2023-06-29Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This batch of clk driver updates contains almost no new SoC support. Instead there's a treewide patch series from Maxime that makes clk_ops::determine_rate mandatory for muxes. Beyond that core framework change we have the usual pile of clk driver updates such as migrating i2c drivers to use .probe() again or YAMLfication of clk DT bindings so we can validate DTBs. Overall the SoCs that got the most updates this time around in terms of diffstat are the Amlogic and Mediatek drivers because they added new SoC support or fixed up various drivers to have proper data. In general things look kinda quiet. I suspect the core framework change may still shake out some problems after the merge window, mostly because not everyone tests linux-next where that series has been for some number of weeks. I saw that there's at least one pending fix for Tegra that needs to be wrapped up into a proper patch. I'll try to catch those bits before the window closes so that -rc1 is bootable. More details below. Core: - Make clk_ops::determine_rate mandatory for muxes New Drivers: - Add amlogic a1 SoC family PLL and peripheral clock controller support Updates: - Handle allocation failures from kasprintf() and friends - Migrate platform clk drivers to .remove_new() - Migrate i2c clk drivers to .probe() instead of .probe_new() - Remove CLK_SET_PARENT from all Mediatek MSDC core clocks - Add infra_ao reset support for Mediatek MT8188 SoCs - Align driver_data to i2c_device_id tables in some i2c clk drivers - Use device_get_match_data() in vc5 clk driver - New Kconfig symbol name (SOC_MICROCHIP_POLARFIRE) for Microchip FPGA clock drivers - Use of_property_read_bool() to read "microchip,pic32mzda-sosc" boolean DT property in clk-pic32mzda - Convert AT91 clock dt-bindings to YAML - Remove CLK_SET_RATE_PARENT flag from LDB clocks on i.MX6SX - Keep i.MX UART clocks enabled during kernel boot if earlycon is set - Drop imx_unregister_clocks() as there are no users anymore - Switch to _safe iterator on imx_clk_scu_unregister() to avoid use after free - Add determine_rate op to the imx8m composite clock - Use device managed API for iomap and kzalloc for i.MXRT1050, i.MX8MN, i.MX8MP and i.MX93 clock controller drivers - Add missing interrupt DT property for the i.MX8M clock controller - Re-add support for Exynos4212 clock controller because we are re-introducing the SoC in the mainline - Add CONFIG_OF dependency to Samsung clk Kconfig symbols to solve some objtool warnings - Preselect PLL MIPI as TCON0 parent for Allwinner A64 SoC - Convert the Renesas clock drivers to readl_poll_timeout_atomic() - Add PWM clock on Renesas R-Car V3U - Fix PLL5 on Renesas RZ/G2L and RZ/V2L" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (149 commits) clk: fix typo in clk_hw_register_fixed_rate_parent_data() macro clk: Fix memory leak in devm_clk_notifier_register() clk: mvebu: Iterate over possible CPUs instead of DT CPU nodes clk: mvebu: Use of_get_cpu_hwid() to read CPU ID MAINTAINERS: Add Marvell mvebu clock drivers clk: clocking-wizard: check return value of devm_kasprintf() clk: ti: clkctrl: check return value of kasprintf() clk: keystone: sci-clk: check return value of kasprintf() clk: si5341: free unused memory on probe failure clk: si5341: check return value of {devm_}kasprintf() clk: si5341: return error if one synth clock registration fails clk: cdce925: check return value of kasprintf() clk: vc5: check memory returned by kasprintf() clk: mediatek: clk-mt8173-apmixedsys: Fix iomap not released issue clk: mediatek: clk-mt8173-apmixedsys: Fix return value for of_iomap() error clk: mediatek: clk-mtk: Grab iomem pointer for divider clocks clk: keystone: syscon-clk: Add support for audio refclk dt-bindings: clock: Add binding documentation for TI Audio REFCLK dt-bindings: clock: ehrpwm: Remove unneeded syscon compatible clk: keystone: syscon-clk: Allow the clock node to not be of type syscon ...

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details.

2023-06-19mm: ptep_get() conversionRyan Roberts
Convert all instances of direct pte_t* dereferencing to instead use ptep_get() helper. This means that by default, the accesses change from a C dereference to a READ_ONCE(). This is technically the correct thing to do since where pgtables are modified by HW (for access/dirty) they are volatile and therefore we should always ensure READ_ONCE() semantics. But more importantly, by always using the helper, it can be overridden by the architecture to fully encapsulate the contents of the pte. Arch code is deliberately not converted, as the arch code knows best. It is intended that arch code (arm64) will override the default with its own implementation that can (e.g.) hide certain bits from the core code, or determine young/dirty status by mixing in state from another source. Conversion was done using Coccinelle: ---- // $ make coccicheck \ // COCCI=ptepget.cocci \ // SPFLAGS="--include-headers" \ // MODE=patch virtual patch @ depends on patch @ pte_t *v; @@ - *v + ptep_get(v) ---- Then reviewed and hand-edited to avoid multiple unnecessary calls to ptep_get(), instead opting to store the result of a single call in a variable, where it is correct to do so. This aims to negate any cost of READ_ONCE() and will benefit arch-overrides that may be more complex. Included is a fix for an issue in an earlier version of this patch that was pointed out by kernel test robot. The issue arose because config MMU=n elides definition of the ptep helper functions, including ptep_get(). HUGETLB_PAGE=n configs still define a simple huge_ptep_clear_flush() for linking purposes, which dereferences the ptep. So when both configs are disabled, this caused a build error because ptep_get() is not defined. Fix by continuing to do a direct dereference when MMU=n. This is safe because for this config the arch code cannot be trying to virtualize the ptes because none of the ptep helpers are defined.

