SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

dm: x86: Set up interrupt routing from interrupt_init() At present interrupt routing is set up from arch_misc_init(). We can do it a little later instead, in interrupt_init(). This removes the manual pirq_init() call. Where the platform does not have an interrupt router defined in its device tree, no error is generated. Some platforms do not have this. Drop pirq_init() since it is no-longer used. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>

x86: Force 32-bit jumps in interrupt handlers Depending upon the compiler used, IRQ entries could vary in sizes. With GCC 5.x, the code generator will use short jumps for some IRQ entries but near jumps for others. For example, GCC 5.4.0 generates the following: $ objdump -d interrupt.o <snip> 00000207 <irq_18>: 207: 6a 12 push $0x12 209: eb 85 jmp 190 <irq_common_entry> 0000020b <irq_19>: 20b: 6a 13 push $0x13 20d: eb 81 jmp 190 <irq_common_entry> 0000020f <irq_20>: 20f: 6a 14 push $0x14 211: e9 7a ff ff ff jmp 190 <irq_common_entry> 00000216 <irq_21>: 216: 6a 15 push $0x15 218: e9 73 ff ff ff jmp 190 <irq_common_entry> This causes a problem in cpu_init_interrupts(), because the IDT setup assumed same sizes for all IRQ entries. GCC 4.x always generated 32-bit jumps, so this previously was not a problem. The fix is to force 32-bit near jumps for all entries within the inline assembly. This works for GCC 5.x, and 4.x was already using that form of jumping. Signed-off-by: Jason Tang <tang@jtang.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

Rewrite i386 interrupt handling Rewrite interrupt handling functionality for the i386 port. Separated functionality into separate CPU and Architecture components. It appears as if the i386 interrupt handler functionality was intended to allow multiple handlers to be installed for a given interrupt. Unfortunately, this functionality was not fully implemented and also had the problem that irq_free_handler() does not allow the passing of the handler function pointer and therefore could never be used to free specific handlers that had been installed for a given IRQ. There were also various issues with array bounds not being fully tested. I had two objectives in mind for the new implementation: 1) Keep the implementation as similar as possible to existing implementations. To that end, I have used the leon2/3 implementations as the reference 2) Seperate CPU and Architecture specific elements. All specific i386 interrupt functionality is now in cpu/i386/ with the high level API and architecture specific code in lib_i386. Functionality specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has been further split out into an individual file to allow for the implementation of the PIC architecture of the SC520 CPU (supports more IRQs) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>

2002-11-18 00:14:45 +00:00
Rewrite i386 interrupt handling Rewrite interrupt handling functionality for the i386 port. Separated functionality into separate CPU and Architecture components. It appears as if the i386 interrupt handler functionality was intended to allow multiple handlers to be installed for a given interrupt. Unfortunately, this functionality was not fully implemented and also had the problem that irq_free_handler() does not allow the passing of the handler function pointer and therefore could never be used to free specific handlers that had been installed for a given IRQ. There were also various issues with array bounds not being fully tested. I had two objectives in mind for the new implementation: 1) Keep the implementation as similar as possible to existing implementations. To that end, I have used the leon2/3 implementations as the reference 2) Seperate CPU and Architecture specific elements. All specific i386 interrupt functionality is now in cpu/i386/ with the high level API and architecture specific code in lib_i386. Functionality specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has been further split out into an individual file to allow for the implementation of the PIC architecture of the SC520 CPU (supports more IRQs) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>
