riscv: Optimize bitops with Zbb extension
This patch leverages the alternative mechanism to dynamically optimize bitops (including __ffs, __fls, ffs, fls) with Zbb instructions. When Zbb ext is not supported by the runtime CPU, legacy implementation is used. If Zbb is supported, then the optimized variants will be selected via alternative patching. The legacy bitops support is taken from the generic C implementation as fallback. If the parameter is a build-time constant, we leverage compiler builtin to calculate the result directly, this approach is inspired by x86 bitops implementation. EFI stub runs before the kernel, so alternative mechanism should not be used there, this patch introduces a macro NO_ALTERNATIVE for this purpose.

The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmVC40IACgkQYKtH/8kJ Uidhmw/9EX+aWSXGoObJ3fngaNSMw+PmrEuP8qEKBHxfKHcCdX3hc451Oh4GlhaQ tru91pPwgNvN2/rfoKusxT+V4PemGIzfNni/04rp+P0kvmdw5otQ2yNhsQNsfVmq XGWvkxF4P2GO6bkjjfR/1dDq7GtlyXtwwPDKeLbYb6TnJOZjtx+EAN27kkfSn1Ms R4Sa3zJ+DfHUmHL5S9g+7UD/CZ5GfKNmIskI4Mz5GsfoUz/0iiU+Bge/9sdcdSJQ kmbLy5YnVzfooLZ3TQmBFsO3iAMWb0s/mDdtyhqhTVmTUshLolkPYyKnPFvdupyv shXcpEST2XJNeaDRnL2K4zSCdxdbnCZHDpjfl9wfioBg7I8NfhXKpf1jYZHH1de4 LXq8ndEFEOVQw/zSpYWfQq1sux8Jiqr+UK/ukbVeFWiGGIUs91gEWtPAf8T0AZo9 ujkJvaWGl98O1g5wmBu0/dAR6QcFJMDfVwbmlIFpU8O+MEaz6X8mM+O5/T0IyTcD eMbAUjj4uYcU7ihKzHEv/0SS9Of38kzff67CLN5k8wOP/9NlaGZ78o1bVle9b52A BdhrsAefFiWHp1jT6Y9Rg4HOO/TguQ9e6EWSKOYFulsiLH9LEFaB9RwZLeLytV0W vlAgY9rUW77g1OJcb7DoNv33nRFuxsKqsnz3DEIXtgozo9CzbYI= =H1vH -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull ia64 removal and asm-generic updates from Arnd Bergmann: - The ia64 architecture gets its well-earned retirement as planned, now that there is one last (mostly) working release that will be maintained as an LTS kernel. - The architecture specific system call tables are updated for the added map_shadow_stack() syscall and to remove references to the long-gone sys_lookup_dcookie() syscall. * tag 'asm-generic-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: hexagon: Remove unusable symbols from the ptrace.h uapi asm-generic: Fix spelling of architecture arch: Reserve map_shadow_stack() syscall number for all architectures syscalls: Cleanup references to sys_lookup_dcookie() Documentation: Drop or replace remaining mentions of IA64 lib/raid6: Drop IA64 support Documentation: Drop IA64 from feature descriptions kernel: Drop IA64 support from sig_fault handlers arch: Remove Itanium (IA-64) architecture |

SoC driver updates for 6.7
The highlights for the driver support this time are
- Qualcomm platforms gain support for the Qualcomm Secure Execution
Environment firmware interface to access EFI variables on certain
devices, and new features for multiple platform and firmware drivers.
- Arm FF-A firmware support gains support for v1.1 specification features,
in particular notification and memory transaction descriptor changes.
- SCMI firmware support now support v3.2 features for clock and DVFS
configuration and a new transport for Qualcomm platforms.
- Minor cleanups and bugfixes are added to pretty much all the active
platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
In particular, this contains portions of the treewide conversion to
use __counted_by annotations and the device_get_match_data helper.

