Geert Uytterhoeven <geert+renesas@glider.be> says:
This patch series adds CAN-FD Transceiver Delay Compensation support to
the R-Car CAN-FD driver, after the customary cleanups and refactorings.
Changes compared to v1 [1]:
- Dropped patch "can: rcar_canfd: Use ndev parameter in
rcar_canfd_set_bittiming()",
- New patch "[PATCH v2 02/10] can: rcar_canfd: Remove bittiming debug
prints",
- New patch "[PATCH v2 07/10] can: rcar_canfd: Rename
rcar_canfd_setrnc() to rcar_canfd_set_rnc()",
- Add Reviewed-by,
- Replace function-like RCANFD_F_*() macros by rcar_canfd_f_*()
inline functions,
- Replace function-like macro RCANFD_FDSTS_TDCR() by bitmask
RCANFD_FDSTS_TDCR and helper function rcar_canfd_get_tdcr(),
- Replace function-like macro RCANFD_FDSTS_TDCVF() by two bit
definitions,
- Drop debug print of tdc mode and tdco value.
This has been tested on R-Car V4H (White Hawk), V4M (Gray Hawk Single),
and E3 (Ebisu-4D[2]), using various data bit rates. Without proper TDC
configuration, transmitting at 8 Mbps makes the CAN-FD controller enter
BUS-OFF state. The TDCV value as measured by the CAN-FD controller is 4
on all boards tested (base clock 40 MHz, i.e. 25 ns period), and ca. 90
ns as measured by a logic analyzer on Gray Hawk Single.
Note that the BSP (predating upstream TDC support), uses a much simpler
method: for transfer rates >= 5 Mbps on R-Car Gen4, it enables TDC with
a hardcoded (hardware) TDCO value of 2 (i.e. actual 3), which matches
the behavior of this series at 8 Mbps.
[1] "[PATCH 0/9] can: rcar_canfd: Add support for Transceiver Delay Compensation"
https://lore.kernel.org/cover.1748863848.git.geert+renesas@glider.be
[2] r8a77990.dtsi configures the CANFD core clock to 40 MHz, limiting
transfer rates to 4 Mbps. Enable support for 8 Mbps by adding to
ebisu.dtsi:
&canfd {
assigned-clock-rates = <80000000>;
}
I plan to send patches to update this on all R-Car Gen3 and RZ/G2
SoCs once this series has reached upstream.

The Renesas CAN-FD hardware block supports configuring Transceiver Delay
Compensation, and reading back the Transceiver Delay Compensation
Result, which is needed to support high transfer rates like 8 Mbps.
The Secondary Sample Point is either the measured delay plus the
configured offset, or just the configured offset.
Fix the existing RCANFD_FDCFG_TDCO() macro for the intended use case
(writing instead of reading the field). Add register definition bits
for the Channel n CAN-FD Status Register.

Xe can free some of the data pointed to by the dma-fences it exports. Most
notably the timeline name can get freed if userspace closes the associated
submit queue. At the same time the fence could have been exported to a
third party (for example a sync_fence fd) which will then cause an use-
after-free on subsequent access.
To make this safe we need to make the driver compliant with the newly
documented dma-fence rules. Driver has to ensure a RCU grace period
between signalling a fence and freeing any data pointed to by said fence.
For the timeline name we simply make the queue be freed via kfree_rcu and
for the shared lock associated with multiple queues we add a RCU grace
period before freeing the per GT structure holding the lock.

Dma-fence objects currently suffer from a potential use after free problem
where fences exported to userspace and other drivers can outlive the
exporting driver, or the associated data structures.
The discussion on how to address this concluded that adding reference
counting to all the involved objects is not desirable, since it would need
to be very wide reaching and could cause unloadable drivers if another
entity would be holding onto a signaled fence reference potentially
indefinitely.
This patch enables the safe access by introducing and documenting a
contract between fence exporters and users. It documents a set of
contraints and adds helpers which a) drivers with potential to suffer from
the use after free must use and b) users of the dma-fence API must use as
well.
Premise of the design has multiple sides:
1. Drivers (fence exporters) MUST ensure a RCU grace period between
signalling a fence and freeing the driver private data associated with it.
The grace period does not have to follow the signalling immediately but
HAS to happen before data is freed.
2. Users of the dma-fence API marked with such requirement MUST contain
the complete access to the data within a single code block guarded by
rcu_read_lock() and rcu_read_unlock().
The combination of the two ensures that whoever sees the
DMA_FENCE_FLAG_SIGNALED_BIT not set is guaranteed to have access to a
valid fence->lock and valid data potentially accessed by the fence->ops
virtual functions, until the call to rcu_read_unlock().
3. Module unload (fence->ops) disappearing is for now explicitly not
handled. That would required a more complex protection, possibly needing
SRCU instead of RCU to handle callers such as dma_fence_release() and
dma_fence_wait_timeout(), where race between
dma_fence_enable_sw_signaling, signalling, and dereference of
fence->ops->wait() would need a sleeping SRCU context.

Protect the access to driver and timeline name which otherwise could be

This prepares the code for incoming dma-fence API changes which will start
asserting these accesses are done from a RCU locked section.
Now that the safe access is handled in the dma-fence API, the external
callers such as sync_file, and our internal code paths, we can drop the
similar protection from i915_fence_get_timeline_name().

VFIO EEH recovery for PCI passthrough devices fails on PowerNV and pseries
platforms due to missing host-side PE bridge reconfiguration. In the
current implementation, eeh_pe_configure() only performs RTAS or OPAL-based
bridge reconfiguration for native host devices, but skips it entirely for
PEs managed through VFIO in guest passthrough scenarios.
This leads to incomplete EEH recovery when a PCI error affects a
passthrough device assigned to a QEMU/KVM guest. Although VFIO triggers the
EEH recovery flow through VFIO_EEH_PE_ENABLE ioctl, the platform-specific
bridge reconfiguration step is silently bypassed. As a result, the PE's
config space is not fully restored, causing subsequent config space access
failures or EEH freeze-on-access errors inside the guest.
This patch fixes the issue by ensuring that eeh_pe_configure() always
invokes the platform's configure_bridge() callback (e.g.,
pseries_eeh_phb_configure_bridge) even for VFIO-managed PEs. This ensures
that RTAS or OPAL calls to reconfigure the PE bridge are correctly issued
on the host side, restoring the PE's configuration space after an EEH
event.
This fix is essential for reliable EEH recovery in QEMU/KVM guests using
VFIO PCI passthrough on PowerNV and pseries systems.
Tested with:
- QEMU/KVM guest using VFIO passthrough (IBM Power9,(lpar)Power11 host)
- Injected EEH errors with pseries EEH errinjct tool on host, recovery
verified on qemu guest.
- Verified successful config space access and CAP_EXP DevCtl restoration
after recovery
