8998eedda2 drm/fbdev-dma: Support struct drm_driver.fbdev_probe
Rework fbdev probing to support fbdev_probe in struct drm_driver
and reimplement the old fb_probe callback on top of it. Provide an
initializer macro for struct drm_driver that sets the callback
according to the kernel configuration.

This change allows the common fbdev client to run on top of DMA-
based DRM drivers.

d07fdf9225 drm: Add client-agnostic setup helper
DRM may support multiple in-kernel clients that run as soon as a DRM
driver has been registered. To select the client(s) in a single place,
introduce drm_client_setup().

Drivers that call the new helper automatically instantiate the kernel's
configured default clients. Only fbdev emulation is currently supported.
Later versions can add support for DRM-based logging, a boot logo or even
a console.

Some drivers handle the color mode for clients internally. Provide the
helper drm_client_setup_with_color_mode() for them.

Using the new interface requires the driver to select
DRM_CLIENT_SELECTION in its Kconfig. For now this only enables the
client-setup helpers if the fbdev client has been configured by the
user. A future patchset will further modularize client support and
rework DRM_CLIENT_SELECTION to select the correct dependencies for
all its clients.

v5:
- add CONFIG_DRM_CLIENT_SELECTION und DRM_CLIENT_SETUP
v4:
- fix docs for drm_client_setup_with_fourcc() (Geert)
v3:
- fix build error
v2:
- add drm_client_setup_with_fourcc() (Laurent)
- push default-format handling into actual clients

5d08c44e47 drm/fbdev: Add memory-agnostic fbdev client
Add an fbdev client that can work with any memory manager. The
client implementation is the same as existing code in fbdev-dma or
fbdev-shmem.

Provide struct drm_driver.fbdev_probe for the new client to allocate
the surface GEM buffer. The new callback replaces fb_probe of struct
drm_fb_helper_funcs, which does the same.

To use the new client, DRM drivers set fbdev_probe in their struct
drm_driver instance and call drm_fbdev_client_setup(). Probing and
creating the fbdev surface buffer is now independent from the other
operations in struct drm_fb_helper. For the pixel format, the fbdev
client either uses a specified format, the value in preferred_depth
or 32-bit RGB.

v2:
- test for struct drm_fb_helper.funcs for NULL (Sui)
- respect struct drm_mode_config.preferred_depth for default format

eb1f4adf91 drm/fbdev-helper: Move color-mode lookup into 4CC format helper
The color mode as specified on the kernel command line gives the user's
preferred color depth and number of bits per pixel. Move the
color-mode-to-format conversion from fbdev helpers into a 4CC helper,
so that it can be shared among DRM clients.

v2:

f70000ef23 drm/panthor: Add DEV_QUERY_GROUP_PRIORITIES_INFO dev query
Expose allowed group priorities with a new device query.

This new uAPI will be used in Mesa to properly report what priorities a
user can use for EGL_IMG_context_priority.

Since this extends the uAPI and because userland needs a way to
advertise priorities accordingly, this also bumps the driver minor
version.

v2:
- Remove drm_panthor_group_allow_priority_flags definition
- Document that allowed_mask is a bitmask of drm_panthor_group_priority

v3:
- Use BIT macro in panthor_query_group_priorities_info
- Add r-b from Steven Price and Boris Brezillon

b2ef808786 drm/sched: add optional errno to drm_sched_start()
The current implementation of drm_sched_start uses a hardcoded
-ECANCELED to dispose of a job when the parent/hw fence is NULL.
This results in drm_sched_job_done being called with -ECANCELED for
each job with a NULL parent in the pending list, making it difficult
to distinguish between recovery methods, whether a queue reset or a
full GPU reset was used.

To improve this, we first try a soft recovery for timeout jobs and
use the error code -ENODATA. If soft recovery fails, we proceed with
a queue reset, where the error code remains -ENODATA for the job.
Finally, for a full GPU reset, we use error codes -ECANCELED or
-ETIME. This patch adds an error code parameter to drm_sched_start,
allowing us to differentiate between queue reset and GPU reset
failures. This enables user mode and test applications to validate
the expected correctness of the requested operation. After a
successful queue reset, the only way to continue normal operation is
to call drm_sched_job_done with the specific error code -ENODATA.

v1: Initial implementation by Jesse utilized amdgpu_device_lock_reset_domain
    and amdgpu_device_unlock_reset_domain to allow user mode to track
    the queue reset status and distinguish between queue reset and
    GPU reset.
v2: Christian suggested using the error codes -ENODATA for queue reset
    and -ECANCELED or -ETIME for GPU reset, returned to
    amdgpu_cs_wait_ioctl.
v3: To meet the requirements, we introduce a new function
    drm_sched_start_ex with an additional parameter to set
    dma_fence_set_error, allowing us to handle the specific error
    codes appropriately and dispose of bad jobs with the selected
    error code depending on whether it was a queue reset or GPU reset.
v4: Alex suggested using a new name, drm_sched_start_with_recovery_error,
    which more accurately describes the function's purpose.
    Additionally, it was recommended to add documentation details
    about the new method.
v5: Fixed declaration of new function drm_sched_start_with_recovery_error.(Alex)
v6 (chk): rebase on upstream changes, cleanup the commit message,
          drop the new function again and update all callers,
          apply the errno also to scheduler fences with hw fences
v7 (chk): rebased

