Hello, I was trying kexec in sh3 (HP jornada 660lx: SH7709 - HD64461) using those kexec-tools. But it gets frozen when run "kexec -e". I would wish to know what might be the issue. Also, I used strace with "kexec -e" to see the last reboot system call: root@jornada6xx:~$ kexec -l /boot/zImage --append="root=/dev/sda1 mem=32M" root@jornada6xx:~$ root@jornada6xx:~$ kexec -f kexec 1.101 released 15 February 2005 ... ADDRESS of empty_zero can be set SHELL environment variable KEXEC_EMPTY_ZERO as default ... ADDRESS can be get in the following method in your system. .. 3) CONFIG_MEMORY_START + CONFIG_ZERO_PAGE_OFFSET in your kernel config file. root@jornada6xx:~$ Well, The kernel (2.6.23-rc5 from jlime) was built with CONFIG_MEMORY_START=0x0d000000 CONFIG_ZERO_PAGE_OFFSET=0x00001000 in the .config file. So i did: root@jornada6xx:~$ export KEXEC_EMPTY_ZERO=0x0d001000 root@jornada6xx:~$ strace kexec -e ... reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2, 0x45584543 /* LINUX_REBOOT_CMD_ ??? */Starting new kernel kexec information segment[0]: 0x0c001000 - 0x0c002000 (0x00001000) segment[1]: 0x0c210000 - 0x0c3b8000 (0x001a8000) start : 0x8c210000 nothing else happened.

sh: move sm501 serial port platform data into sm501.c
This patch moves the platform data for the 8250 block in the sm501 from the
board specific code to the sm501 specific mfd driver. This seems to work
well for now on r2d but in the future we should move the interrupt demux
code as well.

The port mapping should be fixed, so the pcmcia driver most likely suffers from some API change. Before we created a "junk" IRQ by setting irq_desc[].chip = &blabla_type, Im guessing the irq_desc now requires an actual interrupt action now. > > If this actually fixes PCMCIA for you today, then it bears a closer > looking at, but at a quick glance I don't see it having any impact these > days.

Greetings, Since I've been debugging the pcmcia driver, I thought of something andriy said 1-2 years ago when pcmcia was buggy. In order for 2.6.17 to have working pcmcia we needed to add this patch below. Andriy said he knew this wasn't the best way to solve it, but we should use it until he talked to you. Currently this isn't applied to neither jlime-current.git or any other git tree. Could you please give me some quick feedback on why this might be nessecary (or was). I always assumed It would be obselete ones MMIO transition was over. --- linux-2.6.17/include/asm-sh/io.h_orig 2006-09-17 22:52:10.000000000 +0000 +++ linux-2.6.17/include/asm-sh/io.h 2006-09-17 22:54:01.000000000 +0000 @@ -138,17 +138,17 @@ #define readl_relaxed(a) readl(a) /* Simple MMIO */ -#define ioread8(a) readb(a) -#define ioread16(a) readw(a) -#define ioread16be(a) be16_to_cpu(__raw_readw((a))) -#define ioread32(a) readl(a) -#define ioread32be(a) be32_to_cpu(__raw_readl((a))) - -#define iowrite8(v,a) writeb((v),(a)) -#define iowrite16(v,a) writew((v),(a)) -#define iowrite16be(v,a) __raw_writew(cpu_to_be16((v)),(a)) -#define iowrite32(v,a) writel((v),(a)) -#define iowrite32be(v,a) __raw_writel(cpu_to_be32((v)),(a)) +#define ioread8(a) inb(a) +#define ioread16(a) inw(a) +#define ioread16be(a) be16_to_cpu(inw((a))) +#define ioread32(a) inl(a) +#define ioread32be(a) be32_to_cpu(inl((a))) + +#define iowrite8(v,a) outb((v),(a)) +#define iowrite16(v,a) outw((v),(a)) +#define iowrite16be(v,a) outw(cpu_to_be16((v)),(a)) +#define iowrite32(v,a) outl((v),(a)) +#define iowrite32be(v,a) outl(cpu_to_be32((v)),(a)) #define ioread8_rep(a,d,c) insb((a),(d),(c)) #define ioread16_rep(a,d,c) insw((a),(d),(c)) |

The proper way to fix this is to get the port mapping right in the driver itself and just stick with regular MMIO accesses. There's no reason why this _requires_ non-MMIO, so it's purely a convenience thing. If this actually fixes PCMCIA for you today, then it bears a closer looking at, but at a quick glance I don't see it having any impact these days. |

I recommend you to use a more recent kernel to begin with. Many things have changed since 2.6.16. I suspect that older kernels didn't provide any masking and unmasking code for IRQ0. There is at least no such code in this old version: http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=blob;f=arch/sh/kernel/cpu/sh3/setup-sh7705.c;h=a55b8ce2c54c46e156319f674928e36f07bd7f15;hb=68abdbbb03476a60d932eeba0035dd5069afec38 There may be some board specific code that handles IRQ0 though, I'm not sure. But anyway, you need some code that masks and unmasks IRQ0 in IPRC. There is no IRQ0 interrupt in ipr_irq_table above so I suspect it is not supported in older kernels. The new intc tables should support that interrupt source out of the box though. Hope this helps! / magnus |

