tx-fifo-resize is now added by default by the dwc3-qcom driver to the SNPS DWC3 child node. So, lets drop the tx-fifo-resize property from dwc3-qcom nodes as having it there will cause the dwc3-qcom driver to error and abort probe with: [ 1.362938] dwc3-qcom 8af8800.usb: unable to add property [ 1.368405] dwc3-qcom 8af8800.usb: failed to register DWC3 Core, err=-17 Fixes: cefdd52f ("usb: dwc3: dwc3-qcom: Enable tx-fifo-resize property by default") Signed-off-by: Robert Marko <robimarko@gmail.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org> Link: https://lore.kernel.org/r/20210902220325.1783567-1-robimarko@gmail.com

The sc7180's dynamic-power-coefficient violates the device tree bindings. The bindings (arm/cpus.yaml) say that the units for the dynamic-power-coefficient are supposed to be "uW/MHz/V^2". The ones for sc7180 aren't this. Qualcomm arbitrarily picked 100 for the "little" CPUs and then picked a number for the big CPU based on this. At the time, there was a giant dicussion about this. Apparently Qualcomm Engineers were instructed not to share the actual numbers here. As part of the discussion, I pointed out [1] that these numbers shouldn't really be secret since once a device is shipping anyone can just run a script and produce them. This patch is the result of running the script I posted in that discussion on sc7180-trogdor-coachz, which is currently available for purchase by consumers. [1] https://lore.kernel.org/r/CAD=FV=U1FP0e3_AVHpauUUZtD-5X3XCwh5aT9fH_8S_FFML2Uw@mail.gmail.com/ I ran the script four times, measuring little, big, little, big. I used the 64-bit version of dhrystone 2.2 in my test. I got these results: 576 kHz, 596 mV, 20 mW, 88 Cx 768 kHz, 596 mV, 32 mW, 122 Cx 1017 kHz, 660 mV, 45 mW, 97 Cx 1248 kHz, 720 mV, 87 mW, 139 Cx 1324 kHz, 756 mV, 109 mW, 148 Cx 1516 kHz, 828 mV, 150 mW, 148 Cx 1612 kHz, 884 mV, 182 mW, 147 Cx 1708 kHz, 884 mV, 192 mW, 146 Cx 1804 kHz, 884 mV, 207 mW, 149 Cx Your dynamic-power-coefficient for cpu 0: 132 825 kHz, 596 mV, 142 mW, 401 Cx 979 kHz, 628 mV, 183 mW, 427 Cx 1113 kHz, 656 mV, 224 mW, 433 Cx 1267 kHz, 688 mV, 282 mW, 449 Cx 1555 kHz, 812 mV, 475 mW, 450 Cx 1708 kHz, 828 mV, 566 mW, 478 Cx 1843 kHz, 884 mV, 692 mW, 476 Cx 1900 kHz, 884 mV, 722 mW, 482 Cx 1996 kHz, 916 mV, 814 mW, 482 Cx 2112 kHz, 916 mV, 862 mW, 483 Cx 2208 kHz, 916 mV, 962 mW, 521 Cx 2323 kHz, 940 mV, 1060 mW, 517 Cx 2400 kHz, 956 mV, 1133 mW, 518 Cx Your dynamic-power-coefficient for cpu 6: 471 576 kHz, 596 mV, 26 mW, 103 Cx 768 kHz, 596 mV, 40 mW, 147 Cx 1017 kHz, 660 mV, 54 mW, 114 Cx 1248 kHz, 720 mV, 97 mW, 151 Cx 1324 kHz, 756 mV, 113 mW, 150 Cx 1516 kHz, 828 mV, 154 mW, 148 Cx 1612 kHz, 884 mV, 194 mW, 155 Cx 1708 kHz, 884 mV, 203 mW, 152 Cx 1804 kHz, 884 mV, 219 mW, 155 Cx Your dynamic-power-coefficient for cpu 0: 142 825 kHz, 596 mV, 148 mW, 530 Cx 979 kHz, 628 mV, 189 mW, 475 Cx 1113 kHz, 656 mV, 230 mW, 461 Cx 1267 kHz, 688 mV, 287 mW, 466 Cx 1555 kHz, 812 mV, 469 mW, 445 Cx 1708 kHz, 828 mV, 567 mW, 480 Cx 1843 kHz, 884 mV, 699 mW, 482 Cx 1900 kHz, 884 mV, 719 mW, 480 Cx 1996 kHz, 916 mV, 814 mW, 484 Cx 2112 kHz, 916 mV, 861 mW, 483 Cx 2208 kHz, 916 mV, 963 mW, 522 Cx 2323 kHz, 940 mV, 1063 mW, 520 Cx 2400 kHz, 956 mV, 1135 mW, 519 Cx Your dynamic-power-coefficient for cpu 6: 489 As you can see, the calculations aren't perfectly consistent but roughly you could say about 480 for big and 137 for little. The ratio between these numbers isn't quite the same as the ratio between the two numbers that Qualcomm used. Perhaps this is because Qualcomm measured something slightly different than the 64-bit version of dhrystone 2.2 or perhaps it's because they fudged these numbers a bit (and fudged the capacity-dmips-mhz). As per discussion [2], let's use the numbers I came up with and also un-fudge capacity-dmips-mhz. While unfudging capacity-dmips-mhz, let's scale it so that bigs are 1024 which seems to be the common practice. In general these numbers don't need to be perfectly exact. In fact, they can't be since the CPU power depends a lot on what's being run on the CPU and the big/little CPUs are each more or less efficient in different operations. Historically running the 32-bit vs. 64-bit versions of dhrystone produced notably different numbers, though I didn't test this time. We also need to scale all of the sustainable-power numbers by the same amount. I scale ones related to the big CPUs by the adjustment I made to the big dynamic-power-coefficient and the ones related to the little CPUs by the adjustment I made to the little dynamic-power-coefficient.

The MSM8998 SoC includes an Adreno 540.1 GPU, with a maximum frequency of 710MHz.

The QFPROM iospace was (erroneously, I believe) set to the uncalibrated fuse start address, but every driver only needs - and will always only need - only calibrated values. Move the iospace forward to the calibrated values start to avoid offsetting every fuse definition. Obviously, the only defined fuse (qusb2_hstx_trim) was also fixed to remove the offset, in order to comply with this change.

The entry/exit latency and minimum residency in state for the idle states of MSM8998 were ..bad: first of all, for all of them the timings were written for CPU sleep but the min-residency-us param was miscalculated (supposedly, while porting this from downstream); Then, the power collapse states are setting PC on both the CPU cluster *and* the L2 cache, which have different timings: in the specific case of L2 the times are higher so these ones should be taken into account instead of the CPU ones. This parameter misconfiguration was not giving particular issues because on MSM8998 there was no CPU scaling at all, so cluster/L2 power collapse was rarely (if ever) hit. When CPU scaling is enabled, though, the wrong timings will produce SoC unstability shown to the user as random, apparently error-less, sudden reboots and/or lockups. This set of parameters are stabilizing the SoC when CPU scaling is ON and when power collapse is frequently hit.

In commit 3e482859 ("dts: qcom: sdm845: Add dt entries to support crypto engine."), we decided to use the value indicated by constant RPMH_CE_CLK rather than using it directly. Now that the same RPMH clock value might be used for other SoCs (in addition to sdm845), let's use the constant RPMH_CE_CLK to make sure that this dtsi is compatible with the other qcom ones.

Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.

A config terms list was spliced twice, resulting in a never-ending loop when the list was traversed. Fix by using list_splice_init() and copying and freeing the lists as necessary.
