[REGRESSION] boot fails for EFI boot stub loaded by u-boot

by Ben Schneider

Hi Ard, I have an ESPRESSObin Ultra (aarch64) that uses U-Boot as its bootloader. It shipped from the manufacturer with with v5.10, and I've been trying to upgrade. U-Boot supports booting Image directly via EFI (https://u-boot.readthedocs.io/en/latest/usage/cmd/bootefi.html), and I have been using it that way to successfully boot the system up to and including v6.0.19. However, v6.1 and v6.5 kernels fail to boot. When booting successfully, the following messages are displayed: EFI stub: Booting Linux Kernel...EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: Using DTB from configuration table EFI stub: ERROR: Failed to install memreserve config table! EFI stub: Exiting boot services... [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] I suspect many of the above error messages are simply attributable to using U-Boot to load an EFI stub and can be safely ignored given that the system boots and runs fine. When boot fails (v6.5), the following messages are displayed: EFI stub: Booting Linux Kernel... EFI stub: ERROR: FIRMWARE BUG: efi_loaded_image_t::image_base has bogus value EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: ERROR: Failed to install memreserve config table! EFI stub: Using DTB from configuration table EFI stub: Exiting boot services... EFI stub: ERROR: Unable to construct new device tree. EFI stub: ERROR: Failed to update FDT and exit boot services In case it's relevant, the device tree for this device is arch/arm64/boot/marvell/armada-3720-espressobin-ultra.dts Hopefully I've reported this in the correct place or that the information provided is sufficient to get it where it needs to be. Let me know if there is additional information I can provide. I am also able to use the device to test. Sincerely, Ben Schneider #regzbot introduced v6.0..v6.1

[PATCH] x86/cpu/intel: Detect TME keyid bits before setting MTRR mask registers

by Paolo Bonzini

MKTME repurposes the high bit of physical address to key id for encryption key and, even though MAXPHYADDR in CPUID[0x80000008] remains the same, the valid bits in the MTRR mask register are based on the reduced number of physical address bits. detect_tme() in arch/x86/kernel/cpu/intel.c detects TME and subtracts it from the total usable physical bits, but it is called too late. Move the call to early_init_intel() so that it is called in setup_arch(), before MTRRs are setup. This fixes boot on some TDX-enabled systems which until now only worked with "disable_mtrr_cleanup". Without the patch, the values written to the MTRRs mask registers were 52-bit wide (e.g. 0x000fffff_80000800) and the writes failed; with the patch, the values are 46-bit wide, which matches the reduced MAXPHYADDR that is shown in /proc/cpuinfo.

[PATCH v2 0/3] HID: bpf: couple of upstream fixes

by Benjamin Tissoires

Hi, This is the v2 of this series of HID-BPF fixes. I have forgotten to include a Fixes tag in the first patch and got a review from Andrii on patch 2. And this first patch made me realize that something was fishy in the refcount of the hid devices. I was not crashing the system even if I accessed the struct hid_device after hid_destroy_device() was called, which was suspicious to say the least. So after some debugging I found the culprit and realized that I had a pretty nice memleak as soon as one HID-BPF program was attached to a HID device. The good thing though is that this ref count prevents a crash in case a HID-BPF program attempts to access a removed HID device when hid_bpf_allocate_context() has been called but not yet released. Anyway, for reference, the cover letter of v1: --- Hi, these are a couple of fixes for hid-bpf. The first one should probably go in ASAP, after the reviews, and the second one is nice to have and doesn't hurt much. Thanks Dan for finding out the issue with bpf_prog_get() Cheers, Benjamin To: Jiri Kosina <jikos(a)kernel.org> To: Benjamin Tissoires <benjamin.tissoires(a)redhat.com> To: Dan Carpenter <dan.carpenter(a)linaro.org> To: Daniel Borkmann <daniel(a)iogearbox.net> To: Andrii Nakryiko <andrii.nakryiko(a)gmail.com> Cc: <linux-input(a)vger.kernel.org> Cc: <linux-kernel(a)vger.kernel.org> Cc: <bpf(a)vger.kernel.org> Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Changes in v2: - add Fixes tags - handled Andrii review (use of __bpf_kfunc_start/end_defs()) - new patch to fetch ref counting of struct hid_device - Link to v1: https://lore.kernel.org/r/20240123-b4-hid-bpf-fixes-v1-0-aa1fac734377@kerne… --- Benjamin Tissoires (3): HID: bpf: remove double fdget() HID: bpf: actually free hdev memory after attaching a HID-BPF program HID: bpf: use __bpf_kfunc instead of noinline drivers/hid/bpf/hid_bpf_dispatch.c | 101 ++++++++++++++++++++++++++---------- drivers/hid/bpf/hid_bpf_dispatch.h | 4 +- drivers/hid/bpf/hid_bpf_jmp_table.c | 39 +++++++------- include/linux/hid_bpf.h | 11 ---- 4 files changed, 95 insertions(+), 60 deletions(-) --- base-commit: fef018d8199661962b5fc0f0d1501caa54b2b533 change-id: 20240123-b4-hid-bpf-fixes-662908fe2234 Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>

[PATCH] irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems

by Marc Zyngier

While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost. As a result, systems such as HIP07 lose their GICv4 functionnality, and some other may even fail to boot, unless they are configured to boot with DT. Move the enabling of quirks into its_probe_one(), making it common to all firmware implementations.