ARM: SoC fixes for 6.7, part 3
A couple of platforms have some last-minute fixes for 6.7, in particular
- riscv gets some fixes for noncoherent DMA on the renesas and thead
platforms and dts fix for SPI on the visionfive 2 board
- Qualcomm Snapdragon gets three dts fixes to address board specific
regressions on the pmic and gpio nodes
- Rockchip platforms get multiple dts fixes to address issues on
the recent rk3399 platform as well as the older rk3128 platform
that apparently regressed a while ago.
- TI OMAP gets some trivial code and dts fixes and a regression fix
for the omap1 ams-delta modem
- NXP i.MX firmware has one fix for a use-after-free but in its
error handling.

More Qualcomm driver updates for v6.7
The Qualcomm SMC an QSEECOM drivers are moved into a "qcom" subdirectory, to declutter the base directory. Missing include guards are added to the qseecom header file. Unneded extern specifiers are removed from the scm call wrappers. __counted_by is added to the apr_rx_buf structure, in the APR driver. Lastly in the pmic_glink driver the pmic_glink drm_bridge type is corrected to DisplayPort, over the incorrect "USB" value. The return values are added to error prints for the various typec set() calls. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmU5desVHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3FEY4QAL9q2iDnHbo908AiD781vvoJ0t6H FJDFRwDQXv/JaLHKc6kXt2JQZZGAkTFqPiiu06DWVfgk7oXwBHmdsaq+nXqJGTfx 3vR6/1TBzMgv3eT4zzPPZF/0E0mttLczZSd5z7Vg4oe1RSVGpaOe6icmxxLNiG0J LZN6o18rsfcl0TrCt2nR95BkkKINO7mfqz5iJWYTS8K8SM+APjrAoYOlWfE9VfBo FFni1UIJAVGL3qMECZ2ntUEVIUQZJu1vhL50/S5tRROPR1PCDJ1i2SThD209I3M2 cmbVST3boIgqC9lv36NsZzDNg1kYCR7lT9SVOxSZUjZvAxY5Kz+t7HJyTvRcnTA7 INw02mk2lWPvvTYKpwo0d0JMfTa7ReYC5Im4Nijk5hNExwu4zomWDpcCtrb6I/T8 Eqrr4p/2WVGZ5OvMEcZzUULLyenZ9vS3ABKmjmbI2oj4CuVukJPFy0LSLgy1ZgAh RKAplCRp0HkxL+M9qsCB1HhQksS6y7sjrx7amXl+mn2+/7AVa61QfsuDg2Qc/k5r SHhfk51jXPI3modH96ieThOHmcoK+vHUFPgwGbgPkiHdNaXXbMkFgYdD1XQ6WLJc ZYLDhpWrSzB6NkrczCogXbJflla6knZ1dz5zRQVeBO4x4dRq5O8O3VPQ3k18/Aj4 w7NtiweoKMx3RuBp =dVO+ -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmU5gXYACgkQYKtH/8kJ Uic6/xAA2ZU8EPNMnsFe7kXEmBo9/OTHpFD7A7snaF2tjZ3NgP/vGR8D/nxCb8g3 WbgBwHAvR1QfOGc1ACC0j20t+c0GvcsIoLn296madHHZtO42j46O0OQW7uC7vm7u Bu8QSyjUl9DncZOUFD64Q9yTZhi+857iJEvras2qpyiaXFdmoq0FKWzOf2y79DZl GwrIVOSWM8rA739JU4LEW7Xe21deTjqOpdTv9yLu+levOQaUwTs/waCTgTdDiLaG 3C7ptpkWTeqlfKUKMXWzPSmggnRDRnRJNOyQMzpq8ftalbZYv34ScNBNtuevahcu dmB8iFEBSZGdvCAMB0rGEopENW7lfoJXqxyTalS1S8yPjy3cSsHq3pkkU9R84L8Y 0MoI0IARwYoZvzEXYHEMi+BstGBQglXoCgBYaBlvhjJ1+kgtFfiW+xTPd1DghkyM /NiV6/4a87ccbT05Je0qbZdRBptu4EGSwcFeUHEkskfEWtps6RZCqWWnPSQoUgQC Lu6lOvle+rSrQ5hNS+RlX5NIdfbKJ0x6HamZVfeDXzuSnh7023dmXUqib7xpCMa7 PQAIhsXDesT8b2gP04+JX2hphvQ/il2BowCOw5j9Xg2XQSs5Alf++sfY9DS32oYk pnqMT/6UISVbwI4MVgNtwFujW1+zF+RwyMXurKSAi2hTirdgHuw= =PxVV -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-6.7-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers More Qualcomm driver updates for v6.7 The Qualcomm SMC an QSEECOM drivers are moved into a "qcom" subdirectory, to declutter the base directory.

