Move the traversal of the program headers to the start of the function, to make sure that min_ and max_addr are in scope as the call to qcom_scm_pas_mem_setup() is moved in the next commit.

2022-02-03soc: qcom: mdt_loader: Extend check for split firmwareBjorn Andersson
Some of the Qualcomm SM8450 firmware files are padded such that the start of the first segment falls within the .mdt file but the segment to be loaded is stored as a separate .bNN file. Extend the condition to only attempt to read a segment inline if the entire segment would be available.

2022-02-03soc: qcom: mdt_loader: Allow hash segment to be split outBjorn Andersson
It's been observed that some firmware found in a Qualcomm SM8450 device has the hash table in a separate .bNN file. Use the newly extracted helper function to load this segment from the separate file, if it's determined that the hashes are not part of the already loaded firmware. In order to do this, the function needs access to the firmware basename and to provide more useful error messages a struct device to associate the errors with.

2022-02-03soc: qcom: mdt_loader: Split out split-file-loaderBjorn Andersson
Spotted in a SM8450 device, the hash metadata segment is split out in a separate .bNN file which means that the logic for loading split out segmenents needs to be duplicated in qcom_mdt_read_metadata(). Split out the existing logic to a helper function that can be used in both code paths.

2022-02-03firmware: qcom: scm: Introduce pas_metadata contextBjorn Andersson
Starting with Qualcomm SM8450, some new security enhancements has been done in the secure world, which results in the requirement to keep the metadata segment accessible by the secure world from init_image() until auth_and_reset(). Introduce a "PAS metadata context" object that can be passed to init_image() for tracking the mapped memory and a related release function for client drivers to release the mapping once either auth_and_reset() has been invoked or in error handling paths on the way there.

2022-01-31soc: qcom: aoss: remove spurious IRQF_ONESHOT flagsDaniel Thompson
Quoting the header comments, IRQF_ONESHOT is "Used by threaded interrupts which need to keep the irq line disabled until the threaded handler has been run.". When applied to an interrupt that doesn't request a threaded irq then IRQF_ONESHOT has a lesser known (undocumented?) side effect, which it to disable the forced threading of the irq. For "normal" kernels (without forced threading) then, if there is no thread_fn, then IRQF_ONESHOT is a nop. In this case disabling forced threading is not appropriate for this driver because it calls wake_up_all() and this API cannot be called from no-thread interrupt handlers on PREEMPT_RT systems (deadlock risk, triggers sleeping-while-atomic warnings). Fix this by removing IRQF_ONESHOT.

The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one.

2022-01-23ftrace: Fix assuming build time sort works for s390Steven Rostedt (Google)
To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.

2022-01-22perf script: Fix printing 'phys_addr' failure issueYao Jin
Perf script was failed to print the phys_addr for SPE profiling. One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR attribute set, perf script then exits with error. Now referring to 'addr', use evsel__do_check_stype() to check the type. Before: # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\ store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3 # perf script -F pid,tid,addr,phys_addr Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field. After: # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\ store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3 # perf script -F pid,tid,addr,phys_addr 4064384/4064384 ffff802f921be0d0 2f921be0d0 4064384/4064384 ffff802f921be0d0 2f921be0d0 Reviewed-by: German Gomez <german.gomez@arm.com> Signed-off-by: Yao Jin <jinyao5@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Hanjun Guo <guohanjun@huawei.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20220121065954.2121900-1-liwei391@huawei.com Signed-off-by: Wei Li <liwei391@huawei.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