Expose timestamp information supported by the GPU with a new device

Mali uses an external timer as GPU system time. On ARM, this is wired to

- Added timestamp_offset to drm_panthor_timestamp_info
- Add missing include for arch_timer_get_cntfrq
- Rework commit message

v3:
- Add panthor_gpu_read_64bit_counter
- Change panthor_gpu_read_timestamp to use
  panthor_gpu_read_64bit_counter

v4:
- Fix multiple typos in uAPI documentation
- Mention behavior when the timestamp frequency is unknown
- Use u64 instead of unsigned long long
  for panthor_gpu_read_timestamp
- Apply r-b from Mihail

5f7762042f drm/panthor: Restrict high priorities on group_create
We were allowing any users to create a high priority group without any
permission checks. As a result, this was allowing possible denial of
service.

We now only allow the DRM master or users with the CAP_SYS_NICE
capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM.

As the sole user of that uAPI lives in Mesa and hardcode a value of
MEDIUM [1], this should be safe to do.

Additionally, as those checks are performed at the ioctl level,
panthor_group_create now only check for priority level validity.

593377036e kvm: Note an RCU quiescent state on guest exit
As of today, KVM notes a quiescent state only in guest entry, which is good
as it avoids the guest being interrupted for current RCU operations.

While the guest vcpu runs, it can be interrupted by a timer IRQ that will
check for any RCU operations waiting for this CPU. In case there are any of
such, it invokes rcu_core() in order to sched-out the current thread and
note a quiescent state.

This occasional schedule work will introduce tens of microsseconds of
latency, which is really bad for vcpus running latency-sensitive
applications, such as real-time workloads.

So, note a quiescent state in guest exit, so the interrupted guests is able
to deal with any pending RCU operations before being required to invoke
rcu_core(), and thus avoid the overhead of related scheduler work.

8f62819aaa PCI/pwrctl: Rescan bus on a separate thread
If we trigger the bus rescan from sysfs, we'll try to lock the PCI rescan
mutex recursively and deadlock - the platform device will be populated and
probed on the same thread that handles the sysfs write.

Add a workqueue to the pwrctl code on which we schedule the rescan for
controlled PCI devices. While at it: add a new interface for initializing
the pwrctl context where we'd now assign the parent device address and
initialize the workqueue.

33f339a1ba bpf, net: Fix a potential race in do_sock_getsockopt()
There's a potential race when `cgroup_bpf_enabled(CGROUP_GETSOCKOPT)` is
false during the execution of `BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN`, but
becomes true when `BPF_CGROUP_RUN_PROG_GETSOCKOPT` is called.
This inconsistency can lead to `BPF_CGROUP_RUN_PROG_GETSOCKOPT` receiving
an "-EFAULT" from `__cgroup_bpf_run_filter_getsockopt(max_optlen=0)`.
Scenario shown as below:

           `process A`                      `process B`
           -----------                      ------------
  BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN
                                            enable CGROUP_GETSOCKOPT
  BPF_CGROUP_RUN_PROG_GETSOCKOPT (-EFAULT)

To resolve this, remove the `BPF_CGROUP_GETSOCKOPT_MAX_OPTLEN` macro and
directly uses `copy_from_sockptr` to ensure that `max_optlen` is always
set before `BPF_CGROUP_RUN_PROG_GETSOCKOPT` is invoked.

3a8d97611b drm/panfrost: Add cycle counter job requirement
Extend the uAPI with a new job requirement flag for cycle
counters. This requirement is used by userland to indicate that a job
requires cycle counters or system timestamp to be propagated. (for use
with write value timestamp jobs)

We cannot enable cycle counters unconditionally as this would result in
an increase of GPU power consumption. As a result, they should be left
off unless required by the application.

If a job requires cycle counters or system timestamps propagation, we
must enable cycle counting before issuing a job and disable it right
after the job completes.

Since this extends the uAPI and because userland needs a way to advertise
features like VK_KHR_shader_clock conditionally, we bumps the driver
minor version.

Linus Torvalds
c9f016e72b A set of X86 fixes:
- x2apic_disable() clears x2apic_state and x2apic_mode unconditionally,
     even when the state is X2APIC_ON_LOCKED, which prevents the kernel to
     disable it thereby creating inconsistent state.
 
     Reorder the logic so it actually works correctly
 
   - The XSTATE logic for handling LBR is incorrect as it assumes that
     XSAVES supports LBR when the CPU supports LBR. In fact both conditions
     need to be true. Otherwise the enablement of LBR in the IA32_XSS MSR
     fails and subsequently the machine crashes on the next XRSTORS
     operation because IA32_XSS is not initialized.
 
