From looking at the PCI IDs, every device supported by intelfb is also supported by i915. Anyone still using intelfb should please move on to i915, which does everything intelfb does but better. Removing intelfb is motivated by the driver's excessive use of the global screen_info state. The state belongs to architecture and firmware code; device drivers should not attempt to access it. But fixing intelfb would require a significant change in the driver's probing logic. As intelfb has been obsolete for nearly 2 decades, it is probably not worth the effort. Let's just remove it. Also remove the related documentation. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maik Broemme <mbroemme@libmpq.org> Signed-off-by: Helge Deller <deller@gmx.de>

Do not clear the global instance of screen_info. If necessary, clearing fields in screen_info should be done by architecture or firmware code that maintains the firmware framebuffer.

After consuming the global screen_info_state in sysfb_init(), the created platform device maintains the firmware framebuffer. Clear screen_info to avoid conflicting access.

Replace use of screen_info state with the correct interfaces from the aperture helpers. The state is only for architecture and firmware code. It is not guaranteed to contain valid data. Drivers are thus not allowed to use it. For removing conflicting firmware framebuffers, there are aperture helpers. Hence replace screen_info with the correct functions that will remove conflicting framebuffers for the hypervfb driver. For GEN1 PCI devices, the driver reads the framebuffer base and size from the PCI BAR, and uses the range for removing the firmware framebuffer. For GEN2 VMBUS devices no range can be detected, so the driver clears all firmware framebuffers.

When built-in, the sis driver tries to detect the current display mode from the global screen_info state. That state is only for architecture and firmware code. Drivers should not use it directly as it's not guaranteed to contain valid information. Remove the mode-detection code from sis. Drivers that want to detect a pre-set mode on probe should read the hardware registers directly. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Helge Deller <deller@gmx.de>

Allocate stifb's instance of fb_info with framebuffer_alloc(). This is the preferred way of creating fb_info with associated driver data stored in struct fb_info.par. Requires several, but minor, changes through out the driver's code. The intended side effect of this patch is that the new instance of struct fb_info now has its device field correctly set to the parent device of the STI ROM. A later patch can detect if the device is the firmware's primary output. It is also now correctly located within the Linux device hierarchy.

Thomas Zimmermann authored
Store the ROM's parent device in each STI struct, so we can associate the STI framebuffer with a device. The new field will eventually replace the fbdev subsystem's info field, which the function fb_is_primary_device() currently requires to detect the firmware's output. By using the device instead of the framebuffer info, a later patch can generalize the helper for use in non-fbdev code.

When framebuffer gets closed, the queued deferred IO gets cancelled. This can cause some last display data to vanish. This is problematic for users who send a still image to the framebuffer, then close the file: the image may never appear. To ensure none of display data get lost, flush the queued deferred IO first before closing. Another possible solution is to delete the cancel_delayed_work_sync() instead. The difference is that the display may appear some time after closing. However, the clearing of page mapping after this needs to be removed too, because the page mapping is used by the deferred work. It is not completely obvious whether it is okay to not clear the page mapping. For a patch intended for stable trees, go with the simple and obvious solution.

Nam Cao authored
The driver's fsync() is supposed to flush any pending operation to hardware. It is implemented in this driver by cancelling the queued deferred IO first, then schedule it for "immediate execution" by calling schedule_delayed_work() again with delay=0. However, setting delay=0 only means the work is scheduled immediately, it does not mean the work is executed immediately. There is no guarantee that the work is finished after schedule_delayed_work() returns. After this driver's fsync() returns, there can still be pending work. Furthermore, if close() is called by users immediately after fsync(), the pending work gets cancelled and fsync() may do nothing. To ensure that the deferred IO completes, use flush_delayed_work() instead. Write operations to this driver either write to the device directly, or invoke schedule_delayed_work(); so by flushing the workqueue, it can be guaranteed that all previous writes make it to the device.

We have managed to ascertain that all users of the old FBDEV code that are out of tree are now gone. The new DRM driver can be found in drivers/gpu/drm/pl111/. The remaining out of tree user was the ARM FVP emulation platform, running Android. Thanks to changes in Android versions 13 and 14, Android can now use the DRM driver when being emulated under FVP. Some final patches are being put in place to make it fully featured.

The previous setting did not take into account the CSTN mode. For the H_WAIT_2 bitfield (bits 0-7) of the LCDC Horizontal Configuration Register (LCDCR), the IMX25RM manual states that: In TFT mode, it specifies the number of SCLK periods between the end of HSYNC and the beginning of OE signal, and the total delay time equals (H_WAIT_2 + 3) of SCLK periods. In CSTN mode, it specifies the number of SCLK periods between the end of HSYNC and the first display data in each line, and the total delay time equals (H_WAIT_2 + 2) of SCLK periods.

