2024-04-16drm/xe/pf: Add support to configure SR-IOV VFsMichal Wajdeczko
To run correctly, each Virtual Function must be provisioned with some chunk of shared hardware or firmware resources (like GGTT, device memory, GuC doorbell IDs, GuC context IDs) and scheduling parameters (execution quantum or preemption timeout). All resources assigned to VFs must be excluded from the PF driver use and may require some additional preparation steps (like setup of the LMTT or update of the GGTT PTE). Those provisioning details must be then sent to the GuC firmware as most of those details will be shared later with the VF drivers during their boot. Add basic functions to provision VFs with all hardware resources or scheduling parameters. We will use them shortly in upcoming patches either in manual provisioning over debugfs, exposed to the advanced users, or automatic provisioning done by PF driver during VFs enabling.

2024-04-16drm/xe/pf: Add SR-IOV PF specific early GT initializationMichal Wajdeczko
The PF driver must maintain additional GT level data per each VF. This additional per-VF data will be added in upcoming patches and will include: provisioning configuration (like GGTT space or LMEM allocation sizes or scheduling parameters), monitoring thresholds and counters, and more. As number of supported VFs varies across platforms use flexible array where first entry will contain metadata for the PF itself (if such configuration parameter is applicable for the PF) and all remaining entries will contain data for potential VFs.

In upcoming patches the PF driver will add support to change VFs configuration and will need to use PF2GUC_UPDATE_VF_CFG messages. Add necessary definitions to our GuC firmware ABI header.

2024-04-16drm/xe: Add xe_ttm_vram_get_availMichal Wajdeczko
The PF driver will need to know size of the remaining available VRAM to estimate fair VRAM allocations that could be used across all VFs in automatic VFs provisioning mode. Add helper function for that. We will use it in upcoming patch.

2024-04-16drm/xe: Allow to assign GGTT region to the VFMichal Wajdeczko
VF's drivers can't modify GGTT PTEs except the range explicitly assigned by the PF driver. To allow hardware enforcement of this requirement, each GGTT PTE has a field with the VF number that identifies which VF can modify that particular GGTT PTE entry. Only PF driver can modify this field and PF driver shall do that before VF drivers will be loaded. Add function to prepare PTEs. Since it will be used only by the PF driver, make it available only for CONFIG_PCI_IOV=y.

2024-04-16drm/xe: Add helper to format SR-IOV function nameMichal Wajdeczko
While the GuC firmware and the Xe driver are using VF identifier VFID(0) to represent the Physical Function, we should avoid using "VF0" name and use proper "PF" name in all user facing messages related to the Physical Function and use "VFn" name only when referrinf to the true Virtual Function. Add simple helper to get properly formatted function name based on the function number.

2024-04-15drm/xe/gt: Add L3 bank mask to GT topologyFrancois Dugast
Generate the mask of enabled L3 banks for the GT. It is stored with the rest of the GT topology in a consistent representation across platforms. For now the L3 bank mask is just printed in the log for developers to easily figure out the fusing characteristics of machines that they are trying to debug issues on. Later it can be used to replace existing code in the driver that requires the L3 bank count (not mask). Also the mask can easily be exposed to user space in a new query if needed. v2: Better naming of variable and function (Matt Roper) Bspec: 52545, 52546, 62482 Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Francois Dugast <francois.dugast@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240410123723.7-2-francois.dugast@intel.com
2024-04-15drm/nouveau/dp: Don't probe eDP ports twice harderLyude Paul
I didn't pay close enough attention the last time I tried to fix this problem - while we currently do correctly take care to make sure we don't probe a connected eDP port more then once, we don't do the same thing for eDP ports we found to be disconnected. So, fix this and make sure we only ever probe eDP ports once and then leave them at that connector state forever (since without HPD, it's not going to change on its own anyway). This should get rid of the last few GSP errors getting spit out during runtime suspend and resume on some machines, as we tried to reprobe eDP ports in response to ACPI hotplug probe events.
