Hmm, I guess 64K pages might make a difference in that we'll chew through IOVA space a lot faster with small mappings... I'll have to try to reproduce this locally, since the interesting thing would be knowing what DMA address it was trying to use that went wrong, but IOMMU tracepoints and/or dma-debug are going to generate an crazy amount of data to sift through and try to correlate - having done it before it's not something I'd readily ask someone else to do for me :) On a hunch, though, does it make any difference if you remove the first entry from the PCIe "dma-ranges" (the 0x2c1c0000 one)?

[PATCH v3] mmc: core: Add a card quirk for non-hw busy detection

by Linus Walleij

Some boot partitions on the Samsung 4GB KLM4G1YE4C "4YMD1R" and "M4G1YC" cards appear broken when accessed randomly. CMD6 to switch back to the main partition randomly stalls after CMD18 access to the boot partition 1, and the card never comes back online. The accesses to the boot partitions work several times before this happens, but eventually the card access hangs while initializing the card. Some problematic eMMC cards are found in the Samsung GT-S7710 (Skomer) and SGH-I407 (Kyle) mobile phones. I tried using only single blocks with CMD17 on the boot partitions with the result that it crashed even faster. After a bit of root cause analysis it turns out that these old eMMC cards probably cannot do hardware busy detection (monitoring DAT0) properly. The card survives on older kernels, but this is because recent kernels have added busy detection handling for the SoC used in these phones, exposing the issue. Construct a quirk that makes the MMC cord avoid using the ->card_busy() callback if the card is listed with MMC_QUIRK_BROKEN_HW_BUSY_DETECT and register the known problematic cards. The core changes are pretty straight-forward with a helper inline to check of we can use hardware busy detection. On the MMCI host we have to counter the fact that if the host was able to use busy detect, it would be used unsolicited in the command IRQ callback. Rewrite this so that MMCI will not attempt to use hardware busy detection in the command IRQ until: - A card is attached to the host and - We know that the card can handle this busy detection I have glanced over the ->card_busy() callbacks on some other hosts and they seem to mostly read a register reflecting the value of DAT0 for this which works fine with the quirk in this patch. However if the error appear on other hosts they might need additional fixes. After applying this patch, the main partition can be accessed and mounted without problems on Samsung GT-S7710 and SGH-I407.

[PATCH 1/1] KVM: s390: index kvm->arch.idle_mask by vcpu_idx

by Halil Pasic

While in practice vcpu->vcpu_idx == vcpu->vcp_id is often true, it may not always be, and we must not rely on this. Currently kvm->arch.idle_mask is indexed by vcpu_id, which implies that code like for_each_set_bit(vcpu_id, kvm->arch.idle_mask, online_vcpus) { vcpu = kvm_get_vcpu(kvm, vcpu_id); do_stuff(vcpu); } is not legit. The trouble is, we do actually use kvm->arch.idle_mask like this. To fix this problem we have two options. Either use kvm_get_vcpu_by_id(vcpu_id), which would loop to find the right vcpu_id, or switch to indexing via vcpu_idx. The latter is preferable for obvious reasons. Let us make switch from indexing kvm->arch.idle_mask by vcpu_id to indexing it by vcpu_idx. To keep gisa_int.kicked_mask indexed by the same index as idle_mask lets make the same change for it as well.

[PATCH] gpio: dln2: Fix interrupts when replugging the device

by Noralf Trønnes

When replugging the device the following message shows up: gpio gpiochip2: (dln2): detected irqchip that is shared with multiple gpiochips: please fix the driver. This also has the effect that interrupts won't work. The same problem would also show up if multiple devices where plugged in. Fix this by allocating the irq_chip data structure per instance like other drivers do. I don't know when this problem appeared, but it is present in 5.10.

Thanks, I squashed the fix in. HOWEVER, I think it would be fairly risky to push this into v5.15. We would be relying on the assumption that current machines have all fixed the BIOS defect that 4dc2287c1805 addressed, and we have little evidence for that. I'm not sure there's significant benefit to having this in v5.15. Yes, the mainline v5.15 kernel would work on the affected machines, but I suspect most people with those machines are running distro kernels, not mainline kernels. This issue has been around a long time, so it's not like a regression that we just introduced. If we fixed these machines and regressed *other* machines, we'd be worse off than we are now. Convince me otherwise if you see this differently :) In the meantime, here's another possibility for working around this. What if we discarded remove_e820_regions() completely, but aligned the problem _CRS windows a little more? The 4dc2287c1805 case was this: BIOS-e820: 00000000bfe4dc00 - 00000000c0000000 (reserved) pci_root PNP0A03:00: host bridge window [mem 0xbff00000-0xdfffffff] where the _CRS window was of size 0x20100000, i.e., 512M + 1M. At least in this particular case, we could avoid the problem by throwing away that first 1M and aligning the window to a nice 3G boundary. Maybe it would be worth giving up a small fraction (less than 0.2% in this case) of questionable windows like this? Bjorn