efi/unaccepted: Fix soft lockups caused by parallel memory acceptance
Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.
The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.
To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.
A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.
Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.
Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.
The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

Qualcomm driver updates for v6.7
This introduces partial support for the Qualcomm Secure Execution Environment SCM interface, and uses this to implement EFI variable access on the Windows On Snapdragon devices (for now). The 32/64-bit calling convention detector of the SCM interface is updated to not choose 64-bit convention when Linux is 32-bit. The "extern" specifier is dropped from the interface include file. The LLCC driver gains support for carrying configuration for multiple different system/DDR configurations for a given platform, and selecting between them. Support for Q[DR]U1000 is added to the driver. All exported symbols are transitioned to EXPORT_SYMBOL_GPL(). The platform_drivers in the Qualcomm SoC are transitioned to the void-returning remove_new implementation. The rmtfs memory driver gains support for leaving guard pages around the used area, to avoid issues if the allocation happens to be placed adjacent to another protected memory region.

efi: move screen_info into efi init code
After the vga console no longer relies on global screen_info, there are only two remaining use cases: - on the x86 architecture, it is used for multiple boot methods (bzImage, EFI, Xen, kexec) to commucate the initial VGA or framebuffer settings to a number of device drivers. - on other architectures, it is only used as part of the EFI stub, and only for the three sysfb framebuffers (simpledrm, simplefb, efifb). Remove the duplicate data structure definitions by moving it into the efi-init.c file that sets it up initially for the EFI case, leaving x86 as an exception that retains its own definition for non-EFI boots. The added #ifdefs here are optional, I added them to further limit the reach of screen_info to configurations that have at least one of the users enabled.

vgacon: clean up global screen_info instances
To prepare for completely separating the VGA console screen_info from the one used in EFI/sysfb, rename the vgacon instances and make them local as much as possible. ia64 and arm both have confurations with vgacon and efi, but the contents never overlaps because ia64 has no EFI framebuffer, and arm only has vga console on legacy platforms without EFI. Renaming these is required before the EFI screen_info can be moved into drivers/firmware. The ia64 vga console is actually registered in two places from setup_arch(), but one of them is wrong, so drop the one in pcdp.c and fix the one in setup.c to use the correct conditional. x86 has to keep them together, as the boot protocol is used to switch between VGA text console and framebuffer through the screen_info data.