Write-through works fine on all of my 2-way and 4-way set associative dcaches, you're probably the only user of direct-mapped SH caches these days. I'll see if I can dig up a board with a direct-mapped cache or see if this is reproducable with EMODE disabled on 2-way. Does disabling the dcache work for you? |

I'm able to reproduce this, so I'll start doing some more debugging on it.. |

The problem is that the DMA doesn't work for the framebuffer as such but for the TA. Direct DMA is texture DMA and, afaics - I am still hacking at this when I get the time, which has been in short supply in the last few weeks - that is still about loading in a lot of TA parameters, just not asking the TA to process them. As you suggest, what I am looking at is replacing the generic PIO bitblit etc. Just not convinced it is possible with FP |

The basic framebuffer optimizations should extend to fast writes (via DMA and so) and not much else. There are fillrect/copyarea/imageblit primitives that you could presumably interface the TA for, but if you can't find a way to do it without FP, then you'll have to stick with the generic implementations. At this point you're stuck with doing all of your extensive optimizations in something like X or DirectFB. It's still worth doing deferred I/O for bulk page write-out via the DMAC for the framebuffer, which should at least give you some more bandwidth for things like X and mplayer which mmap() the device. |

Greetings, Since I've been debugging the pcmcia driver, I thought of something andriy said 1-2 years ago when pcmcia was buggy. In order for 2.6.17 to have working pcmcia we needed to add this patch below. Andriy said he knew this wasn't the best way to solve it, but we should use it until he talked to you. Currently this isn't applied to neither jlime-current.git or any other git tree. Could you please give me some quick feedback on why this might be nessecary (or was). I always assumed It would be obselete ones MMIO transition was over. --- linux-2.6.17/include/asm-sh/io.h_orig 2006-09-17 22:52:10.000000000 +0000 +++ linux-2.6.17/include/asm-sh/io.h 2006-09-17 22:54:01.000000000 +0000 @@ -138,17 +138,17 @@ #define readl_relaxed(a) readl(a) /* Simple MMIO */ -#define ioread8(a) readb(a) -#define ioread16(a) readw(a) -#define ioread16be(a) be16_to_cpu(__raw_readw((a))) -#define ioread32(a) readl(a) -#define ioread32be(a) be32_to_cpu(__raw_readl((a))) - -#define iowrite8(v,a) writeb((v),(a)) -#define iowrite16(v,a) writew((v),(a)) -#define iowrite16be(v,a) __raw_writew(cpu_to_be16((v)),(a)) -#define iowrite32(v,a) writel((v),(a)) -#define iowrite32be(v,a) __raw_writel(cpu_to_be32((v)),(a)) +#define ioread8(a) inb(a) +#define ioread16(a) inw(a) +#define ioread16be(a) be16_to_cpu(inw((a))) +#define ioread32(a) inl(a) +#define ioread32be(a) be32_to_cpu(inl((a))) + +#define iowrite8(v,a) outb((v),(a)) +#define iowrite16(v,a) outw((v),(a)) +#define iowrite16be(v,a) outw(cpu_to_be16((v)),(a)) +#define iowrite32(v,a) outl((v),(a)) +#define iowrite32be(v,a) outl(cpu_to_be32((v)),(a)) #define ioread8_rep(a,d,c) insb((a),(d),(c)) #define ioread16_rep(a,d,c) insw((a),(d),(c)) |

Greetings, Well, I've gotten a better graps of the problem. Here's how it should work : please note that Im not if demux runs before or after Int 78 (I presume before). Card inserted -> Int 36 (HD64461) -> demux -> Int 78 -> demux -> Int 79 -> Interrupt -> disable IRQ Int 78 is set using request_irq while Int 79 just sets irq_desc[79] = &hd64461_ss_type; to manage disable IRQ. Now, I cannot register 79 as a proper IRQ, since the dev_id would be the same(?).

Typed the wrong address first time... ---------- Forwarded message ---------- From: Adrian McMenamin <lkm...@gm...> Date: 6 Oct 2007 14:52 Subject: [PATCH] Fix SH4 DMAC API To: Paul Mundt <le...@li...> Cc: lin...@vg..., lin...@so... This patch fixes the DMA cascade by masking the correct bits. Tested and working with Dreamcast PVR2 DMA. With this patch applied the existing mainline code in arch/sh/drivers/dma/dma-sh.c works, whereas before I was patching that to get round this problem.

I am still toying with the idea of writing some accelerate 2D stuff for the Dreamcast PVR2 (essentially using the 3D capabilities to accelerate 2D). But the 3D hardware appears to natively rely on FP maths. Is there anyway round this? (As I have always understood SH4 kernel code does not use FP - though this won't touch the SH4 as such). Or is this a classic X11 v kernel issue? |
