2021-10-07drm/i915: remove IS_ACTIVELucas De Marchi11-31/+18
When trying to bring IS_ACTIVE to linux/kconfig.h I thought it wouldn't provide much value just encapsulating it in a boolean context. So I also added the support for handling undefined macros as the IS_ENABLED() counterpart. However the feedback received from Masahiro Yamada was that it is too ugly, not providing much value. And just wrapping in a boolean context is too dumb - we could simply open code it. As detailed in commit babaab2f4738 ("drm/i915: Encapsulate kconfig constant values inside boolean predicates"), the IS_ACTIVE macro was added to workaround a compilation warning. However after checking again our current uses of IS_ACTIVE it turned out there is only 1 case in which it triggers a warning in clang (due -Wconstant-logical-operand) and 2 in smatch. All the others can simply use the shorter version, without wrapping it in any macro. So here I'm dialing all the way back to simply removing the macro. That single case hit by clang can be changed to make the constant come first, so it doesn't think it's mask: - if (context && CONFIG_DRM_I915_FENCE_TIMEOUT) + if (CONFIG_DRM_I915_FENCE_TIMEOUT && context) As talked with Dan Carpenter, that logic will be added in smatch as well, so it will also stop warning about it.

Slow path means allowing packet to go from uplink to representor and from representor to correct VF on Rx site and from VF to representor and to uplink on Tx site. To accomplish this driver, has to set correct Tx descriptor. When packet is sent from representor to VF, destination should be set to VF VSI. When packet is sent from uplink port destination should be uplink to bypass switch infrastructure and send packet outside. On Rx site driver should check source VSI field from Rx descriptor and based on that forward packed to correct netdev. To allow this there is a target netdevs table in control plane VSI struct.

2021-10-07ice: rebuild switchdev when resetting all VFsGrzegorz Nitka6-1/+130
As resetting all VFs behaves mostly like creating new VFs also eswitch infrastructure has to be recreated. The easiest way to do that is to rebuild eswitch after resetting VFs. Implement helper functions to start and stop all representors queues. This is used to disable traffic on port representors. In rebuild path: - NAPI has to be disabled - eswitch environment has to be set up - new port representors have to be created, because the old one had pointer to not existing VFs - new control plane VSI ring should be remapped - NAPI hast to be enabled - rxdid has to be set to FLEX_NIC_2, because this descriptor id support source_vsi, which is needed on control plane VSI queues - port representors queues have to be started Signed-off-by: Grzegorz Nitka <grzegorz.nitka@intel.com> Tested-by: Sandeep Penigalapati <sandeep.penigalapati@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

Disable switchdev when user change number of VFs to 0. Changing eswitch mode back to legacy when VFs are created in switchdev mode isn't allowed. As switchdev takes care of managing filter rules, adding new rules on VF is blocked.

New type of VSI has to be defined for switchdev control plane VSI. Number of allocated Tx and Rx queue has to be equal to amount of VFs, because each port representor should have one Tx and Rx queue. Also to not increase number of used irqs too much, control plane VSI uses only one q_vector and handle all queues in one irq. To allow handling all queues in one irq , new function to clean msix for eswitch was introduced. This function will schedule napi for each representor instead of scheduling it only for one like in normal clean irq function. Only one additional msix has to be requested. Always try to request it in ice_ena_msix_range function.

2021-10-07ice: set and release switchdev environmentGrzegorz Nitka6-13/+453
Switchdev environment has to be set up when user create VFs and eswitch mode is switchdev. Release is done when user delete all VFs. Data path in this implementation is based on control plane VSI. This VSI is used to pass traffic from port representors to corresponding VFs and vice versa. Default TX rule has to be added to forward packet to control plane VSI. This will redirect packets from VFs which don't match other rules to control plane VSI. On RX side default rule is added on uplink VSI to receive all traffic that doesn't match other rules. When setting switchdev environment all other rules from VFs should be removed. Packet to VFs will be forwarded by control plane VSI. As VF without any mac rules can't send any packet because of antispoof mechanism, VSI antispoof should be turned off on each VFs. To send packet from representor to correct VSI, destination VSI field in TX descriptor will have to be filled. Allow that by setting destination override bit in control plane VSI security config. Packet from VFs will be received on control plane VSI. Driver should decide to which netdev forward the packet. Decision is made based on src_vsi field from descriptor. There is a target netdev list in control plane VSI struct which choose netdev based on src_vsi number.