     Cache the XSTATE support bit during init and make the related functions
     use this cached information and the LBR CPU feature bit to cure this.
 
   - Cure a long standing bug in KASLR
 
     KASLR uses the full address space between PAGE_OFFSET and vaddr_end to
     randomize the starting points of the direct map, vmalloc and vmemmap
     regions.  It thereby limits the size of the direct map by using the
     installed memory size plus an extra configurable margin for hot-plug
     memory.  This limitation is done to gain more randomization space
     because otherwise only the holes between the direct map, vmalloc,
     vmemmap and vaddr_end would be usable for randomizing.
 
     The limited direct map size is not exposed to the rest of the kernel, so
     the memory hot-plug and resource management related code paths still
     operate under the assumption that the available address space can be
     determined with MAX_PHYSMEM_BITS.
 
     request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1
     downwards.  That means the first allocation happens past the end of the
     direct map and if unlucky this address is in the vmalloc space, which
     causes high_memory to become greater than VMALLOC_START and consequently
     causes iounmap() to fail for valid ioremap addresses.
 
     Cure this by exposing the end of the direct map via PHYSMEM_END and use
     that for the memory hot-plug and resource management related places
     instead of relying on MAX_PHYSMEM_BITS. In the KASLR case PHYSMEM_END
     maps to a variable which is initialized by the KASLR initialization and
     otherwise it is based on MAX_PHYSMEM_BITS as before.
 
   - Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of
     an initialized variabled on the stack to the VMM. The variable is only
     required as output value, so it does not have to exposed to the VMM in
     the first place.
 
   - Prevent an array overrun in the resource control code on systems with
     Sub-NUMA Clustering enabled because the code failed to adjust the index
     by the number of SNC nodes per L3 cache.

Pull x86 fixes from Thomas Gleixner:

 - x2apic_disable() clears x2apic_state and x2apic_mode unconditionally,
   even when the state is X2APIC_ON_LOCKED, which prevents the kernel to
   disable it thereby creating inconsistent state.

   Reorder the logic so it actually works correctly

 - The XSTATE logic for handling LBR is incorrect as it assumes that
   XSAVES supports LBR when the CPU supports LBR. In fact both
   conditions need to be true. Otherwise the enablement of LBR in the
   IA32_XSS MSR fails and subsequently the machine crashes on the next
   XRSTORS operation because IA32_XSS is not initialized.

   Cache the XSTATE support bit during init and make the related
   functions use this cached information and the LBR CPU feature bit to
   cure this.

 - Cure a long standing bug in KASLR

   KASLR uses the full address space between PAGE_OFFSET and vaddr_end
   to randomize the starting points of the direct map, vmalloc and
   vmemmap regions. It thereby limits the size of the direct map by
   using the installed memory size plus an extra configurable margin for
   hot-plug memory. This limitation is done to gain more randomization
   space because otherwise only the holes between the direct map,
   vmalloc, vmemmap and vaddr_end would be usable for randomizing.

   The limited direct map size is not exposed to the rest of the kernel,
   so the memory hot-plug and resource management related code paths
   still operate under the assumption that the available address space
   can be determined with MAX_PHYSMEM_BITS.

   request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1
   downwards. That means the first allocation happens past the end of
   the direct map and if unlucky this address is in the vmalloc space,
   which causes high_memory to become greater than VMALLOC_START and
   consequently causes iounmap() to fail for valid ioremap addresses.

   Cure this by exposing the end of the direct map via PHYSMEM_END and
   use that for the memory hot-plug and resource management related
   places instead of relying on MAX_PHYSMEM_BITS. In the KASLR case
   PHYSMEM_END maps to a variable which is initialized by the KASLR
   initialization and otherwise it is based on MAX_PHYSMEM_BITS as
   before.

 - Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of
   an initialized variabled on the stack to the VMM. The variable is
   only required as output value, so it does not have to exposed to the
   VMM in the first place.

 - Prevent an array overrun in the resource control code on systems with
   Sub-NUMA Clustering enabled because the code failed to adjust the
   index by the number of SNC nodes per L3 cache.

35667a2969 ARM: SoC fixes for 6.11, part 2
There is a fairly large number of bug fixes for Qualcomm platforms,
 most of them addressing issues with the devicetree files for the
 newly added Snapdragon X1 based laptops to make them more reliable.
 The Qualcomm driver changes address a few build-time issues as well
 as runtime problems in the tzmem and scm firmware, the USB Type-C
 driver, and the cmd-db and pmic_glink soc drivers.
 
 The NXP i.MX usually gets a bunch of devicetree fixes that is proportional
 to the number of supported machines. This includes both warning fixes
 and correctness for the 64-bit i.MX9, i.MX8 and layerscape platforms,
 as well as a single fix for a 32-bit i.MX6 based board.
 
 The other changes are the usual minor changes, including an update to the
 MAINTAINERS file, an omap3 dts file and a SoC driver for mpfs (risc-v).
