From 890be2bb55774290479672b98fcb0486b57e758e Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 7 Jun 2007 08:10:41 -0300 Subject: [PATCH] V4L/DVB (5774a): Remove CONFIG_BIGPHYS_AREA from zoran_driver CONFIG_BIGPHYS_AREA is an out-of-tree kernel patch. It makes no sense to keep supporting this on mainstream. The out-of-tree compilation with CONFIG_BIGPHYS_AREA will still be preserved at the v4l-dvb development tree at: http://linuxtv.org/hg/v4l-dvb Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/zoran_driver.c | 63 -------------------------------------- 1 file changed, 63 deletions(-) diff --git a/drivers/media/video/zoran_driver.c b/drivers/media/video/zoran_driver.c index cf0ed6cbb0e..17118a490f8 100644 --- a/drivers/media/video/zoran_driver.c +++ b/drivers/media/video/zoran_driver.c @@ -183,14 +183,7 @@ static const int zoran_num_formats = (sizeof(zoran_formats) / sizeof(struct zoran_format)); // RJ: Test only - want to test BUZ_USE_HIMEM even when CONFIG_BIGPHYS_AREA is defined -#if !defined(CONFIG_BIGPHYS_AREA) -//#undef CONFIG_BIGPHYS_AREA -#define BUZ_USE_HIMEM -#endif -#if defined(CONFIG_BIGPHYS_AREA) -# include -#endif extern int *zr_debug; @@ -250,7 +243,6 @@ static void jpg_fbuffer_free(struct file *file); * Linux with the necessary memory left over). */ -#if defined(BUZ_USE_HIMEM) && !defined(CONFIG_BIGPHYS_AREA) static unsigned long get_high_mem (unsigned long size) { @@ -314,7 +306,6 @@ get_high_mem (unsigned long size) return hi_mem_ph; } -#endif static int v4l_fbuffer_alloc (struct file *file) @@ -323,9 +314,7 @@ v4l_fbuffer_alloc (struct file *file) struct zoran *zr = fh->zr; int i, off; unsigned char *mem; -#if defined(BUZ_USE_HIMEM) && !defined(CONFIG_BIGPHYS_AREA) unsigned long pmem = 0; -#endif /* we might have old buffers lying around... */ if (fh->v4l_buffers.ready_to_be_freed) { @@ -369,39 +358,6 @@ v4l_fbuffer_alloc (struct file *file) ZR_DEVNAME(zr), i, (unsigned long) mem, virt_to_bus(mem)); } else { -#if defined(CONFIG_BIGPHYS_AREA) - /* Use bigphysarea_alloc_pages */ - - int n = - (fh->v4l_buffers.buffer_size + PAGE_SIZE - - 1) / PAGE_SIZE; - - mem = - (unsigned char *) bigphysarea_alloc_pages(n, 0, - GFP_KERNEL); - if (mem == 0) { - dprintk(1, - KERN_ERR - "%s: v4l_fbuffer_alloc() - bigphysarea_alloc_pages for V4L buf %d failed\n", - ZR_DEVNAME(zr), i); - v4l_fbuffer_free(file); - return -ENOBUFS; - } - fh->v4l_buffers.buffer[i].fbuffer = mem; - fh->v4l_buffers.buffer[i].fbuffer_phys = - virt_to_phys(mem); - fh->v4l_buffers.buffer[i].fbuffer_bus = - virt_to_bus(mem); - dprintk(4, - KERN_INFO - "%s: Bigphysarea frame %d mem 0x%x (bus: 0x%x)\n", - ZR_DEVNAME(zr), i, (unsigned) mem, - (unsigned) virt_to_bus(mem)); - - /* Zero out the allocated memory */ - memset(fh->v4l_buffers.buffer[i].fbuffer, 0, - fh->v4l_buffers.buffer_size); -#elif defined(BUZ_USE_HIMEM) /* Use high memory which has been left at boot time */ @@ -441,20 +397,6 @@ v4l_fbuffer_alloc (struct file *file) fh->v4l_buffers.buffer[i].fbuffer_bus = pmem + i * fh->v4l_buffers.buffer_size; } -#else - /* No bigphysarea present, usage of high memory disabled, - * but user wants buffers of more than MAX_KMALLOC_MEM */ - dprintk(1, - KERN_ERR - "%s: v4l_fbuffer_alloc() - no bigphysarea_patch present, usage of high memory disabled,\n", - ZR_DEVNAME(zr)); - dprintk(1, - KERN_ERR - "%s: v4l_fbuffer_alloc() - sorry, could not allocate %d V4L buffers of size %d KB.\n", - ZR_DEVNAME(zr), fh->v4l_buffers.num_buffers, - fh->v4l_buffers.buffer_size >> 10); - return -ENOBUFS; -#endif } } @@ -485,11 +427,6 @@ v4l_fbuffer_free (struct file *file) ClearPageReserved(MAP_NR(mem + off)); kfree((void *) fh->v4l_buffers.buffer[i].fbuffer); } -#if defined(CONFIG_BIGPHYS_AREA) - else - bigphysarea_free_pages((void *) fh->v4l_buffers. - buffer[i].fbuffer); -#endif fh->v4l_buffers.buffer[i].fbuffer = NULL; } -- 2.11.4.GIT
