2022-03-16drm/i915: fixup the initial fb base on DGFXMatthew Auld1-6/+44
On integrated it looks like the GGTT base should always 1:1 maps to somewhere within DSM. On discrete the base seems to be pre-programmed with a normal lmem address, and is not 1:1 mapped with the base address. On such devices probe the lmem address directly from the PTE. v2(Ville): - The base is actually the pre-programmed GGTT address, which is then meant to 1:1 map to somewhere inside dsm. In the case of dgpu the base looks to just be some offset within lmem, but this also happens to be the exact dsm start, on dg1. Therefore we should only need to fudge the physical address, before allocating from stolen. - Bail if it's not located in dsm. v3: - Scratch that. There doesn't seem to be any relationship with the base and PTE address, on at least DG1. Let's instead just grab the lmem address from the PTE itself.

When system does not have mappable aperture, ggtt->mappable_end=0. In this case if we pass PIN_MAPPABLE when pinning vma, the pinning code will return -ENOSPC. So conditionally set PIN_MAPPABLE if HAS_GMCH().

2022-03-16drm/i915/stolen: don't treat small BAR as an errorAkeem G Abodunrin2-19/+46
On client platforms with reduced LMEM BAR, we should be able to continue with driver load with reduced io_size. Instead of using the BAR size to determine the how large stolen should be, we should instead use the ADDR_RANGE register to figure this out(at least on platforms like DG2). For simplicity we don't attempt to support partially mappable stolen. v2: rearrange the io_mapping_init_wc slightly, since the stolen setup might result in reduced io_size.

2022-03-16ice: add trace events for tx timestampsJacob Keller2-0/+32
We've previously run into many issues related to the latency of a Tx timestamp completion with the ice hardware. It can be difficult to determine the root cause of a slow Tx timestamp. To aid in this, introduce new trace events which capture timing data about when the driver reaches certain points while processing a transmit timestamp * ice_tx_tstamp_request: Trace when the stack initiates a new timestamp request. * ice_tx_tstamp_fw_req: Trace when the driver begins a read of the timestamp register in the work thread. * ice_tx_tstamp_fw_done: Trace when the driver finishes reading a timestamp register in the work thread. * ice_tx_tstamp_complete: Trace when the driver submits the skb back to the stack with a completed Tx timestamp. These trace events can be enabled using the standard trace event subsystem exposed by the ice driver. If they are disabled, they become no-ops with no run time cost. The following is a simple GNU AWK script which can highlight one potential way to use the trace events to capture latency data from the trace buffer about how long the driver takes to process a timestamp: ----- BEGIN { PREC=256 } # Detect requests /tx_tstamp_request/ { time=strtonum($4) skb=$7 # Store the time of request for this skb requests[skb] = time printf("skb %s: idx %d at %.6f\n", skb, idx, time) } # Detect completions /tx_tstamp_complete/ { time=strtonum($4) skb=$7 idx=$9 if (skb in requests) { latency = (time - requests[skb]) * 1000 printf("skb %s: %.3f to complete\n", skb, latency) if (latency > 4) { printf(">>> HIGH LATENCY <<<\n") } printf("\n") } else { printf("!!! skb %s (idx %d) at %.6f\n", skb, idx, time) } } ----- Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Gurucharan <gurucharanx.g@intel.com> (A Contingent worker at Intel) Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
