From c1f58f1e1e5596f9377ae8839500f56677b3d0b7 Mon Sep 17 00:00:00 2001 From: Peter Huewe Date: Fri, 4 May 2012 00:14:55 +0200 Subject: [PATCH] video/sis: Annotate SiS_DRAMType as __devinitconst SiS_DRAMType is const and only used by sisfb_post_300_rwtest which is marked __devinit we can annotate SiS_DRAMType with __devinitconst and move it into the file scope in order to not have it created on the stack. This patch decreases the compiled module size by about 100bytes. And since hardcoded values are bad we use ARRAY_SIZE for determining the size of SiS_DRAMType ;) Signed-off-by: Peter Huewe Signed-off-by: Florian Tobias Schandinat --- drivers/video/sis/sis_main.c | 41 ++++++++++++++++++------------------ 1 file changed, 21 insertions(+), 20 deletions(-) diff --git a/drivers/video/sis/sis_main.c b/drivers/video/sis/sis_main.c index 078ca2167d6f..a7a48db64ce2 100644 --- a/drivers/video/sis/sis_main.c +++ b/drivers/video/sis/sis_main.c @@ -4222,6 +4222,26 @@ sisfb_post_300_buswidth(struct sis_video_info *ivideo) return 1; /* 32bit */ } +static const unsigned short __devinitconst SiS_DRAMType[17][5] = { + {0x0C,0x0A,0x02,0x40,0x39}, + {0x0D,0x0A,0x01,0x40,0x48}, + {0x0C,0x09,0x02,0x20,0x35}, + {0x0D,0x09,0x01,0x20,0x44}, + {0x0C,0x08,0x02,0x10,0x31}, + {0x0D,0x08,0x01,0x10,0x40}, + {0x0C,0x0A,0x01,0x20,0x34}, + {0x0C,0x09,0x01,0x08,0x32}, + {0x0B,0x08,0x02,0x08,0x21}, + {0x0C,0x08,0x01,0x08,0x30}, + {0x0A,0x08,0x02,0x04,0x11}, + {0x0B,0x0A,0x01,0x10,0x28}, + {0x09,0x08,0x02,0x02,0x01}, + {0x0B,0x09,0x01,0x08,0x24}, + {0x0B,0x08,0x01,0x04,0x20}, + {0x0A,0x08,0x01,0x02,0x10}, + {0x09,0x08,0x01,0x01,0x00} +}; + static int __devinit sisfb_post_300_rwtest(struct sis_video_info *ivideo, int iteration, int buswidth, int PseudoRankCapacity, int PseudoAdrPinCount, @@ -4231,27 +4251,8 @@ sisfb_post_300_rwtest(struct sis_video_info *ivideo, int iteration, int buswidth unsigned short sr14; unsigned int k, RankCapacity, PageCapacity, BankNumHigh, BankNumMid; unsigned int PhysicalAdrOtherPage, PhysicalAdrHigh, PhysicalAdrHalfPage; - static const unsigned short SiS_DRAMType[17][5] = { - {0x0C,0x0A,0x02,0x40,0x39}, - {0x0D,0x0A,0x01,0x40,0x48}, - {0x0C,0x09,0x02,0x20,0x35}, - {0x0D,0x09,0x01,0x20,0x44}, - {0x0C,0x08,0x02,0x10,0x31}, - {0x0D,0x08,0x01,0x10,0x40}, - {0x0C,0x0A,0x01,0x20,0x34}, - {0x0C,0x09,0x01,0x08,0x32}, - {0x0B,0x08,0x02,0x08,0x21}, - {0x0C,0x08,0x01,0x08,0x30}, - {0x0A,0x08,0x02,0x04,0x11}, - {0x0B,0x0A,0x01,0x10,0x28}, - {0x09,0x08,0x02,0x02,0x01}, - {0x0B,0x09,0x01,0x08,0x24}, - {0x0B,0x08,0x01,0x04,0x20}, - {0x0A,0x08,0x01,0x02,0x10}, - {0x09,0x08,0x01,0x01,0x00} - }; - for(k = 0; k <= 16; k++) { + for(k = 0; k < ARRAY_SIZE(SiS_DRAMType); k++) { RankCapacity = buswidth * SiS_DRAMType[k][3]; -- 2.39.5
