Correct the CLKVAL_F field value of VIDEO MAIN CONTROLLER 0 REGITSTER. Frame Rate is 1 / [ { (VSPW+1) + (VBPD+1) + (LIINEVAL + 1) + (VFPD+1) } x {(HSPW+1) + (HBPD +1) + (HFPD+1) + (HOZVAL + 1) } x { ( CLKVAL+1 ) / ( Frequency of Clock source ) } ] and VCLK = Video Clock Source / (CLKVAL +1). therefore CLKVAL_F should be "CLKVAL_F = Frequency of Clock source / pixel clock * refresh". for this, I added refresh value in platform data like below. static struct s3c_fb_pd_win xxx_fb_win0 = { /* this is to ensure we use win0 */ .win_mode = { .refresh = 60, .pixclock = (66+4+2+480)*(15+5+3+800), .left_margin = 66, .right_margin = 2, .upper_margin = 15, .lower_margin = 3, .hsync_len = 4, .vsync_len = 5, .xres = 480, .yres = 800, }, .max_bpp = 32, .default_bpp = 24, }; static struct s3c_fb_platdata xxx_lcd_pdata __initdata = { .win[0] = &xxx_fb_win0, .vidcon0 = VIDCON0_VIDOUT_RGB | VIDCON0_PNRMODE_RGB, .vidcon1 = VIDCON1_INV_HSYNC | VIDCON1_INV_VSYNC | VIDCON1_INV_VCLK | VIDCON1_INV_VDEN, .setup_gpio = s5pc1xx_fb_gpio_setup_24bpp, }; xxx_machine_init() { . . . s3c_fb_set_platdata(&xxx_lcd_pdata); } platform data defined in machine code should be setting using s3c_fb_set_platdata().

2009-07-06mm: mark page accessed before we write_end()Josef Bacik1-0/+1
In testing a backport of the write_begin/write_end AOPs, a 10% re-read regression was noticed when running iozone. This regression was introduced because the old AOPs would always do a mark_page_accessed(page) after the commit_write, but when the new AOPs where introduced, the only place this was kept was in pagecache_write_end(). This patch does the same thing in the generic case as what is done in pagecache_write_end(), which is just to mark the page accessed before we do write_end().

2009-07-06elf: fix multithreaded program core dumping on armHui Zhu1-0/+2
Fix the multithread program core thread message error. This issue affects arches with neither has CORE_DUMP_USE_REGSET nor ELF_CORE_COPY_TASK_REGS, ARM is one of them. The thread message of core file is generated in elf_dump_thread_status. The register values is set by elf_core_copy_task_regs in this function. If an arch doesn't define ELF_CORE_COPY_TASK_REGS, elf_core_copy_task_regs() will do nothing. Then the core file will not have the register message of thread. So add elf_core_copy_regs to set regiser values if ELF_CORE_COPY_TASK_REGS doesn't define. The following is how to reproduce this issue: cat 1.c #include <stdio.h> #include <pthread.h> #include <assert.h> void td1(void * i) { while (1) { printf ("1\n"); sleep (1); } return; } void td2(void * i) { while (1) { printf ("2\n"); sleep (1); } return; } int main(int argc,char *argv[],char *envp[]) { pthread_t t1,t2; pthread_create(&t1, NULL, (void*)td1, NULL); pthread_create(&t2, NULL, (void*)td2, NULL); sleep (10); assert(0); return (0); } arm-xxx-gcc -g -lpthread 1.c -o 1 copy 1.c and 1 to a arm board. Goto this board. ulimit -c 1800000 ./1 # ./1 1 2 1 ... ... 1 1: 1.c:37: main: Assertion `0' failed.

2009-07-06sys_sync(): fix 16% performance regression in ffsb create_4k testZhang, Yanmin1-0/+5
I run many ffsb test cases on JBODs (typically 13/12 disks). Comparing with kernel 2.6.30, 2.6.31-rc1 has about 16% regression with ffsb_create_4k. The sub test case creates files continuously for 10 minitues and every file is 1MB. Bisect located below patch. 5cee5815d1564bbbd505fea86f4550f1efdb5cd0 is first bad commit commit 5cee5815d1564bbbd505fea86f4550f1efdb5cd0 Author: Jan Kara <[email protected]> Date: Mon Apr 27 16:43:51 2009 +0200 vfs: Make sys_sync() use fsync_super() (version 4) It is unnecessarily fragile to have two places (fsync_super() and do_sync()) doing data integrity sync of the filesystem. Alter __fsync_super() to accommodate needs of both callers and use it. So after this patch __fsync_super() is the only place where we gather all the calls needed to properly send all data on a filesystem to disk. As a matter of fact, ffsb calls sys_sync in the end to make sure all data is flushed to disks and the flushing is counted into the result. vmstat shows ffsb is blocked when syncing for a long time. With 2.6.30, ffsb is blocked for a short time. I checked the patch and did experiments to recover the original methods. Eventually, the root cause is the patch deletes the calling to wakeup_pdflush when syncing, so only ffsb is blocked on disk I/O. wakeup_pdflush could ask pdflush to write back pages with ffsb at the same time.

2009-07-06microblaze: convert all simple headers to use asm-genericRemis Lima Baima19-266/+21
All the simple microblaze header files were adapted to use their asm-generic implementations. These files are more simple and were quite straightforward to change. fb.h, vga.h and parport.h previously did not exist, using the generic version makes it possible to build more drivers successfully in allyesonfig.

2009-07-05drivers/net/smsc911x.c: Fix resource size off by 1 errorJulia Lawall1-3/+3
The call resource_size(res) returns res->end - res->start + 1 and thus the second change is semantics-preserving. res_size is then used as the second argument of a call to request_mem_region, and the memory allocated by this call appears to be the same as what is released in the two calls to release_mem_region. So the size argument for those calls should be resource_size(size) as well. Alternatively, in the second call to release_mem_region, the second argument could be res_size, as that variable has already been initialized at the point of this call. The problem was found using the following semantic patch: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) @@ struct resource *res; @@ - res->end - res->start + BAD(resource_size(res)) // </smpl> Signed-off-by: Julia Lawall <[email protected]> Signed-off-by: David S.

2009-07-05tun: Fix device unregister raceHerbert Xu1-7/+9
It is currently possible for an asynchronous device unregister to cause the same tun device to be unregistered twice. This is because the unregister in tun_chr_close only checks whether __tun_get(tfile) != NULL. This however has nothing to do with whether the device has already been unregistered. All it tells you is whether __tun_detach has been called. This patch fixes this by using the most obvious thing to test whether the device has been unregistered. It also moves __tun_detach outside of rtnl_unlock since nothing that it does requires that lock. Signed-off-by: Herbert Xu <[email protected]> Signed-off-by: David S. Miller <[email protected]>

The loop iteration should have set $prevlen = $currlen at the end of the loop, and the if() check should have used && instead of || for deciding if the firmware length is reasonable.

version) Fix the code so that the zl10353 version of the Terratec Cinergy T XS USB starts working again. This includes fixing what must have been a typo in the GPIO definition for the digital side of the board, and setting of the disable_i2c_gate_ctrl property for the zl10353 config, so that the i2c bus doesn't get wedged the first time something tries to close the gate. Also, add a printk() making clear that the mt352 version still isn't supported. This issue is still being actively debugged, but in the meantime at least the dmesg output will show a very clear error... Thanks to Jelle de Jong for providing sample hardware to test with. Thanks to Simon Kenyon for testing various patches and providing SSH access to his environment so I could debug with access to a valid signal source.
