[PATCH v2] mm/shmem: Fix race in shmem_undo_range w/THP

by David Stevens

From: David Stevens <stevensd(a)chromium.org> Split folios during the second loop of shmem_undo_range. It's not sufficient to only split folios when dealing with partial pages, since it's possible for a THP to be faulted in after that point. Calling truncate_inode_folio in that situation can result in throwing away data outside of the range being targeted. Fixes: b9a8a4195c7d ("truncate,shmem: Handle truncates that split large folios") Cc: stable(a)vger.kernel.org Signed-off-by: David Stevens <stevensd(a)chromium.org> --- v1 -> v2: - Actually drop pages after splitting a THP mm/shmem.c | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) diff --git a/mm/shmem.c b/mm/shmem.c index 9218c955f482..226c94a257b1 100644 --- a/mm/shmem.c +++ b/mm/shmem.c @@ -1033,7 +1033,22 @@ static void shmem_undo_range(struct inode *inode, loff_t lstart, loff_t lend, } VM_BUG_ON_FOLIO(folio_test_writeback(folio), folio); - truncate_inode_folio(mapping, folio); + + if (!folio_test_large(folio)) { + truncate_inode_folio(mapping, folio); + } else if (truncate_inode_partial_folio(folio, lstart, lend)) { + /* + * If we split a page, reset the loop so that we + * pick up the new sub pages.

[PATCH] mm/shmem: Fix race in shmem_undo_range w/THP

by David Stevens

From: David Stevens <stevensd(a)chromium.org> Split folios during the second loop of shmem_undo_range. It's not sufficient to only split folios when dealing with partial pages, since it's possible for a THP to be faulted in after that point. Calling truncate_inode_folio in that situation can result in throwing away data outside of the range being targeted.

[PATCH v5 10/11] PCI: rockchip: Don't advertise MSI-X in PCIe capabilities

by Rick Wertenbroek

The RK3399 PCIe endpoint controller cannot generate MSI-X IRQs. This is documented in the RK3399 technical reference manual (TRM) section 17.5.9 "Interrupt Support". MSI-X capability should therefore not be advertised. Remove the MSI-X capability by editing the capability linked-list. The previous entry is the MSI capability, therefore get the next entry from the MSI-X capability entry and set it as next entry for the MSI capability. This in effect removes MSI-X from the list. Linked list before : MSI cap -> MSI-X cap -> PCIe Device cap -> ... Linked list now : MSI cap -> PCIe Device cap -> ...

[PATCH v5 08/11] PCI: rockchip: Fix window mapping and address translation for endpoint

by Rick Wertenbroek

The RK3399 PCI endpoint core has 33 windows for PCIe space, now in the driver up to 32 fixed size (1M) windows are used and pages are allocated and mapped accordingly. The driver first used a single window and allocated space inside which caused translation issues (between CPU space and PCI space) because a window can only have a single translation at a given time, which if multiple pages are allocated inside will cause conflicts. Now each window is a single region of 1M which will always guarantee that the translation is not in conflict. Set the translation register addresses for physical function. As documented in the technical reference manual (TRM) section 17.5.5 "PCIe Address Translation" and section 17.6.8 "Address Translation Registers Description" Fixes: cf590b078391 ("PCI: rockchip: Add EP driver for Rockchip PCIe controller") Cc: stable(a)vger.kernel.org Tested-by: Damien Le Moal <dlemoal(a)kernel.org> Reviewed-by: Damien Le Moal <dlemoal(a)kernel.org> Signed-off-by: Rick Wertenbroek <rick.wertenbroek(a)gmail.com> --- drivers/pci/controller/pcie-rockchip-ep.c | 128 ++++++++++------------ drivers/pci/controller/pcie-rockchip.h | 35 +++--- 2 files changed, 75 insertions(+), 88 deletions(-) diff --git a/drivers/pci/controller/pcie-rockchip-ep.c b/drivers/pci/controller/pcie-rockchip-ep.c index d6d4b0f2e733..771f1bb93251 100644 --- a/drivers/pci/controller/pcie-rockchip-ep.c +++ b/drivers/pci/controller/pcie-rockchip-ep.c @@ -64,52 +64,29 @@ static void rockchip_pcie_clear_ep_ob_atu(struct rockchip_pcie *rockchip, } static void rockchip_pcie_prog_ep_ob_atu(struct rockchip_pcie *rockchip, u8 fn, - u32 r, u32 type, u64 cpu_addr, - u64 pci_addr, size_t size) + u32 r, u64 cpu_addr, u64 pci_addr, + size_t size) { - u64 sz = 1ULL << fls64(size - 1);

[PATCH v5 07/11] PCI: rockchip: Fix legacy IRQ generation for RK3399 PCIe endpoint core

by Rick Wertenbroek

Fix legacy IRQ generation for RK3399 PCIe endpoint core according to the technical reference manual (TRM). Assert and deassert legacy interrupt (INTx) through the legacy interrupt control register ("PCIE_CLIENT_LEGACY_INT_CTRL") instead of manually generating a PCIe message. The generation of the legacy interrupt was tested and validated with the PCIe endpoint test driver.

[PATCH v5 04/11] PCI: rockchip: Add poll and timeout to wait for PHY PLLs to be locked

by Rick Wertenbroek

The RK3399 PCIe controller should wait until the PHY PLLs are locked. Add poll and timeout to wait for PHY PLLs to be locked. If they cannot be locked generate error message and jump to error handler. Accessing registers in the PHY clock domain when PLLs are not locked causes hang The PHY PLLs status is checked through a side channel register. This is documented in the TRM section 17.5.8.1 "PCIe Initialization Sequence".
