From a26968df0110bc2117e5572a07e285b183e68736 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Mon, 9 Jan 2006 20:53:08 -0800 Subject: [PATCH] [PATCH] fbdev: kyrofb: Driver cleanups - remove unneeded casts - use framebuffer_alloc/framebuffer_release to allocate/free memory - the pseudo_palette is always u32 regardless of bpp if using generic drawing functions Signed-off-by: Antonino Daplas Acked-by: Paul Mundt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/video/kyro/fbdev.c | 32 ++++++++++++++------------------ include/video/kyro.h | 1 + 2 files changed, 15 insertions(+), 18 deletions(-) diff --git a/drivers/video/kyro/fbdev.c b/drivers/video/kyro/fbdev.c index 5eb4d5c177..bcd359b6d4 100644 --- a/drivers/video/kyro/fbdev.c +++ b/drivers/video/kyro/fbdev.c @@ -73,8 +73,6 @@ static struct fb_var_screeninfo kyro_var __devinitdata = { .vmode = FB_VMODE_NONINTERLACED, }; -static struct kyrofb_info *currentpar; - typedef struct { STG4000REG __iomem *pSTGReg; /* Virtual address of PCI register region */ u32 ulNextFreeVidMem; /* Offset from start of vid mem to next free region */ @@ -309,7 +307,7 @@ enum { /* Accessors */ static int kyro_dev_video_mode_set(struct fb_info *info) { - struct kyrofb_info *par = (struct kyrofb_info *)info->par; + struct kyrofb_info *par = info->par; /* Turn off display */ StopVTG(deviceInfo.pSTGReg); @@ -402,7 +400,7 @@ static inline unsigned long get_line_length(int x, int bpp) static int kyrofb_check_var(struct fb_var_screeninfo *var, struct fb_info *info) { - struct kyrofb_info *par = (struct kyrofb_info *)info->par; + struct kyrofb_info *par = info->par; if (var->bits_per_pixel != 16 && var->bits_per_pixel != 32) { printk(KERN_WARNING "kyrofb: depth not supported: %u\n", var->bits_per_pixel); @@ -478,7 +476,7 @@ static int kyrofb_check_var(struct fb_var_screeninfo *var, struct fb_info *info) static int kyrofb_set_par(struct fb_info *info) { - struct kyrofb_info *par = (struct kyrofb_info *)info->par; + struct kyrofb_info *par = info->par; unsigned long lineclock; unsigned long frameclock; @@ -536,20 +534,22 @@ static int kyrofb_set_par(struct fb_info *info) static int kyrofb_setcolreg(u_int regno, u_int red, u_int green, u_int blue, u_int transp, struct fb_info *info) { + struct kyrofb_info *par = info->par; + if (regno > 255) return 1; /* Invalid register */ if (regno < 16) { switch (info->var.bits_per_pixel) { case 16: - ((u16*)(info->pseudo_palette))[regno] = + par->palette[regno] = (red & 0xf800) | ((green & 0xfc00) >> 5) | ((blue & 0xf800) >> 11); break; case 32: red >>= 8; green >>= 8; blue >>= 8; transp >>= 8; - ((u32*)(info->pseudo_palette))[regno] = + par->palette[regno] = (transp << 24) | (red << 16) | (green << 8) | blue; break; } @@ -675,6 +675,7 @@ static int __devinit kyrofb_probe(struct pci_dev *pdev, const struct pci_device_id *ent) { struct fb_info *info; + struct kyrofb_info *currentpar; unsigned long size; int err; @@ -683,14 +684,11 @@ static int __devinit kyrofb_probe(struct pci_dev *pdev, return err; } - size = sizeof(struct fb_info) + sizeof(struct kyrofb_info) + 16 * sizeof(u32); - info = kmalloc(size, GFP_KERNEL); + info = framebuffer_alloc(sizeof(struct kyrofb_info), &pdev->dev); if (!info) return -ENOMEM; - memset(info, 0, size); - - currentpar = (struct kyrofb_info *)(info + 1); + currentpar = info->par; kyro_fix.smem_start = pci_resource_start(pdev, 0); kyro_fix.smem_len = pci_resource_len(pdev, 0); @@ -716,8 +714,7 @@ static int __devinit kyrofb_probe(struct pci_dev *pdev, info->fbops = &kyrofb_ops; info->fix = kyro_fix; - info->par = currentpar; - info->pseudo_palette = (void *)(currentpar + 1); + info->pseudo_palette = currentpar->palette; info->flags = FBINFO_DEFAULT; SetCoreClockPLL(deviceInfo.pSTGReg, pdev); @@ -741,7 +738,6 @@ static int __devinit kyrofb_probe(struct pci_dev *pdev, fb_memset(info->screen_base, 0, size); - info->device = &pdev->dev; if (register_framebuffer(info) < 0) goto out_unmap; @@ -757,7 +753,7 @@ static int __devinit kyrofb_probe(struct pci_dev *pdev, out_unmap: iounmap(currentpar->regbase); iounmap(info->screen_base); - kfree(info); + framebuffer_release(info); return -EINVAL; } @@ -765,7 +761,7 @@ out_unmap: static void __devexit kyrofb_remove(struct pci_dev *pdev) { struct fb_info *info = pci_get_drvdata(pdev); - struct kyrofb_info *par = (struct kyrofb_info *)info->par; + struct kyrofb_info *par = info->par; /* Reset the board */ StopVTG(deviceInfo.pSTGReg); @@ -789,7 +785,7 @@ static void __devexit kyrofb_remove(struct pci_dev *pdev) unregister_framebuffer(info); pci_set_drvdata(pdev, NULL); - kfree(info); + framebuffer_release(info); } static int __init kyrofb_init(void) diff --git a/include/video/kyro.h b/include/video/kyro.h index 1bed37cfa6..dba7de2ee4 100644 --- a/include/video/kyro.h +++ b/include/video/kyro.h @@ -15,6 +15,7 @@ struct kyrofb_info { void __iomem *regbase; + u32 palette[16]; u32 HTot; /* Hor Total Time */ u32 HFP; /* Hor Front Porch */ u32 HST; /* Hor Sync Time */ -- 2.39.5