2021-10-07ice: introduce VF port representorMichal Swiatkowski6-2/+286
Port representor is used to manage VF from host side. To allow it each created representor registers netdevice with random hw address. Also devlink port is created for all representors. Port representor name is created based on switch id or managed by devlink core if devlink port was registered with success. Open and stop ndo ops are implemented to allow managing the VF link state. Link state is tracked in VF struct. Struct ice_netdev_priv is extended by pointer to representor field. This is needed to get correct representor from netdev struct mostly used in ndo calls. Implement helper functions to check if given netdev is netdev of port representor (ice_is_port_repr_netdev) and to get representor from netdev (ice_netdev_to_repr). As driver mostly will create or destroy port representors on all VFs instead of on single one, write functions to add and remove representor for each VF. Representor struct contains pointer to source VSI, which is VSI configured on VF, backpointer to VF, backpointer to netdev, q_vector pointer and metadata_dst which will be used in data path.

2021-10-07ice: Move devlink port to PF/VF structWojciech Drewek7-37/+103
Keeping devlink port inside VSI data structure causes some issues. Since VF VSI is released during reset that means that we have to unregister devlink port and register it again every time reset is triggered. With the new changes in devlink API it might cause deadlock issues. After calling devlink_port_register/devlink_port_unregister devlink API is going to lock rtnl_mutex. It's an issue when VF reset is triggered in netlink operation context (like setting VF MAC address or VLAN), because rtnl_lock is already taken by netlink. Another call of rtnl_lock from devlink API results in dead-lock. By moving devlink port to PF/VF we avoid creating/destroying it during reset. Since this patch, devlink ports are created during ice_probe, destroyed during ice_remove for PF and created during ice_repr_add, destroyed during ice_repr_rem for VF.

2021-10-07PCI: ACPI: Check parent pointer in acpi_pci_find_companion()Rafael J. Wysocki1-0/+3
If acpi_pci_find_companion() is called for a device whose parent pointer is NULL, it will crash when attempting to get the ACPI companion of the parent due to a NULL pointer dereference in the ACPI_COMPANION() macro. This was not a problem before commit 375553a93201 ("PCI: Setup ACPI fwnode early and at the same time with OF") that made pci_setup_device() call pci_set_acpi_fwnode() and so it allowed devices with NULL parent pointers to be passed to acpi_pci_find_companion() which is the case in pci_iov_add_virtfn(), for instance. Fix this issue by making acpi_pci_find_companion() check the device's parent pointer upfront and bail out if it is NULL. While pci_iov_add_virtfn() can be changed to set the device's parent pointer before calling pci_setup_device() for it, checking pointers against NULL before dereferencing them is prudent anyway and looking for ACPI companions of virtual functions isn't really useful.

There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure.

2021-10-07qcom_scm: hide Kconfig symbolArnd Bergmann10-14/+14
Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.

2021-10-07firmware: include drivers/firmware/Kconfig unconditionallyArnd Bergmann1-0/+2
Compile-testing drivers that require access to a firmware layer fails when that firmware symbol is unavailable. This happened twice this week: - My proposed to change to rework the QCOM_SCM firmware symbol broke on ppc64 and others. - The cs_dsp firmware patch added device specific firmware loader into drivers/firmware, which broke on the same set of architectures. We should probably do the same thing for other subsystems as well, but fix this one first as this is a dependency for other patches getting merged.
