| | * | | fpga: dfl: fme: add DFL_FPGA_FME_PORT_RELEASE/ASSIGN ioctl support.Wu Hao2019-08-053-12/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to support virtualization usage via PCIe SRIOV, this patch adds two ioctls under FPGA Management Engine (FME) to release and assign back the port device. In order to safely turn Port from PF into VF and enable PCIe SRIOV, it requires user to invoke this PORT_RELEASE ioctl to release port firstly to remove userspace interfaces, and then configure the PF/VF access register in FME. After disable SRIOV, it requires user to invoke this PORT_ASSIGN ioctl to attach the port back to PF. Ioctl interfaces: * DFL_FPGA_FME_PORT_RELEASE Release platform device of given port, it deletes port platform device to remove related userspace interfaces on PF. After this function, then it's safe to configure PF/VF access mode to VF, and enable VFs via SRIOV. * DFL_FPGA_FME_PORT_ASSIGN Assign platform device of given port back to PF. After configure PF/VF access mode to PF, this ioctl adds port platform device back to re-enable related userspace interfaces on PF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current driver checks if input bitstream file size is aligned or not per PR data width (default 32bits). It requires one additional step for end user when they generate the bitstream file, padding extra zeros to bitstream file to align its size per PR data width, but they don't have to as hardware will drop extra padding bytes automatically. In order to simplify the user steps, this patch aligns PR buffer size per PR data width in driver, to allow user to pass unaligned size bitstream files to driver.

This patch does not change any functionality. New functionality will follow in subsequent patches. Some of the get_user_pages_fast() call sites were unchanged because they already passed FOLL_WRITE or 0 for the write parameter. NOTE: It was suggested to change the ordering of the get_user_pages_fast() arguments to ensure that callers were converted. This breaks the current GUP call site convention of having the returned pages be the final parameter. So the suggestion was rejected.

* Remove 'type' argument from access_ok() functionLinus Torvalds2019-01-042-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <[email protected]>

* fpga: mgr: altera-ps-spi: enable usage on non-dt platformsAnatolij Gustschin2018-11-261-5/+35
| | | | | | | | | | | | | | Driver probing fails on non-dt platforms since of_match_device() always returns NULL here. Add spi ids with device names and matching driver data as an index of a map array with data for supported devices. Add this map array and a function for mapping spi ids to driver data. This allows driver binding to dynamically added PS-SPI devices (e.g. when added via spi_new_device() after hot-plugging).

* zynq-fpga: Only route PR via PCAP when requiredMike Looijmans2018-11-111-0/+4
| | | | | | | | | | | | | | | The Xilinx Zynq FPGA driver takes ownership of the PR interface, making it impossible to use the ICAP interface for partial reconfiguration. This patch changes the driver to only activate PR over PCAP while the device is actively being accessed by the driver for programming. This allows both PCAP and ICAP interfaces to be used for PR.