2023-06-18drm/msm/a6xx: Add A610 supportKonrad Dybcio
A610 is one of (if not the) lowest-tier SKUs in the A6XX family. It features no GMU, as it's implemented solely on SoCs with SMD_RPM. What's more interesting is that it does not feature a VDDGX line either, being powered solely by VDDCX and has an unfortunate hardware quirk that makes its reset line broken - after a couple of assert/ deassert cycles, it will hang for good and will not wake up again. This GPU requires mesa changes for proper rendering, and lots of them at that. The command streams are quite far away from any other A6XX GPU and hence it needs special care. This patch was validated both by running an (incomplete) downstream mesa with some hacks (frames rendered correctly, though some instructions made the GPU hangcheck which is expected - garbage in, garbage out) and by replaying RD traces captured with the downstream KGSL driver - no crashes there, ever. Add support for this GPU on the kernel side, which comes down to pretty simply adding A612 HWCG tables, altering a few values and adding a special case for handling the reset line.

2023-06-18drm/msm/a6xx: Introduce GMU wrapper supportKonrad Dybcio
Some (particularly SMD_RPM, a.k.a non-RPMh) SoCs implement A6XX GPUs but don't implement the associated GMUs. This is due to the fact that the GMU directly pokes at RPMh. Sadly, this means we have to take care of enabling & scaling power rails, clocks and bandwidth ourselves. Reuse existing Adreno-common code and modify the deeply-GMU-infused A6XX code to facilitate these GPUs. This involves if-ing out lots of GMU callbacks and introducing a new type of GMU - GMU wrapper (it's the actual name that Qualcomm uses in their downstream kernels). This is essentially a register region which is convenient to model as a device. We'll use it for managing the GDSCs. The register layout matches the actual GMU_CX/GX regions on the "real GMU" devices and lets us reuse quite a bit of gmu_read/write/rmw calls.

2023-06-16nouveau: fix client work fence deletion raceDave Airlie
This seems to have existed for ever but is now more apparant after commit 9bff18d13473 ("drm/ttm: use per BO cleanup workers") My analysis: two threads are running, one in the irq signalling the fence, in dma_fence_signal_timestamp_locked, it has done the DMA_FENCE_FLAG_SIGNALLED_BIT setting, but hasn't yet reached the callbacks. The second thread in nouveau_cli_work_ready, where it sees the fence is signalled, so then puts the fence, cleanups the object and frees the work item, which contains the callback. Thread one goes again and tries to call the callback and causes the use-after-free. Proposed fix: lock the fence signalled check in nouveau_cli_work_ready, so either the callbacks are done or the memory is freed.

2023-06-15drm/dp_mst: Clear MSG_RDY flag before sending new messageWayne Lin
[Why] The sequence for collecting down_reply from source perspective should be: Request_n->repeat (get partial reply of Request_n->clear message ready flag to ack DPRX that the message is received) till all partial replies for Request_n are received->new Request_n+1. Now there is chance that drm_dp_mst_hpd_irq() will fire new down request in the tx queue when the down reply is incomplete. Source is restricted to generate interveleaved message transactions so we should avoid it. Also, while assembling partial reply packets, reading out DPCD DOWN_REP Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be wrapped up as a complete operation for reading out a reply packet. Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might be risky. e.g. If the reply of the new request has overwritten the DPRX DOWN_REP Sideband MSG buffer before source writing one to clear DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply for the new request. Should handle the up request in the same way. [How] Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might trigger drm_dp_mst_kick_tx() only when there is no on going message transaction. Changes since v1: * Reworked on review comments received -> Adjust the fix to let driver explicitly kick off new down request when mst irq event is handled and acked -> Adjust the commit message Changes since v2: * Adjust the commit message * Adjust the naming of the divided 2 functions and add a new input parameter "ack". * Adjust code flow as per review comments. Changes since v3: * Update the function description of drm_dp_mst_hpd_irq_handle_event Changes since v4: * Change ack of drm_dp_mst_hpd_irq_handle_event() to be an array align the size of esi[] Signed-off-by: Wayne Lin <Wayne.Lin@amd.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2023-06-15drm/amdgpu: Increase hmm range get pages timeoutPhilip Yang
If hmm_range_fault returns -EBUSY, we should call hmm_range_fault again to validate the remaining pages. On one system with NUMA auto balancing enabled, hmm_range_fault takes 6 seconds for 1GB range because CPU migrate the range one page at a time. To be safe, increase timeout value to 1 second for 128MB range.
