[PATCH v3] iommu/virtio: Fix interaction with VFIO

by Jean-Philippe Brucker

Commit e8ae0e140c05 ("vfio: Require that devices support DMA cache coherence") requires IOMMU drivers to advertise IOMMU_CAP_CACHE_COHERENCY, in order to be used by VFIO. Since VFIO does not provide to userspace the ability to maintain coherency through cache invalidations, it requires hardware coherency. Advertise the capability in order to restore VFIO support. The meaning of IOMMU_CAP_CACHE_COHERENCY also changed from "IOMMU can enforce cache coherent DMA transactions" to "IOMMU_CACHE is supported". While virtio-iommu cannot enforce coherency (of PCIe no-snoop transactions), it does support IOMMU_CACHE. We can distinguish different cases of non-coherent DMA: (1) When accesses from a hardware endpoint are not coherent. The host would describe such a device using firmware methods ('dma-coherent' in device-tree, '_CCA' in ACPI), since they are also needed without a vIOMMU. In this case mappings are created without IOMMU_CACHE. virtio-iommu doesn't need any additional support. It sends the same requests as for coherent devices. (2) When the physical IOMMU supports non-cacheable mappings. Supporting those would require a new feature in virtio-iommu, new PROBE request property and MAP flags. Device drivers would use a new API to discover this since it depends on the architecture and the physical IOMMU. (3) When the hardware supports PCIe no-snoop. It is possible for assigned PCIe devices to issue no-snoop transactions, and the virtio-iommu specification is lacking any mention of this. Arm platforms don't necessarily support no-snoop, and those that do cannot enforce coherency of no-snoop transactions. Device drivers must be careful about assuming that no-snoop transactions won't end up cached; see commit e02f5c1bb228 ("drm: disable uncached DMA optimization for ARM and arm64"). On x86 platforms, the host may or may not enforce coherency of no-snoop transactions with the physical IOMMU. But according to the above commit, on x86 a driver which assumes that no-snoop DMA is compatible with uncached CPU mappings will also work if the host enforces coherency. Although these issues are not specific to virtio-iommu, it could be used to facilitate discovery and configuration of no-snoop. This would require a new feature bit, PROBE property and ATTACH/MAP flags.

[PATCH v2 1/2] drm/amdgpu: Move HDP remapping earlier during init

by Lijo Lazar

HDP flush is used early in the init sequence as part of memory controller block initialization. Hence remapping of HDP registers needed for flush needs to happen earlier. This also fixes the Unsupported Request error reported through AER during driver load. The error happens as a write happens to the remap offset before real remapping is done. Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373 The error was unnoticed before and got visible because of the commit referenced below. This doesn't fix anything in the commit below, rather fixes the issue in amdgpu exposed by the commit. The reference is only to associate this commit with below one so that both go together.

[PATCH v3 1/3] btrfs: enhance unsupported compat RO flags handling

by Qu Wenruo

Currently there are two corner cases not handling compat RO flags correctly: - Remount We can still mount the fs RO with compat RO flags, then remount it RW. We should not allow any write into a fs with unsupported RO flags. - Still try to search block group items In fact, behavior/on-disk format change to extent tree should not need a full incompat flag. And since we can ensure fs with unsupported RO flags never got any writes (with above case fixed), then we can even skip block group items search at mount time. This patch will enhance the unsupported RO compat flags by: - Reject RW remount if there is unsupported RO compat flags - Go dummy block group items directly for unsupported RO compat flags In fact, only changes to chunk/subvolume/root/csum trees should go incompat flags. The latter part should allow future change to extent tree to be compat RO flags. Thus this patch also needs to be backported to all stable trees.

[PATCH -next] sched/cputime: Fix the bug of reading time backward from /proc/stat

by Li Hua

The problem that the statistical time goes backward, the value read first is 319, and the value read again is 318. As follows： first： cat /proc/stat | grep cpu1 cpu1 319 0 496 41665 0 0 0 0 0 0 then： cat /proc/stat | grep cpu1 cpu1 318 0 497 41674 0 0 0 0 0 0 Time goes back, which is counterintuitive.

[PATCH v2 1/3] xen-blkback: Advertise feature-persistent as user requested

by SeongJae Park

The advertisement of the persistent grants feature (writing 'feature-persistent' to xenbus) should mean not the decision for using the feature but only the availability of the feature. However, commit aac8a70db24b ("xen-blkback: add a parameter for disabling of persistent grants") made a field of blkback, which was a place for saving only the negotiation result, to be used for yet another purpose: caching of the 'feature_persistent' parameter value. As a result, the advertisement, which should follow only the parameter value, becomes inconsistent. This commit fixes the misuse of the semantic by making blkback saves the parameter value in a separate place and advertises the support based on only the saved value.

