Hi Dmitry, When trying to test the series under Linux (RedHat 7.4, x86_64-native-linuxapp-gcc) I get compilation errors. I am using make. It seems that there are calls from common which are not compiled under linux.
x86_64-native-linuxapp-gcc/lib/librte_eal.a(eal_common_memory.o): In function `eal_get_virtual_area': eal_common_memory.c:(.text+0x27e): undefined reference to `eal_mem_reserve' [dpdk-branches]$ find lib -name '*.c' | xargs grep eal_mem_reserve lib/librte_eal/common/eal_common_memory.c: mapped_addr = eal_mem_reserve( lib/librte_eal/windows/eal_memory.c:eal_mem_reserve(void *requested_addr, size_t size, lib/librte_eal/unix/eal_memory.c:eal_mem_reserve(void *requested_addr, size_t size, Does it succeed for you? If not - can you please resend the series such that it compiles under Linux with Makefile? > -----Original Message----- > From: dev <dev-boun...@dpdk.org> On Behalf Of Dmitry Kozlyuk > Sent: Tuesday, April 14, 2020 10:44 PM > To: dev@dpdk.org > Cc: Dmitry Malloy (MESHCHANINOV) <dmit...@microsoft.com>; Narcisa > Ana Maria Vasile <narcisa.vas...@microsoft.com>; Fady Bader > <f...@mellanox.com>; Tal Shnaiderman <tal...@mellanox.com>; Dmitry > Kozlyuk <dmitry.kozl...@gmail.com>; Ranjit Menon > <ranjit.me...@intel.com> > Subject: [dpdk-dev] [PATCH v3 1/1] virt2phys: virtual to physical address > translator for Windows > > This driver supports Windows EAL memory management by translating > current process virtual addresses to physical addresses (IOVA). > Standalone virt2phys allows using DPDK without PMD and provides a > reference implementation. > > Suggested-by: Ranjit Menon <ranjit.me...@intel.com> > Signed-off-by: Dmitry Kozlyuk <dmitry.kozl...@gmail.com> > --- > windows/README.rst | 103 +++++++++ > windows/virt2phys/virt2phys.c | 129 +++++++++++ > windows/virt2phys/virt2phys.h | 34 +++ > windows/virt2phys/virt2phys.inf | 64 ++++++ > windows/virt2phys/virt2phys.sln | 27 +++ > windows/virt2phys/virt2phys.vcxproj | 228 ++++++++++++++++++++ > windows/virt2phys/virt2phys.vcxproj.filters | 36 ++++ > 7 files changed, 621 insertions(+) > create mode 100644 windows/README.rst > create mode 100644 windows/virt2phys/virt2phys.c create mode 100644 > windows/virt2phys/virt2phys.h create mode 100644 > windows/virt2phys/virt2phys.inf create mode 100644 > windows/virt2phys/virt2phys.sln create mode 100644 > windows/virt2phys/virt2phys.vcxproj > create mode 100644 windows/virt2phys/virt2phys.vcxproj.filters > > diff --git a/windows/README.rst b/windows/README.rst new file mode > 100644 index 0000000..45a1d80 > --- /dev/null > +++ b/windows/README.rst > @@ -0,0 +1,103 @@ > +Developing Windows Drivers > +========================== > + > +Prerequisites > +------------- > + > +Building Windows Drivers is only possible on Windows. > + > +1.
