2025-02-05ice: simplify VF MSI-X managingMichal Swiatkowski4-173/+79
After implementing pf->msix.max field, base vector for other use cases (like VFs) can be fixed. This simplify code when changing MSI-X amount on particular VF, because there is no need to move a base vector. A fixed base vector allows to reserve vectors from the beginning instead of from the end, which is also simpler in code. Store total and rest value in the same struct as max and min for PF. Move tracking vectors from ice_sriov.c to ice_irq.c as it can be also use for other none PF use cases (SIOV).

2025-02-05ice: treat dyn_allowed only as suggestionMichal Swiatkowski2-12/+15
It can be needed to have some MSI-X allocated as static and rest as dynamic. For example on PF VSI. We want to always have minimum one MSI-X on it, because of that it is allocated as a static one, rest can be dynamic if it is supported. Change the ice_get_irq_res() to allow using static entries if they are free even if caller wants dynamic one. Adjust limit values to the new approach. Min and max in limit means the values that are valid, so decrease max and num_static by one. Set vsi::irq_dyn_alloc if dynamic allocation is supported.

With dynamic approach to alloc MSI-X there is no sense to statically split MSI-X between PF features. Splitting was also calculating needed MSI-X.

xen_hypercall_hvm(), which is used when running as a Xen PVH guest at most only once during early boot, is clobbering %rbx. Depending on whether the caller relies on %rbx to be preserved across the call or not, this clobbering might result in an early crash of the system.

2025-02-05kbuild: keep symbols for symbol_get() even with CONFIG_TRIM_UNUSED_KSYMSMasahiro Yamada5-1/+47
Linus observed that the symbol_request(utf8_data_table) call fails when CONFIG_UNICODE=y and CONFIG_TRIM_UNUSED_KSYMS=y. symbol_get() relies on the symbol data being present in the ksymtab for symbol lookups. However, EXPORT_SYMBOL_GPL(utf8_data_table) is dropped due to CONFIG_TRIM_UNUSED_KSYMS, as no module references it in this case. Probably, this has been broken since commit dbacb0ef670d ("kconfig option for TRIM_UNUSED_KSYMS"). This commit addresses the issue by leveraging modpost. Symbol names passed to symbol_get() are recorded in the special .no_trim_symbol section, which is then parsed by modpost to forcibly keep such symbols. The .no_trim_symbol section is discarded by the linker scripts, so there is no impact on the size of the final vmlinux or modules. This commit cannot resolve the issue for direct calls to __symbol_get() because the symbol name is not known at compile-time. Although symbol_get() may eventually be deprecated, this workaround should be good enough meanwhile.

2025-02-05scripts/Makefile.extrawarn: Do not show clang's non-kprintf warnings at W=1Nathan Chancellor1-5/+5
Clang's -Wformat-overflow and -Wformat-truncation have chosen to check '%p' unlike GCC but it does not know about the kernel's pointer extensions in lib/vsprintf.c, so the developers split that part of the warning out for the kernel to disable because there will always be false positives. Commit 908dd508276d ("kbuild: enable -Wformat-truncation on clang") did disabled these warnings but only in a block that would be called when W=1 was not passed, so they would appear with W=1. Move the disabling of the non-kprintf warnings to a block that always runs so that they are never seen, regardless of warning level.

2025-02-05net: atlantic: fix warning during hot unplugJacob Moroni1-1/+3
Firmware deinitialization performs MMIO accesses which are not necessary if the device has already been removed. In some cases, these accesses happen via readx_poll_timeout_atomic which ends up timing out, resulting in a warning at hw_atl2_utils_fw.c:112: [ 104.595913] Call Trace: [ 104.595915] <TASK> [ 104.595918] ? show_regs+0x6c/0x80 [ 104.595923] ? __warn+0x8d/0x150 [ 104.595925] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595934] ? report_bug+0x182/0x1b0 [ 104.595938] ? handle_bug+0x6e/0xb0 [ 104.595940] ? exc_invalid_op+0x18/0x80 [ 104.595942] ? asm_exc_invalid_op+0x1b/0x20 [ 104.595944] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595952] ? aq_a2_fw_deinit+0xcf/0xe0 [atlantic] [ 104.595959] aq_nic_deinit.part.0+0xbd/0xf0 [atlantic] [ 104.595964] aq_nic_deinit+0x17/0x30 [atlantic] [ 104.595970] aq_ndev_close+0x2b/0x40 [atlantic] [ 104.595975] __dev_close_many+0xad/0x160 [ 104.595978] dev_close_many+0x99/0x170 [ 104.595979] unregister_netdevice_many_notify+0x18b/0xb20 [ 104.595981] ? __call_rcu_common+0xcd/0x700 [ 104.595984] unregister_netdevice_queue+0xc6/0x110 [ 104.595986] unregister_netdev+0x1c/0x30 [ 104.595988] aq_pci_remove+0xb1/0xc0 [atlantic] Fix this by skipping firmware deinitialization altogether if the PCI device is no longer present.

2025-02-04gpio: pca953x: Improve interrupt supportMark Tomlinson1-19/+0
The GPIO drivers with latch interrupt support (typically types starting with PCAL) have interrupt status registers to determine which particular inputs have caused an interrupt. Unfortunately there is no atomic operation to read these registers and clear the interrupt. Clearing the interrupt is done by reading the input registers. The code was reading the interrupt status registers, and then reading the input registers. If an input changed between these two events it was lost. The solution in this patch is to revert to the non-latch version of code, i.e. remembering the previous input status, and looking for the changes. This system results in no more I2C transfers, so is no slower. The latch property of the device still means interrupts will still be noticed if the input changes back to its initial state.

2025-02-04accel/amdxdna: Add MODULE_FIRMWARE() declarationsMario Limonciello1-0/+5
Initramfs building tools such as dracut will look for a MODULE_FIRMWARE() declaration to determine which firmware to include in the initramfs when a driver is included in the initramfs. As amdxdna doesn't declare any firmware this causes the driver to fail to load with -ENOENT when in the initramfs. Add the missing declaration for possible firmware.

2025-02-04drm/i915/dp: Iterate DSC BPP from high to low on all platformsJani Nikula1-4/+3
Commit 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") tries to find the best compressed bpp for the link. However, it iterates from max to min bpp on display 13+, and from min to max on other platforms. This presumably leads to minimum compressed bpp always being chosen on display 11-12. Iterate from high to low on all platforms to actually use the best possible compressed bpp. Fixes: 1c56e9a39833 ("drm/i915/dp: Get optimal link config to have best compressed bpp") Cc: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Cc: Imre Deak <imre.deak@intel.com> Cc: <stable@vger.kernel.org> # v6.7+ Reviewed-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ankit Nautiyal <ankit.k.nautiyal@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/3bba67923cbcd13a59d26ef5fa4bb042b13c8a9b.1738327620.git.jani.nikula@intel.com (cherry picked from commit 56b0337d429356c3b9ecc36a03023c8cc856b196) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