Arm FF-A updates for v6.7
The main addition is the initial support for the notifications and memory transaction descriptor changes added in FF-A v1.1 specification. The notification mechanism enables a requester/sender endpoint to notify a service provider/receiver endpoint about an event with non-blocking semantics. A notification is akin to the doorbell between two endpoints in a communication protocol that is based upon the doorbell/mailbox mechanism. The framework is responsible for the delivery of the notification from the ender to the receiver without blocking the sender. The receiver endpoint relies on the OS scheduler for allocation of CPU cycles to handle a notification. OS is referred as the receiver’s scheduler in the context of notifications. The framework is responsible for informing the receiver’s scheduler that the receiver must be run since it has a pending notification. The series also includes support for the new format of memory transaction descriptors introduced in v1.1 specification. Apart from the main additions, it includes minor fixes to re-enable FF-A drivers usage of 32bit mode of messaging and kernel warning due to the missing assignment of IDR allocation ID to the FFA device. It also adds emitting 'modalias' to the base attribute of FF-A devices. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmUlJuUACgkQAEG6vDF+ 4pinPRAAzLFtehLNhpC2BsEbvdJo/bSeGl1OAricml3gyU45W7AamAPuplA9E871 GxXMYbH5+mnqz5cHaYBb8KGm5dRENrtKgrwMITg3jOlqdz9HWy2MLgbSmvqbXNsU 5O8iZDvFOTCMLSEI6gWnaiKRpAzDSFu0/FH86xv+9+pbjmjL3iDjFlbxbGLFYk+L gqHLdx4iW6aD6geC2n8oDO6UWCNLaHpXaJSAE6pfh/7pkuKMWYjVwivKxrMA9Saw WjoyBdjUgir9w6qJauR94MGMnbPTd378MzBrEWMo04I2ubLCVwiPVDEEu7jZGrBV 2n5DD8/0fSak9KEEozRKnj9umhmvHN9Of72qBLNZ0K4zmq8Fs00woXIlnUNH0dcZ qZN/ZEDXpD51OsgMH+ojojaqFEcFynEQIQjibiv1Ju16F+1PIABCyODgb58fIa71 WvRUXVttkml6boY7KqGIDRiSRfEIZfoWqKucFpEbRwCXLLqc2VJ4UYUiYB1B3fD1 g3ZuQXhurwfLG7SwrKK4KWFLHTSNj4IuixeqsAM+PYyTE5iquP3xpqYgbb99n9VT SWCyQdw0e+DyAhzmx0ZZZtCO2f54JQY852jHSkQFQsRNcK+h2exYxjIE7NfgfIGG H1NvJjumunOZEOZr+Wwz74wDJDMoLvMJTGr4ovIkNn/xb+4lcHU= =bHXY -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmUto10ACgkQYKtH/8kJ UidIlw//e0ZkLIffq0d9svTie4NHxxb8AEu8sqnxr1HcinpCfa2Cwi6utt+y5XXc Ti7T7Jj/BKnwTfNXw6REvKplBhMGMQFkKcrX7lSnDpPhzCj8Ls0j78ac52KfmVpi HmzRchsdKtKBYKZOBA+gnBABu38O9QvuteDKJXx8vzowztYJpHc/UmE5qYHwVWDT kKqNzFo34zvLS/ephZZFV113ji3foQiOFCWtx408nfcUvW/g8H3xRp6njPlmP0Ue PhFbR3qsEV/nLTafypACsxSappuHngtInXZA2cpA6LKc0oS426rTvY6i167amOq4 ktcqmVdD6mbNEApTsB5O32TK+AI2rPvCh6OCS0x0M6+yWhZVGjZXZgzr1Ma3uphz dD3HcXYEaMHJQVAu8npVo5x3UEApOts+SX7QY4IlekzCzr1guhnWKnmxTS8jYx2Z HzwJatmvb+ENzbZHX2R1Y53keue/oq0AkYva0gNVK6F7ELjowDmV0l02qm5G0aBC 3Pa1KEYpb34qagwknzFjGubBrJcPX/sdzt1KWUoCLDbveb+HCaPKlGipOs3PjMLy s/IeGH7LED3XbfxDpsRuzkwgtKzuvmdaWfgccx56rPjMlh763fvS16DB2PUiJ4FP qv7fu98hvVG2Z2eFVHib3FT6isw4NVmsXRzc6uW54nVKj2pQmRY= =QaJo -----END PGP SIGNATURE----- Merge tag 'ffa-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A updates for v6.7 The main addition is the initial support for the notifications and memory transaction descriptor changes added in FF-A v1.1 specification.

Arm SCMI updates for v6.7
Main additions this time include:
1. SCMI v3.2 clock configuration support:
This helps to retrieve the enabled state of a clock as well as allow
to set OEM specific clock configurations.
2. Support for generic performance scaling(DVFS):
The current SCMI DVFS support is limited to the CPUs in the kernel.
This extension enables it to used for all kind of devices and not
only for the CPUs. It updates the SCMI cpufreq to utilize the power
domain bindings. It also adds a more generic SCMI performance domain
based on the genpd framework that as be used for all the non-CPU
devices.
3. Extend the generic performance scaling(DVFS) support for firmware
driver OPPs:
Consumer drivers for devices that are attached to the SCMI performance
domain can't make use of the current OPP library to scale performance
as the OPPs are firmware driven and often obtained from the firmware
rather than the device tree. These changes extend the generic OPP
and genpd PM domain frameworks to identify and utilise these firmware
driven OPPs.

