2022-06-23xhci: turn off port power in shutdownMathias Nyman
If ports are not turned off in shutdown then runtime suspended self-powered USB devices may survive in U3 link state over S5. During subsequent boot, if firmware sends an IPC command to program the port in DISCONNECT state, it will time out, causing significant delay in the boot time. Turning off roothub port power is also recommended in xhci specification 4.19.4 "Port Power" in the additional note.

2022-06-23xhci: Keep interrupt disabled in initialization until host is running.Hongyu Xie
irq is disabled in xhci_quiesce(called by xhci_halt, with bit:2 cleared in USBCMD register), but xhci_run(called by usb_add_hcd) re-enable it. It's possible that you will receive thousands of interrupt requests after initialization for 2.0 roothub. And you will get a lot of warning like, "xHCI dying, ignoring interrupt. Shouldn't IRQs be disabled?". This amount of interrupt requests will cause the entire system to freeze. This problem was first found on a device with ASM2142 host controller on it.

2022-06-23xen/gntdev: Avoid blocking in unmap_grant_pages()Demi Marie Obenour
unmap_grant_pages() currently waits for the pages to no longer be used. In https://github.com/QubesOS/qubes-issues/issues/7481, this lead to a deadlock against i915: i915 was waiting for gntdev's MMU notifier to finish, while gntdev was waiting for i915 to free its pages. I also believe this is responsible for various deadlocks I have experienced in the past. Avoid these problems by making unmap_grant_pages async. This requires making it return void, as any errors will not be available when the function returns. Fortunately, the only use of the return value is a WARN_ON(), which can be replaced by a WARN_ON when the error is detected. Additionally, a failed call will not prevent further calls from being made, but this is harmless. Because unmap_grant_pages is now async, the grant handle will be sent to INVALID_GRANT_HANDLE too late to prevent multiple unmaps of the same handle. Instead, a separate bool array is allocated for this purpose. This wastes memory, but stuffing this information in padding bytes is too fragile. Furthermore, it is necessary to grab a reference to the map before making the asynchronous call, and release the reference when the call returns. It is also necessary to guard against reentrancy in gntdev_map_put(), and to handle the case where userspace tries to map a mapping whose contents have not all been freed yet.

The following sequence currently causes a driver bug warning when using virtio_net: # ip link set eth0 up # echo mem > /sys/power/state (or e.g. # rtcwake -s 10 -m mem) <resume> # ip link set eth0 down Missing register, driver bug WARNING: CPU: 0 PID: 375 at net/core/xdp.c:138 xdp_rxq_info_unreg+0x58/0x60 Call trace: xdp_rxq_info_unreg+0x58/0x60 virtnet_close+0x58/0xac __dev_close_many+0xac/0x140 __dev_change_flags+0xd8/0x210 dev_change_flags+0x24/0x64 do_setlink+0x230/0xdd0 ... This happens because virtnet_freeze() frees the receive_queue completely (including struct xdp_rxq_info) but does not call xdp_rxq_info_unreg(). Similarly, virtnet_restore() sets up the receive_queue again but does not call xdp_rxq_info_reg(). Actually, parts of virtnet_freeze_down() and virtnet_restore_up() are almost identical to virtnet_close() and virtnet_open(): only the calls to xdp_rxq_info_(un)reg() are missing. This means that we can fix this easily and avoid such problems in the future by just calling virtnet_close()/open() from the freeze/restore handlers. Aside from adding the missing xdp_rxq_info calls the only difference is that the refill work is only cancelled if netif_running(). However, this should not make any functional difference since the refill work should only be active if the network interface is actually up.

2022-06-22igb: Make DMA faster when CPU is active on the PCIe linkKai-Heng Feng
Intel I210 on some Intel Alder Lake platforms can only achieve ~750Mbps Tx speed via iperf. The RR2DCDELAY shows around 0x2xxx DMA delay, which will be significantly lower when 1) ASPM is disabled or 2) SoC package c-state stays above PC3. When the RR2DCDELAY is around 0x1xxx the Tx speed can reach to ~950Mbps. According to the I210 datasheet "8.26.1 PCIe Misc. Register - PCIEMISC", "DMA Idle Indication" doesn't seem to tie to DMA coalesce anymore, so set it to 1b for "DMA is considered idle when there is no Rx or Tx AND when there are no TLPs indicating that CPU is active detected on the PCIe link (such as the host executes CSR or Configuration register read or write operation)" and performing Tx should also fall under "active CPU on PCIe link" case. In addition to that, commit b6e0c419f040 ("igb: Move DMA Coalescing init code to separate function.") seems to wrongly changed from enabling E1000_PCIEMISC_LX_DECISION to disabling it, also fix that.

It was discovered that the Documentation lacks of a fundamental detail on how to correctly change the MAX_FRAME_SIZE of the switch. In fact if the MAX_FRAME_SIZE is changed while the cpu port is on, the switch panics and cease to send any packet. This cause the mgmt ethernet system to not receive any packet (the slow fallback still works) and makes the device not reachable. To recover from this a switch reset is required. To correctly handle this, turn off the cpu ports before changing the MAX_FRAME_SIZE and turn on again after the value is applied.

Re-do what was attempted in commit 7a5c922377b4 ("drm/i915/gt: Split intel-gtt functions by arch"). The goal of that commit was to split the handlers for older hardware that depend on intel-gtt.ko so i915 can be built for non-x86 archs, after some more patches. Other archs do not need intel-gtt.ko. Main issue with the previous approach: it moved all the hooks, including the gen8, which is used by all platforms gen8 and newer. Re-do the split moving only the handlers for gen < 6, which are the only ones calling out to the separate module. While at it do some minor cleanups: - Rename the prefix s/gen5_/gmch_/ to be more accurate what platforms are covered by intel_ggtt_gmch.c - Remove dead code for gen12 out of needs_idle_maps() - Remove TODO comment leftover - Re-order if/else ladder in ggtt_probe_hw() to keep newest platforms first v2: Add minor cleanups (Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220617230559.2109427-2-lucas.demarchi@intel.com

2022-06-22drm/amdgpu: Adjust logic around GTT size (v3)Alex Deucher
Certain GL unit tests for large textures can cause problems with the OOM killer since there is no way to link this memory to a process. This was originally mitigated (but not necessarily eliminated) by limiting the GTT size. The problem is this limit is often too low for many modern games so just make the limit 1/2 of system memory. The OOM accounting needs to be addressed, but we shouldn't prevent common 3D applications from being usable just to potentially mitigate that corner case. Set default GTT size to max(3G, 1/2 of system ram) by default. v2: drop previous logic and default to 3/4 of ram v3: default to half of ram to align with ttm v4: fix spelling in comment (Kent) Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1942 Reviewed-by: Marek Olšák <marek.olsak@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-06-22hinic: Replace memcpy() with direct assignmentKees Cook
Under CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y, Clang is bugged here for calculating the size of the destination buffer (0x10 instead of 0x14). This copy is a fixed size (sizeof(struct fw_section_info_st)), with the source and dest being struct fw_section_info_st, so the memcpy should be safe, assuming the index is within bounds, which is UBSAN_BOUNDS's responsibility to figure out. Avoid the whole thing and just do a direct assignment. This results in no change to the executable code.
