[PATCH] clk: imx8mp: Fix clkout1/2 support

by Marek Vasut

The CLKOUTn may be fed from PLL1/2/3, but the PLL1/2/3 has to be enabled first by setting PLL_CLKE bit 11 in CCM_ANALOG_SYS_PLLn_GEN_CTRL register. The CCM_ANALOG_SYS_PLLn_GEN_CTRL bit 11 is modeled by plln_out clock. Fix the clock tree and place the clkout1/2 under plln_sel instead of plain plln to let the clock subsystem correctly control the bit 11 and enable the PLL in case the CLKOUTn is supplied by PLL1/2/3.

[PATCH 3/5] usb: xhci: Fix NULL pointer dereference on certain command aborts

by Mathias Nyman

From: Michal Pecio <michal.pecio(a)gmail.com> If a command is queued to the final usable TRB of a ring segment, the enqueue pointer is advanced to the subsequent link TRB and no further. If the command is later aborted, when the abort completion is handled the dequeue pointer is advanced to the first TRB of the next segment. If no further commands are queued, xhci_handle_stopped_cmd_ring() sees the ring pointers unequal and assumes that there is a pending command, so it calls xhci_mod_cmd_timer() which crashes if cur_cmd was NULL. Don't attempt timer setup if cur_cmd is NULL. The subsequent doorbell ring likely is unnecessary too, but it's harmless. Leave it alone. This is probably Bug 219532, but no confirmation has been received. The issue has been independently reproduced and confirmed fixed using a USB MCU programmed to NAK the Status stage of SET_ADDRESS forever. Everything continued working normally after several prevented crashes.

[PATCH] clk: qcom: clk-alpha-pll: fix alpha mode configuration

by Gabor Juhos

Commit c45ae598fc16 ("clk: qcom: support for alpha mode configuration") added support for configuring alpha mode, but it seems that the feature was never working in practice. The value of the alpha_{en,mode}_mask members of the configuration gets added to the value parameter passed to the regmap_update_bits() function, however the same values are not getting applied to the bitmask. As the result, the respective bits in the USER_CTL register are never modifed which leads to improper configuration of several PLLs. The following table shows the PLL configurations where the 'alpha_en_mask' member is set and which are passed as a parameter for the clk_alpha_pll_configure() function. In the table the 'expected rate' column shows the rate the PLL should run at with the given configuration, and the 'real rate' column shows the rate the PLL runs at actually. The real rates has been verified on hardwareOn IPQ* platforms, on other platforms, those are computed values only. file pll expected rate real rate dispcc-qcm2290.c disp_cc_pll0 768.0 MHz 768.0 MHz dispcc-sm6115.c disp_cc_pll0 768.0 MHz 768.0 MHz gcc-ipq5018.c ubi32_pll 1000.0 MHz != 984.0 MHz gcc-ipq6018.c nss_crypto_pll 1200.0 MHz 1200.0 MHz gcc-ipq6018.c ubi32_pll 1497.6 MHz != 1488.0 MHz gcc-ipq8074.c nss_crypto_pll 1200.0 MHz != 1190.4 MHz gcc-qcm2290.c gpll11 532.0 MHz != 518.4 MHz gcc-qcm2290.c gpll8 533.2 MHz != 518.4 MHz gcc-qcs404.c gpll3 921.6 MHz 921.6 MHz gcc-sm6115.c gpll11 600.0 MHz != 595.2 MHz gcc-sm6115.c gpll8 800.0 MHz != 787.2 MHz gpucc-sdm660.c gpu_cc_pll0 800.0 MHz != 787.2 MHz gpucc-sdm660.c gpu_cc_pll1 740.0 MHz != 729.6 MHz gpucc-sm6115.c gpu_cc_pll0 1200.0 MHz != 1190.4 MHz gpucc-sm6115.c gpu_cc_pll1 640.0 MHz != 633.6 MHz gpucc-sm6125.c gpu_pll0 1020.0 MHz != 1017.6 MHz gpucc-sm6125.c gpu_pll1 930.0 MHz != 921.6 MHz mmcc-sdm660.c mmpll8 930.0 MHz != 921.6 MHz mmcc-sdm660.c mmpll5 825.0 MHz != 806.4 MHz As it can be seen from the above, there are several PLLs which are configured incorrectly. Change the code to apply both 'alpha_en_mask' and 'alpha_mode_mask' values to the bitmask in order to configure the alpha mode correctly. Applying the 'alpha_en_mask' fixes the initial rate of the PLLs showed in the table above. Since the 'alpha_mode_mask' is not used by any driver currently, that part of the change causes no functional changes.

[PATCH] scripts/sorttable: Fix orc_sort_cmp() to maintain symmetry and transitivity

by Kuan-Wei Chiu

The orc_sort_cmp() function, used with qsort(), previously violated the symmetry and transitivity rules required by the C standard. Specifically, when both entries are ORC_TYPE_UNDEFINED, it could result in both a < b and b < a, which breaks the required symmetry and transitivity. This can lead to undefined behavior and incorrect sorting results, potentially causing memory corruption in glibc implementations [1]. Symmetry: If x < y, then y > x. Transitivity: If x < y and y < z, then x < z. Fix the comparison logic to return 0 when both entries are ORC_TYPE_UNDEFINED, ensuring compliance with qsort() requirements.

As a result, this lead to soft lockup in the OOM process. To fix this issue, call 'cond_resched' in the 'mem_cgroup_scan_tasks' function per 1000 iterations. For global OOM, call 'touch_softlockup_watchdog' per 1000 iterations to avoid this issue.
