This hcall is handled in the host in # kvmppc_h_set_dawr() which can be called in either real mode on the # guest exit path from hcall_try_real_mode() in book3s_hv_rmhandlers.S, # or in virtual mode when called from kvmppc_pseries_do_hcall() in # book3s_hv.c. # # The function kvmppc_h_set_dawr() updates the dawr and dawrx fields in # the vcpu struct accordingly and then also writes the respective values # into the DAWR and DAWRX registers directly. It is necessary to write # the registers directly here when calling the function in real mode # since the path to re-enter the guest won't do this. However when in # virtual mode the host DAWR and DAWRX values have already been # restored, and so writing the registers would overwrite these. # Additionally there is no reason to write the guest values here as # these will be read from the vcpu struct and written to the registers # appropriately the next time the vcpu is run. # # This also avoids the case when handling h_set_dawr for a nested guest # where the guest hypervisor isn't able to write the DAWR and DAWRX # registers directly and must rely on the real hypervisor to do this for # it when it calls H_ENTER_NESTED. # # Fixes: c1fe190c0672 ("powerpc: Add force enable of DAWR on P9 option") # Signed-off-by: Suraj Jitindar Singh <sjitindarsingh@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 84b028243ef07a3f65c1857343ada2b1022f8bed # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ps3_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ps3_defconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ps3_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/genhd.h:67:0, from /kisskb/src/include/linux/blkdev.h:11, from /kisskb/src/drivers/block/ps3vram.c:12: /kisskb/src/drivers/block/ps3vram.c: In function 'ps3vram_probe': /kisskb/src/drivers/block/ps3vram.c:770:23: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'sector_t {aka long long unsigned int}' [-Wformat=] dev_info(&dev->core, "%s: Using %lu MiB of GPU memory\n", ^ /kisskb/src/include/linux/device.h:1400:22: note: in definition of macro 'dev_fmt' #define dev_fmt(fmt) fmt ^ /kisskb/src/drivers/block/ps3vram.c:770:2: note: in expansion of macro 'dev_info' dev_info(&dev->core, "%s: Using %lu MiB of GPU memory\n", ^ WARNING: vmlinux.o(.text+0x322a): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup() The function start_here_multiplatform() references the function __init .early_setup().