[PATCH 01/11] drm/edid: Handle EDID 1.4 range descriptor h/vfreq offsets

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> EDID 1.4 introduced some extra flags in the range descriptor to support min/max h/vfreq >= 255. Consult them to correctly parse the vfreq limits. Note that some combinations of the flags are documented as "reserved" (as are some other values in the descriptor) but explicitly checking for those doesn't seem particularly worthwile since we end up with bogus results whether we decode them or not. v2: Increase the storage to u16 to make it work (Jani) Note the "reserved" values situation (Jani) v3: Document the EDID version number in the defines Drop some bogus (u8) casts Cc: stable(a)vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/6519 Reviewed-by: Jani Nikula <jani.nikula(a)intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala(a)linux.intel.com> --- drivers/gpu/drm/drm_debugfs.c | 4 ++-- drivers/gpu/drm/drm_edid.c | 24 ++++++++++++++++++------ include/drm/drm_connector.h | 4 ++-- include/drm/drm_edid.h | 5 +++++ 4 files changed, 27 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/drm_debugfs.c b/drivers/gpu/drm/drm_debugfs.c index 493922069c90..01ee3febb813 100644 --- a/drivers/gpu/drm/drm_debugfs.c +++ b/drivers/gpu/drm/drm_debugfs.c @@ -377,8 +377,8 @@ static int vrr_range_show(struct seq_file *m, void *data) if (connector->status != connector_status_connected) return -ENODEV; - seq_printf(m, "Min: %u\n", (u8)connector->display_info.monitor_range.min_vfreq); - seq_printf(m, "Max: %u\n", (u8)connector->display_info.monitor_range.max_vfreq); + seq_printf(m, "Min: %u\n", connector->display_info.monitor_range.min_vfreq); + seq_printf(m, "Max: %u\n", connector->display_info.monitor_range.max_vfreq); return 0; } diff --git a/drivers/gpu/drm/drm_edid.c b/drivers/gpu/drm/drm_edid.c index 90a5e26eafa8..4005dab6147d 100644 --- a/drivers/gpu/drm/drm_edid.c +++ b/drivers/gpu/drm/drm_edid.c @@ -6020,12 +6020,14 @@ static void drm_parse_cea_ext(struct drm_connector *connector, } static -void get_monitor_range(const struct detailed_timing *timing, - void *info_monitor_range) +void get_monitor_range(const struct detailed_timing *timing, void *c) { - struct drm_monitor_range_info *monitor_range = info_monitor_range; + struct detailed_mode_closure *closure = c; + struct drm_display_info *info = &closure->connector->display_info; + struct drm_monitor_range_info *monitor_range = &info->monitor_range; const struct detailed_non_pixel *data = &timing->data.other_data; const struct detailed_data_monitor_range *range = &data->data.range; + const struct edid *edid = closure->drm_edid->edid; if (!is_display_descriptor(timing, EDID_DETAIL_MONITOR_RANGE)) return; @@ -6041,18 +6043,28 @@ void get_monitor_range(const struct detailed_timing *timing, monitor_range->min_vfreq = range->min_vfreq; monitor_range->max_vfreq = range->max_vfreq; + + if (edid->revision >= 4) { + if (data->pad2 & DRM_EDID_RANGE_OFFSET_MIN_VFREQ) + monitor_range->min_vfreq += 255; + if (data->pad2 & DRM_EDID_RANGE_OFFSET_MAX_VFREQ) + monitor_range->max_vfreq += 255; + } } static void drm_get_monitor_range(struct drm_connector *connector, const struct drm_edid *drm_edid) { - struct drm_display_info *info = &connector->display_info; + const struct drm_display_info *info = &connector->display_info; + struct detailed_mode_closure closure = { + .connector = connector, + .drm_edid = drm_edid, + }; if (!version_greater(drm_edid, 1, 1)) return; - drm_for_each_detailed_block(drm_edid, get_monitor_range, - &info->monitor_range); + drm_for_each_detailed_block(drm_edid, get_monitor_range, &closure); DRM_DEBUG_KMS("Supported Monitor Refresh rate range is %d Hz - %d Hz\n", info->monitor_range.min_vfreq, diff --git a/include/drm/drm_connector.h b/include/drm/drm_connector.h index 248206bbd975..56aee949c6fa 100644 --- a/include/drm/drm_connector.h +++ b/include/drm/drm_connector.h @@ -319,8 +319,8 @@ enum drm_panel_orientation { * EDID's detailed monitor range */ struct drm_monitor_range_info { - u8 min_vfreq; - u8 max_vfreq; + u16 min_vfreq; + u16 max_vfreq; }; /** diff --git a/include/drm/drm_edid.h b/include/drm/drm_edid.h index 2181977ae683..1ed61e2b30a4 100644 --- a/include/drm/drm_edid.h +++ b/include/drm/drm_edid.h @@ -92,6 +92,11 @@ struct detailed_data_string { u8 str[13]; } __attribute__((packed)); +#define DRM_EDID_RANGE_OFFSET_MIN_VFREQ (1 << 0) /* 1.4 */ +#define DRM_EDID_RANGE_OFFSET_MAX_VFREQ (1 << 1) /* 1.4 */ +#define DRM_EDID_RANGE_OFFSET_MIN_HFREQ (1 << 2) /* 1.4 */ +#define DRM_EDID_RANGE_OFFSET_MAX_HFREQ (1 << 3) /* 1.4 */ + #define DRM_EDID_DEFAULT_GTF_SUPPORT_FLAG 0x00 #define DRM_EDID_RANGE_LIMITS_ONLY_FLAG 0x01 #define DRM_EDID_SECONDARY_GTF_SUPPORT_FLAG 0x02 -- 2.35.1
