| 2014-04-04 | tile: Fix vDSO compilation issue with allyesconfig | Kerry Sheh | |
| make allyesconfig give the following build error on tile: tilegx-linux-gcc: error: arch/tile/kernel/vdso/vgettimeofday32.o: No such file or directory tilegx-linux-objcopy: 'arch/tile/kernel/vdso/vdso32.so.dbg': No such file or directory In case with CONFIG_MODVERSIONS, cmd_cc_o_c generate .tmp_<file>.o from <file>.c only. Fix it by execute rule_cc_o_c instead. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Kerry Sheh <ksheh@tilera.com> Signed-off-by: Chris Metcalf <cmetcalf@tilera.com> | |||
| 2013-08-13 | tile: implement gettimeofday() via vDSO | Chris Metcalf | |
| This change creates the framework for vDSO calls, makes the existing rt_sigreturn() mechanism use it, and adds a fast gettimeofday(). Now that we need to expose the vDSO address to userspace, we add AT_SYSINFO_EHDR to the set of aux entries provided to userspace. (You can disable any extra vDSO support by booting with vdso=0, but the rt_sigreturn vDSO page will still be provided.) Note that glibc has supported the tile vDSO since release 2.17.
