49e6e07e3c80 ("MIPS: pass non-NULL dev_id on shared

ISA interrupt.

The same nvme and pcie hotplug drivers are used with or

During Plumbers 2020, we voted to just support the latest release of
Clang for now. Add a compile time check for this.
We plan to remove workarounds for older versions now, which will break

As Kees suggests, doing so provides developers with two useful pieces of

- The kernel build was attempting to use GCC.
(Maybe they accidentally poked the wrong configs in a CI.)
- They need 4.9 or better.

This also removes the PLL code and adds proper includes so things build.

The dp_com resource is always at index 1 according to the dts files in