As result, all the ugly bit checks are replaced by simple evaluations of the required bit fields. - Improve handling of some weird scenarios between service element (SE) host and SE guest with adjunct-processor (AP) pass-through support. - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the previous value of the to be changed control register. This is useful if a bit is only changed temporarily and the previous content needs to be restored. - The kernel starts with machine checks disabled and is expected to enable it once trap_init() is called. However the implementation allows machine checks early. Consistently enable it in trap_init() only. - local_mcck_disable() and local_mcck_enable() assume that machine checks are always enabled. Instead implement and use local_mcck_save() and local_mcck_restore() to disable machine checks and restore the previous state. - Modification of floating point control (FPC) register of a traced process using ptrace interface may lead to corruption of the FPC register of the tracing process. Fix this. - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point control (FPC) register in vCPU, but may lead to corruption of the FPC register of the host process. Fix this. - Use READ_ONCE() to read a vCPU floating point register value from the memory mapped area. This avoids that, depending on code generation, a different value is tested for validity than the one that is used. - Get rid of test_fp_ctl(), since it is quite subtle to use it correctly. Instead copy a new floating point control register value into its save area and test the validity of the new value when loading it. - Remove superfluous save_fpu_regs() call. - Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines provide the vector facility since many years and the need to make the task structure size dependent on the vector facility does not exist. - Remove the "novx" kernel command line option, as the vector code runs without any problems since many years. - Add the vector facility to the z13 architecture level set (ALS). All hypervisors support the vector facility since many years. This allows compile time optimizations of the kernel. - Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As result, the compiled code will have less runtime checks and less code. - Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C. - Convert the struct subchannel spinlock from pointer to member. * tag 's390-6.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (24 commits) Revert "s390: update defconfigs" s390/cio: make sch->lock spinlock pointer a member s390: update defconfigs s390/mm: convert pgste locking functions to C s390/fpu: get rid of MACHINE_HAS_VX s390/als: add vector facility to z13 architecture level set s390/fpu: remove "novx" option s390/fpu: remove ARCH_WANTS_DYNAMIC_TASK_STRUCT support KVM: s390: remove superfluous save_fpu_regs() call s390/fpu: get rid of test_fp_ctl() KVM: s390: use READ_ONCE() to read fpc register value KVM: s390: fix setting of fpc register s390/ptrace: handle setting of fpc register correctly s390/nmi: implement and use local_mcck_save() / local_mcck_restore() s390/nmi: consistently enable machine checks in trap_init() s390/ctlreg: return old register contents when changing bits s390/ap: handle outband SE bind state change s390/ap: store TAPQ hwinfo in struct ap_card s390/vfio-ap: fix sysfs status attribute for AP queue devices s390/vfio-ap: improve reaction to response code 07 from PQAP(AQIC) command ...

Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. In the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7 we had all arch/ and drivers/ modified to remove the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only. The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches are still being reviewed. After that we then can expect also the removal of the no longer needed check for procname == NULL. Let us recap the purpose of this work: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further work by Thomas Weißschuh with the constificatin of the struct ctl_table. Due to Joel Granados's work, and to help bring in new blood, I have suggested for him to become a maintainer and he's accepted.

Pull bcachefs updates from Kent Overstreet: - btree write buffer rewrite: instead of adding keys to the btree write buffer at transaction commit time, we now journal them with a different journal entry type and copy them from the journal to the write buffer just prior to journal write. This reduces the number of atomic operations on shared cachelines in the transaction commit path and is a signicant performance improvement on some workloads: multithreaded 4k random writes went from ~650k iops to ~850k iops. - Bring back optimistic spinning for six locks: the new implementation doesn't use osq locks; instead we add to the lock waitlist as normal, and then spin on the lock_acquired bit in the waitlist entry, _not_ the lock itself. - New ioctls: - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck but without mounting: useful for transparently using the kernel version of fsck from 'bcachefs fsck' when the kernel version is a better match for the on disk filesystem. - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet, but the passes that are supported are fully featured - errors may be corrected as normal. The new ioctls use the new 'thread_with_file' abstraction for kicking off a kthread that's tied to a file descriptor returned to userspace via the ioctl. - btree_paths within a btree_trans are now dynamically growable, instead of being limited to 64.

Fix the size check added to dns_resolver_preparse() for the V1 server-list header so that it doesn't give EINVAL if the size supplied is the same as the size of the header struct (which should be valid). This can be tested with: echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p which will give "add_key: Invalid argument" without this fix. Fixes: 1997b3cb ("keys, dns: Fix missing size check of V1 server-list header") Reported-by: Pengfei Xu <pengfei.xu@intel.com> Link: https://lore.kernel.org/r/ZZ4fyY4r3rqgZL+4@xpf.sh.intel.com/Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
