2022-10-15perf test: test_intel_pt.sh: Add 9 testsAmmy Yi1-1/+194
Add tests: Test with MTC and TSC disabled Test with branches disabled Test with/without CYC Test recording with sample mode Test with kernel trace Test virtual LBR Test power events Test with TNT packets disabled Test with event_trace These tests mostly check that perf record works with the corresponding Intel PT config terms, sometimes also checking that certain packets do or do not appear in the resulting trace as appropriate. The "Test virtual LBR" is slightly trickier, using a Python script to check that branch stacks are actually synthesized.

2022-10-15perf test: test_intel_pt.sh: Add jitdump testAdrian Hunter1-0/+162
Add a test for decoding self-modifying code using a jitdump file. The test creates a workload that uses self-modifying code and generates its own jitdump file. The result is processed with perf inject --jit and checked for decoding errors. Note the test will fail without patch "perf inject: Fix GEN_ELF_TEXT_OFFSET for jit" applied.

2022-10-14clk: tegra: Fix Tegra PWM parent clockJon Hunter5-0/+5
Commit 8c193f4714df ("pwm: tegra: Optimize period calculation") updated the period calculation in the Tegra PWM driver and now returns an error if the period requested is less than minimum period supported. This is breaking PWM support on various Tegra platforms. For example, on the Tegra210 Jetson Nano platform this is breaking the PWM fan support and probing the PWM fan driver now fails ... pwm-fan pwm-fan: Failed to configure PWM: -22 pwm-fan: probe of pwm-fan failed with error -22 The problem is that the default parent clock for the PWM on Tegra210 is a 32kHz clock and is unable to support the requested PWM period. Fix PWM support on Tegra20, Tegra30, Tegra114, Tegra124 and Tegra210 by updating the parent clock for the PWM to be the PLL_P.

These two clocks are now registered in the device tree as fixed clocks, causing a regression in the driver as the clock already exists with e.g. the name "pxo_board" as the MSM8660 GCC driver probes.

2022-10-14clk: mediatek: clk-mux: Add .determine_rate() callbackAngeloGioacchino Del Regno1-0/+10
Since commit 262ca38f4b6e ("clk: Stop forwarding clk_rate_requests to the parent"), the clk_rate_request is .. as the title says, not forwarded anymore to the parent: this produces an issue with the MediaTek clock MUX driver during GPU DVFS on MT8195, but not on MT8192 or others. This is because, differently from others, like MT8192 where all of the clocks in the MFG parents tree are of mtk_mux type, but in the parent tree of MT8195's MFG clock, we have one mtk_mux clock and one (clk framework generic) mux clock, like so: names: mfg_bg3d -> mfg_ck_fast_ref -> top_mfg_core_tmp (or) mfgpll types: mtk_gate -> mux -> mtk_mux (or) mtk_pll To solve this issue and also keep the GPU DVFS clocks code working as expected, wire up a .determine_rate() callback for the mtk_mux ops; for that, the standard clk_mux_determine_rate_flags() was used as it was possible to. This commit was successfully tested on MT6795 Xperia M5, MT8173 Elm, MT8192 Spherion and MT8195 Tomato; no regressions were seen.

2022-10-14kbuild: add -fno-discard-value-names to cmd_cc_ll_cNick Desaulniers1-1/+1
When debugging LLVM IR, it can be handy for clang to not discard value names used for local variables and parameters. Compare the generated IR. -fdiscard-value-names: define i32 @core_sys_select(i32 %0, ptr %1, ptr %2, ptr %3, ptr %4) { %6 = alloca i64 %7 = alloca %struct.poll_wqueues %8 = alloca [64 x i32] -fno-discard-value-names: define i32 @core_sys_select(i32 %n, ptr %inp, ptr %outp, ptr %exp, ptr %end_time) { %expire.i = alloca i64 %table.i = alloca %struct.poll_wqueues %stack_fds = alloca [64 x i32] The rule for generating human readable LLVM IR (.ll) is only useful as a debugging feature: $ make LLVM=1 fs/select.ll As Fangrui notes: A LLVM_ENABLE_ASSERTIONS=off build of Clang defaults to -fdiscard-value-names. A LLVM_ENABLE_ASSERTIONS=on build of Clang defaults to -fno-discard-value-names. Explicitly enable -fno-discard-value-names so that the IR always contains value names regardless of whether assertions were enabled or not. Assertions generally are not enabled in releases of clang packaged by distributions.

2022-10-14perf: Skip and warn on unknown format 'configN' attrsRob Herring5-13/+26
If the kernel exposes a new perf_event_attr field in a format attr, perf will return an error stating the specified PMU can't be found. For example, a format attr with 'config3:0-63' causes an error as config3 is unknown to perf. This causes a compatibility issue between a newer kernel with older perf tool. Before this change with a kernel adding 'config3' I get: $ perf record -e arm_spe// -- true event syntax error: 'arm_spe//' \___ Cannot find PMU `arm_spe'. Missing kernel support? Run 'perf list' for a list of valid events Usage: perf record [<options>] [<command>] or: perf record [<options>] -- <command> [<options>] -e, --event <event> event selector. use 'perf list' to list available events After this change, I get: $ perf record -e arm_spe// -- true WARNING: 'arm_spe_0' format 'inv_event_filter' requires 'perf_event_attr::config3' which is not supported by this version of perf! [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 0.091 MB perf.data ] To support unknown configN formats, rework the YACC implementation to pass any config[0-9]+ format to perf_pmu__new_format() to handle with a warning.

2022-10-14parisc: Fix userspace graphics card breakage due to pgtable special bitHelge Deller2-1/+14
Commit df24e1783e6e ("parisc: Add vDSO support") introduced the vDSO support, for which a _PAGE_SPECIAL page table flag was needed. Since we wanted to keep every page table entry in 32-bits, this patch re-used the existing - but yet unused - _PAGE_DMB flag (which triggers a hardware break if a page is accessed) to store the special bit. But when graphics card memory is mmapped into userspace, the kernel uses vm_iomap_memory() which sets the the special flag. So, with the DMB bit set, every access to the graphics memory now triggered a hardware exception and segfaulted the userspace program. Fix this breakage by dropping the DMB bit when writing the page protection bits to the CPU TLB. In addition this patch adds a small optimization: if huge pages aren't configured (which is at least the case for 32-bit kernels), then the special bit is stored in the hpage (HUGE PAGE) bit instead. That way we can skip to reset the DMB bit. Fixes: df24e1783e6e ("parisc: Add vDSO support") Cc: <stable@vger.kernel.org> # 5.18+ Signed-off-by: Helge Deller <deller@gmx.de>
