2022-06-27drm/i915: Prefer "XEHP_" prefix for registersMatt Roper
We've been introducing new registers with a mix of "XEHP_" (architecture) and "XEHPSDV_" (platform) prefixes. For consistency, let's settle on "XEHP_" as the preferred form. XEHPSDV_RP_STATE_CAP stays with its current name since that's truly a platform-specific register and not something that applies to the Xe_HP architecture as a whole.

XEHPSDV_FLAT_CCS_BASE_ADDR, GEN8_L3_LRA_1_GPGPU, and MMCD_MISC_CTRL were duplicated between i915_reg.h and intel_gt_regs.h. These are all GT registers, so we should drop the copy from i915_reg.h. XEHPSDV_TILE0_ADDR_RANGE was defined in i915_reg.h, but really belongs in intel_gt_regs.h. Move it.

2022-06-27eeprom: at25: Rework buggy read splittingGeert Uytterhoeven
The recent change to split reads into chunks has several problems: 1. If an SPI controller has no transfer size limit, max_chunk is SIZE_MAX, and num_msgs becomes zero, causing no data to be read into the buffer, and exposing the original contents of the buffer to userspace, 2. If the requested read size is not a multiple of the maximum transfer size, the last transfer reads too much data, overflowing the buffer, 3. The loop logic differs from the write case. Fix the above by: 1. Keeping track of the number of bytes that are still to be transferred, instead of precalculating the number of messages and keeping track of the number of bytes tranfered, 2. Calculating the transfer size of each individual message, taking into account the number of bytes left, 3. Switching from a "while"-loop to a "do-while"-loop, and renaming "msg_count" to "segment". While at it, drop the superfluous cast from "unsigned int" to "unsigned int", also from at25_ee_write(), where it was probably copied from.

2022-06-27vhost-vdpa: call vhost_vdpa_cleanup during the releaseStefano Garzarella
Before commit 3d5698793897 ("vhost-vdpa: introduce asid based IOTLB") we call vhost_vdpa_iotlb_free() during the release to clean all regions mapped in the iotlb. That commit removed vhost_vdpa_iotlb_free() and added vhost_vdpa_cleanup() to do some cleanup, including deleting all mappings, but we forgot to call it in vhost_vdpa_release(). This causes that if an application does not remove all mappings explicitly (or it crashes), the mappings remain in the iotlb and subsequent applications may fail if they map the same addresses. Calling vhost_vdpa_cleanup() also fixes a memory leak since we are not freeing `v->vdev.vqs` during the release from the same commit. Since vhost_vdpa_cleanup() calls vhost_dev_cleanup() we can remove its call from vhost_vdpa_release().

2022-06-27virtio_mmio: Restore guest page size on resumeStephan Gerhold
Virtio devices might lose their state when the VMM is restarted after a suspend to disk (hibernation) cycle. This means that the guest page size register must be restored for the virtio_mmio legacy interface, since otherwise the virtio queues are not functional. This is particularly problematic for QEMU that currently still defaults to using the legacy interface for virtio_mmio. Write the guest page size register again in virtio_mmio_restore() to make legacy virtio_mmio devices work correctly after hibernation.

2022-06-27virtio_mmio: Add missing PM calls to freeze/restoreStephan Gerhold
Most virtio drivers provide freeze/restore callbacks to finish up device usage before suspend and to reinitialize the virtio device after resume. However, these callbacks are currently only called when using virtio_pci. virtio_mmio does not have any PM ops defined. This causes problems for example after suspend to disk (hibernation), since the virtio devices might lose their state after the VMM is restarted. Calling virtio_device_freeze()/restore() ensures that the virtio devices are re-initialized correctly. Fix this by implementing the dev_pm_ops for virtio_mmio, similar to virtio_pci_common.

2022-06-27caif_virtio: fix race between virtio_device_ready() and ndo_open()Jason Wang
We currently depend on probe() calling virtio_device_ready() - which happens after netdev registration. Since ndo_open() can be called immediately after register_netdev, this means there exists a race between ndo_open() and virtio_device_ready(): the driver may start to use the device (e.g. TX) before DRIVER_OK which violates the spec. Fix this by switching to use register_netdevice() and protect the virtio_device_ready() with rtnl_lock() to make sure ndo_open() can only be called after virtio_device_ready().

2022-06-27drm/i915: tweak the ordering in cpu_write_needs_clflushMatthew Auld
For imported dma-buf objects we leave the object as cache_coherent = 0 across all platforms, which is reasonable given that have no clue what the memory underneath is, and its not like the driver can ever manually clflush the pages anyway (like with i915_gem_clflush_object) for such objects. However on discrete we choose to treat cache_dirty = true as a programmer error, leading to a warning. The simplest fix looks to be to just change the ordering in cpu_write_needs_clflush to prevent ever setting cache_dirty for dma-buf objects on discrete.

2022-06-27drm/fb-helper: Fix out-of-bounds accessThomas Zimmermann
Clip memory range to screen-buffer size to avoid out-of-bounds access in fbdev deferred I/O's damage handling. Fbdev's deferred I/O can only track pages. From the range of pages, the damage handler computes the clipping rectangle for the display update. If the fbdev screen buffer ends near the beginning of a page, that page could contain more scanlines. The damage handler would then track these non-existing scanlines as dirty and provoke an out-of-bounds access during the screen update. Hence, clip the maximum memory range to the size of the screen buffer. While at it, rename the variables min/max to min_off/max_off in drm_fb_helper_deferred_io(). This avoids confusion with the macros of the same name.

2022-06-27drm: Implement DRM aperture helpers under video/Thomas Zimmermann
Implement DRM's aperture helpers under video/ for sharing with other sub-systems. Remove DRM-isms from the interface. The helpers track the ownership of framebuffer apertures and provide hand-over from firmware, such as EFI and VESA, to native graphics drivers. Other subsystems, such as fbdev and vfio, also have to maintain ownership of framebuffer apertures. Moving DRM's aperture helpers to a more public location allows all subsystems to interact with each other and share a common implementation. The aperture helpers are selected by the various firmware drivers within DRM and fbdev, and the VGA text-console driver. The original DRM interface is kept in place for use by DRM drivers. v3: * prefix all interfaces with aperture_ (Javier) * rework and simplify documentation (Javier) * rename struct dev_aperture to struct aperture_range * rebase onto latest DRM * update MAINTAINERS entry Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Tested-by: Laszlo Ersek <lersek@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220622140134.12763-3-tzimmermann@suse.de

2022-06-24net: dp83822: disable rx error interruptEnguerrand de Ribaucourt
Some RX errors, notably when disconnecting the cable, increase the RCSR register. Once half full (0x7fff), an interrupt flood is generated. I measured ~3k/s interrupts even after the RX errors transfer was stopped. Since we don't read and clear the RCSR register, we should disable this interrupt.

2022-06-24net: dp83822: disable false carrier interruptEnguerrand de Ribaucourt
When unplugging an Ethernet cable, false carrier events were produced by the PHY at a very high rate. Once the false carrier counter full, an interrupt was triggered every few clock cycles until the cable was replugged. This resulted in approximately 10k/s interrupts. Since the false carrier counter (FCSCR) is never used, we can safely disable this interrupt. In addition to improving performance, this also solved MDIO read timeouts I was randomly encountering with an i.MX8 fec MAC because of the interrupt flood. The interrupt count and MDIO timeout fix were tested on a v5.4.110 kernel.
