2026-01-05x86,fs/resctrl: Use struct rdt_domain_hdr when reading countersTony Luck
Convert the whole call sequence from mon_event_read() to resctrl_arch_rmid_read() to pass resource independent struct rdt_domain_hdr instead of an L3 specific domain structure to prepare for monitoring events in other resources. This additional layer of indirection obscures which aspects of event counting depend on a valid domain. Event initialization, support for assignable counters, and normal event counting implicitly depend on a valid domain while summing of domains does not. Split summing domains from the core event counting handling to make their respective dependencies obvious.

2026-01-05x86/sev: Disable GCOV on noinstr objectBrendan Jackman
With Debian clang version 19.1.7 (3+build5) there are calls to kasan_check_write() from __sev_es_nmi_complete(), which violates noinstr. Fix it by disabling GCOV for the noinstr object, as has been done for previous such instrumentation issues. Note that this file already disables __SANITIZE_ADDRESS__ and __SANITIZE_THREAD__, thus calls like kasan_check_write() ought to be nops regardless of GCOV. This has been fixed in other patches. However, to avoid any other accidental instrumentation showing up, (and since, in principle GCOV is instrumentation and hence should be disabled for noinstr code anyway), disable GCOV overall as well.

2026-01-04x86/split_lock: Remove dead string when split_lock_detect=fatalRong Zhang
sld_state_show() has a dead str1 below: if (A) { ... } else if (B) { pr_info(... A ? str1 : str2 ...); } where A is always false in the second block, implied by the "if (A) else" pattern. Hence, str2 is always used. This seems to be some mysterious legacy inherited from the earlier patch revisions of ebb1064e7c2e ("x86/traps: Handle #DB for bus lock"). Earlier revisions¹ did enable both sld and bld at the same time to detect non-WB bus_locks when split_lock_detect=fatal, but that's no longer true in the merged revision. Remove it and translate the pr_info() into its equivalent form. ¹ https://lore.kernel.org/r/20201121023624.3604415-3-fenghua.yu@intel.com [ bp: Massage commit message; simplify braces ] Signed-off-by: Rong Zhang <i@rong.moe> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Link: https://patch.msgid.link/20251215182907.152881-1-i@rong.moe
2026-01-04x86,fs/resctrl: Refactor domain create/remove using struct rdt_domain_hdrTony Luck
Up until now, all monitoring events were associated with the L3 resource and it made sense to use the L3 specific "struct rdt_mon_domain *" argument to functions operating on domains. Telemetry events will be tied to a new resource with its instances represented by a new domain structure that, just like struct rdt_mon_domain, starts with the generic struct rdt_domain_hdr. Prepare to support domains belonging to different resources by changing the calling convention of functions operating on domains. Pass the generic header and use that to find the domain specific structure where needed.

2026-01-03arm64: dts: qcom: x1e80100: Fix USB combo PHYs SS1 and SS2 ref clocksAbel Vesa
It seems the USB combo SS1 and SS2 ref clocks have another gate, unlike the SS0. These gates are part of the TCSR clock controller. At least on Dell XPS 13 (9345), if the ref clock provided by the TCSR clock controller for SS1 PHY is disabled on the clk_disable_unused late initcall, the PHY fails to initialize. It doesn't happen on the SS0 PHY and the SS2 is not used on this device. This doesn't seem to be a problem on CRD though. It might be that the RPMh has a vote for it from some other consumer and does not actually disable it when ther kernel drops its vote. Either way, these TCSR provided clocks seem to be the correct ones for the SS1 and SS2, so use them instead.

2026-01-03arm64: dts: qcom: sdm630/660: Add CDSP-related nodesNickolay Goppen
In order to enable CDSP support for SDM660 SoC: * add shared memory p2p nodes for CDSP * add CDSP-specific smmu node * add CDSP peripheral image loader node Memory region for CDSP in SDM660 occupies the same spot as TZ buffer mem defined in sdm630.dtsi (which does not have CDSP). In sdm660.dtsi replace buffer_mem inherited from SDM630 with cdsp_region, which is also larger in size. SDM636 also doesn't have CDSP, so remove inherited from sdm660.dtsi related nodes and add buffer_mem back.

The backlight on the Hamoa IoT EVK is controlled through a PWM signal. Aligned with other x1e80100-based platforms: the PWM signal is controlled by PMK8550, and the backlight enable signal is handled by PMC8380. Describe the backlight device and connect it to the eDP panel to allow for brightness control.
