2020-10-21xen-blkback: add a parameter for disabling of persistent grantsSeongJae Park
Persistent grants feature provides high scalability. On some small systems, however, it could incur data copy overheads[1] and thus it is required to be disabled. But, there is no option to disable it. For the reason, this commit adds a module parameter for disabling of the feature.

2020-10-21drm/i915/display: Add Nearest-neighbor based integer scaling supportPankaj Bharadiya
Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier.Nearest-neighbor (NN) interpolation works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. Both IS and NN preserve the clarity of the original image. Integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look. Introduce functions to configure the scaler filter coefficients to enable nearest-neighbor filtering.

2020-10-21drm: Introduce plane and CRTC scaling filter propertiesPankaj Bharadiya
Introduce per-plane and per-CRTC scaling filter properties to allow userspace to select the driver's default scaling filter or Nearest-neighbor(NN) filter for upscaling operations on CRTC and plane. Drivers can set up this property for a plane by calling drm_plane_create_scaling_filter() and for a CRTC by calling drm_crtc_create_scaling_filter(). NN filter works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. NN filter for integer multiple scaling can be particularly useful for for pixel art games that rely on sharp, blocky images to deliver their distinctive look. changes since: v6: * Move property doc to existing "Standard CRTC Properties" and "Plane Composition Properties" doc comments (Simon) changes since v3: * Refactor code, add new function for common code (Ville) changes since v2: * Create per-plane and per-CRTC scaling filter property (Ville) changes since v1: * None changes since RFC: * Add separate properties for plane and CRTC (Ville) Link: https://github.com/xbmc/xbmc/pull/18194 Link: https://github.com/xbmc/xbmc/pull/18567 Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Uma Shankar <uma.shankar@intel.com> Acked-by: Simon Ser <contact@emersion.fr> Acked-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201020161427.6941-2-pankaj.laxminarayan.bharadiya@intel.com

2020-10-20netsec: ignore 'phy-mode' device property on ACPI systemsArd Biesheuvel
Since commit bbc4d71d63549bc ("net: phy: realtek: fix rtl8211e rx/tx delay config"), the Realtek PHY driver will override any TX/RX delay set by hardware straps if the phy-mode device property does not match. This is causing problems on SynQuacer based platforms (the only SoC that incorporates the netsec hardware), since many were built with this Realtek PHY, and shipped with firmware that defines the phy-mode as 'rgmii', even though the PHY is configured for TX and RX delay using pull-ups. From the driver's perspective, we should not make any assumptions in the general case that the PHY hardware does not require any initial configuration. However, the situation is slightly different for ACPI boot, since it implies rich firmware with AML abstractions to handle hardware details that are not exposed to the OS. So in the ACPI case, it is reasonable to assume that the PHY comes up in the right mode, regardless of whether the mode is set by straps, by boot time firmware or by AML executed by the ACPI interpreter. So let's ignore the 'phy-mode' device property when probing the netsec driver in ACPI mode, and hardcode the mode to PHY_INTERFACE_MODE_NA, which should work with any PHY provided that it is configured by the time the driver attaches to it. While at it, document that omitting the mode is permitted for DT probing as well, by setting the phy-mode DT property to the empty string.

2020-10-20gfs2: Eliminate gl_vmBob Peterson
The gfs2_glock structure has a gl_vm member, introduced in commit 7005c3e4ae428 ("GFS2: Use range based functions for rgrp sync/invalidation"), which stores the location of resource groups within their address space. This structure is in a union with iopen glock specific fields. It was introduced because at unmount time, the resource group objects were destroyed before flushing out any pending resource group glock work, and flushing out such work could require flushing / truncating the address space. Since commit b3422cacdd7e6 ("gfs2: Rework how rgrp buffer_heads are managed"), any pending resource group glock work is flushed out before destroying the resource group objects. So the resource group objects will now always exist in rgrp_go_sync and rgrp_go_inval, and we now simply compute the gl_vm values where needed instead of caching them. This also eliminates the union.

2020-10-20gfs2: Only access gl_delete for iopen glocksBob Peterson

Without this fix, we'll end up clobbering gl_vm, which results in general memory corruption.
