With this .config: http://busybox.net/~vda/kernel_config, after uninlining these functions have sizes and callsite counts as follows: __OUTPLLP: 61 bytes, 12 callsites __INPLL: 79 bytes, 150 callsites __OUTPLL: 82 bytes, 138 callsites _OUTREGP: 101 bytes, 8 callsites _radeon_msleep: 66 bytes, 18 callsites _radeon_fifo_wait: 83 bytes, 24 callsites _radeon_engine_idle: 92 bytes, 10 callsites radeon_engine_flush: 105 bytes, 2 callsites radeon_pll_errata_after_index_slow: 31 bytes, 11 callsites radeon_pll_errata_after_data_slow: 91 bytes, 9 callsites radeon_pll_errata_after_FOO functions are split into two parts: the inlined part which checks corresponding rinfo->errata bit, and out-of-line part which performs workaround magic per se. Reduction in code size is about 49,500 bytes: text data bss dec hex filename 85789648 22294616 20627456 128711720 7abfc28 vmlinux.before 85740176 22294680 20627456 128662312 7ab3b28 vmlinux Signed-off-by: Denys Vlasenko <dvlasenk@redhat.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: David Airlie <airlied@linux.ie> Cc: Alex Deucher <alexdeucher@gmail.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Zhang Rui <rui.zhang@intel.com> Cc: Len Brown <lenb@kernel.org> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: Dave Airlie <airlied@redhat.com> Cc: linux-kernel@vger.kernel.org Cc: linux-fbdev@vger.kernel.org Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> |