Merge tag 'scmi-updates-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers
Arm SCMI updates for v6.7
Main additions this time include:
1. SCMI v3.2 clock configuration support:
This helps to retrieve the enabled state of a clock as well as allow
to set OEM specific clock configurations.
2. Support for generic performance scaling(DVFS):
The current SCMI DVFS support is limited to the CPUs in the kernel.
This extension enables it to used for all kind of devices and not
only for the CPUs. It updates the SCMI cpufreq to utilize the power
domain bindings. It also adds a more generic SCMI performance domain
based on the genpd framework that as be used for all the non-CPU
devices.
3. Extend the generic performance scaling(DVFS) support for firmware
driver OPPs:
Consumer drivers for devices that are attached to the SCMI performance
domain can't make use of the current OPP library to scale performance
as the OPPs are firmware driven and often obtained from the firmware
rather than the device tree. These changes extend the generic OPP
and genpd PM domain frameworks to identify and utilise these firmware
driven OPPs.
4. SCMI v3.2 clock parent support:
This enables the support for discovering and changing parent clocks
and extending the SCMI clk driver to use the same.
5. Qualcom SMC/HVC transport support:
The Qualcomm virtual platforms require capability id in the hypervisor
call to identify which doorbell to assert when supporting multiple
SMC/HVC based SCMI transport channels. Extra parameter is added to
support the same and the same is obtained at the fixed address in the
shared memory which is initialised by the firmware.
6. Move the existing SCMI power domain driver under drivers/pmdomain
Apart from the above main changes, it also include couple of minor fixes
and cosmetic reworks.

firmware: tegra: Add suspend hook and reset BPMP IPC early on resume
Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.
One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.
The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

efi: fix memory leak in krealloc failure handling
In the previous code, there was a memory leak issue where the previously allocated memory was not freed upon a failed krealloc operation. This patch addresses the problem by releasing the old memory before setting the pointer to NULL in case of a krealloc failure. This ensures that memory is properly managed and avoids potential memory leaks. Signed-off-by: Kuan-Wei Chiu <visitorckw@gmail.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |

x86/efistub: Don't try to print after ExitBootService()
setup_e820() is executed after UEFI's ExitBootService has been called. This causes the firmware to throw an exception because the Console IO protocol is supposed to work only during boot service environment. As per UEFI 2.9, section 12.1: "This protocol is used to handle input and output of text-based information intended for the system user during the operation of code in the boot services environment." So drop the diagnostic warning from this function. We might add back a warning that is issued later when initializing the kernel itself.

firmware: arm_scmi: Add qcom smc/hvc transport support
This change adds the support for SCMI message exchange on Qualcomm virtual platforms. The hypervisor associates an object-id also known as capability-id with each smc/hvc doorbell object. The capability-id is used to identify the doorbell from the VM's capability namespace, similar to a file-descriptor. The hypervisor, in addition to the function-id, expects the capability-id to be passed in x1 register when SMC/HVC call is invoked. The capability-id is allocated by the hypervisor on bootup and is stored in the shmem region by the firmware before starting Linux.

Also update ffa_mem_desc_offset() accessor to handle both old and new formats of memory transaction descriptors. The updated ffa_mem_region structure aligns with new format in v1.1 and hence the driver/user must take care not to use members beyond and including ep_mem_offset when using the old format.

The computation of endpoint memory access descriptor's composite memory region descriptor offset is using COMPOSITE_CONSTITUENTS_OFFSET which is unnecessary complicated. Composite memory region descriptor always follow the endpoint memory access descriptor array and hence it is computed accordingly. COMPOSITE_CONSTITUENTS_OFFSET is useless and wrong for any input other than endpoint memory access descriptor count. Let us drop the usage of COMPOSITE_CONSTITUENTS_OFFSET to simplify the computation of total transmit and fragment length in the memory transactions.
